  • How can I multiply each item in an array easily with PHP?

    - by Henry
    I have an array called $times. It is a list of small numbers (15,14,11,9,3,2). These will be user submitted and are supposed to be minutes. As PHP time works on seconds, I would like to multiply each element of my array by 60. I've been playing around with array_walk and array_map but I can't get those working :S Thanks.

  • Delphi 6: How to search a dynamic array for sub-string quickly?

    - by Robert Oschler
    How can I search a dynamic array of char in Delphi 6 for a sub-string and get back an index to a match, not a pointer? I've seen functions in Delphi 6 that do this for strings but not for dynamic char arrays. There is a function called SearchBuf but that function returns a PChar pointer to the match location when what I need is the array index of the match. Thanks.

    Hi all, Basic array question: $string = "The quick brown cat"; $check1 = "apple"; $check2 = "ball"; $check3 = "cat"; if ( (stripos($string, $check1) === false) || (stripos($string, $check2) === false) || (stripos($string, $check3) === false) ) { echo "Fail"; } How do I condense the above using an array ($check[])? Thanks!

  • Is it okay to use array[key] in PHP?

    - by terrani
    Hi, I have a simple question. Is it okay to use array without single or double quotion like $array[key]? I thought it is bad because PHP look for constant first if I don't use single or doulbe quotion. One of my colleagues told me that it does not matter. WHat do you guys think?

  • Unable to access intel fake RAID 1 array in Fedora 14 after reboot

    - by Sim
    Hello everyone, 1st I am relatively new to linux (but not to *nix). I have 4 disks assembled in the following intel ahci bios fake raid arrays: 2x320GB RAID1 - used for operating systems md126 2x1TB RAID1 - used for data md125 I have used the raid of size 320GB to install my operating system and the second raid I didn't even select during the installation of Fedora 14. After successful partitioning and installation of Fedora, I tried to make the second array available, it was possible to make it visible in linux with mdadm --assembe --scan , after that I created one maximum size partition and 1 maximum size ext4 filesystem in it. Mounted, and used it. After restart - a few I/O errors during boot regarding md125 + inability to mount the filesystem on it and dropped into repair shell. I commented the filesystem in fstab and it booted. To my surprise, the array was marked as "auto read only": [root@localhost ~]# cat /proc/mdstat Personalities : [raid1] md125 : active (auto-read-only) raid1 sdc[1] sdd[0] 976759808 blocks super external:/md127/0 [2/2] [UU] md127 : inactive sdc[1](S) sdd[0](S) 4514 blocks super external:imsm md126 : active raid1 sda[1] sdb[0] 312566784 blocks super external:/md1/0 [2/2] [UU] md1 : inactive sdb[1](S) sda[0](S) 4514 blocks super external:imsm unused devices: <none> [root@localhost ~]# and the partition in it was not available as device special file in /dev: [root@localhost ~]# ls -l /dev/md125* brw-rw---- 1 root disk 9, 125 Jan 6 15:50 /dev/md125 [root@localhost ~]# But the partition is there according to fdisk: [root@localhost ~]# fdisk -l /dev/md125 Disk /dev/md125: 1000.2 GB, 1000202043392 bytes 19 heads, 10 sectors/track, 10281682 cylinders, total 1953519616 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x1b238ea9 Device Boot Start End Blocks Id System /dev/md125p1 2048 1953519615 976758784 83 Linux [root@localhost ~]# I tried to "activate" the array in different ways (I'm not experienced with mdadm and the man page is gigantic so I was only browsing it looking for my answer) but it was impossible - the array would still stay in "auto read only" and the device special file for the partition it will not be in /dev. It was only after I recreated the partition via fdisk that it reappeared in /dev... until next reboot. So, my question is - How do I make the array automatically available after reboot? Here is some additional information: 1st I am able to see the UUID of the array in blkid: [root@localhost ~]# blkid /dev/sdc: UUID="b9a1149f-ae11-4fc8-a600-0d77354dc42a" SEC_TYPE="ext2" TYPE="ext3" /dev/sdd: UUID="b9a1149f-ae11-4fc8-a600-0d77354dc42a" SEC_TYPE="ext2" TYPE="ext3" /dev/md126p1: UUID="60C8D9A7C8D97C2A" TYPE="ntfs" /dev/md126p2: UUID="3d1b38a3-b469-4b7c-b016-8abfb26a5d7d" TYPE="ext4" /dev/md126p3: UUID="1Msqqr-AAF8-k0wi-VYnq-uWJU-y0OD-uIFBHL" TYPE="LVM2_member" /dev/mapper/vg00-rootlv: LABEL="_Fedora-14-x86_6" UUID="34cc1cf5-6845-4489-8303-7a90c7663f0a" TYPE="ext4" /dev/mapper/vg00-swaplv: UUID="4644d857-e13b-456c-ac03-6f26299c1046" TYPE="swap" /dev/mapper/vg00-homelv: UUID="82bd58b2-edab-4b4b-aec4-b79595ecd0e3" TYPE="ext4" /dev/mapper/vg00-varlv: UUID="1b001444-5fdd-41b6-a59a-9712ec6def33" TYPE="ext4" /dev/mapper/vg00-tmplv: UUID="bf7d2459-2b35-4a1c-9b81-d4c4f24a9842" TYPE="ext4" /dev/md125: UUID="b9a1149f-ae11-4fc8-a600-0d77354dc42a" SEC_TYPE="ext2" TYPE="ext3" /dev/sda: TYPE="isw_raid_member" /dev/md125p1: UUID="420adfdd-6c4e-4552-93f0-2608938a4059" TYPE="ext4" [root@localhost ~]# Here is how /etc/mdadm.conf looks like: [root@localhost ~]# cat /etc/mdadm.conf # mdadm.conf written out by anaconda MAILADDR root AUTO +imsm +1.x -all ARRAY /dev/md1 UUID=89f60dee:e46a251f:7475814b:d4cc19a9 ARRAY /dev/md126 UUID=a8775c90:cee66376:5310fc13:63bcba5b ARRAY /dev/md125 UUID=b9a1149f:ae114fc8:a6000d77:354dc42a [root@localhost ~]# here is how /proc/mdstat looks like after I recreate the partition in the array so that it becomes available: [root@localhost ~]# cat /proc/mdstat Personalities : [raid1] md125 : active raid1 sdc[1] sdd[0] 976759808 blocks super external:/md127/0 [2/2] [UU] md127 : inactive sdc[1](S) sdd[0](S) 4514 blocks super external:imsm md126 : active raid1 sda[1] sdb[0] 312566784 blocks super external:/md1/0 [2/2] [UU] md1 : inactive sdb[1](S) sda[0](S) 4514 blocks super external:imsm unused devices: <none> [root@localhost ~]# Detailed output regarding the array in subject: [root@localhost ~]# mdadm --detail /dev/md125 /dev/md125: Container : /dev/md127, member 0 Raid Level : raid1 Array Size : 976759808 (931.51 GiB 1000.20 GB) Used Dev Size : 976759940 (931.51 GiB 1000.20 GB) Raid Devices : 2 Total Devices : 2 Update Time : Fri Jan 7 00:38:00 2011 State : clean Active Devices : 2 Working Devices : 2 Failed Devices : 0 Spare Devices : 0 UUID : 30ebc3c2:b6a64751:4758d05c:fa8ff782 Number Major Minor RaidDevice State 1 8 32 0 active sync /dev/sdc 0 8 48 1 active sync /dev/sdd [root@localhost ~]# and /etc/fstab, with /data commented (the filesystem that is on this array): # # /etc/fstab # Created by anaconda on Thu Jan 6 03:32:40 2011 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info # /dev/mapper/vg00-rootlv / ext4 defaults 1 1 UUID=3d1b38a3-b469-4b7c-b016-8abfb26a5d7d /boot ext4 defaults 1 2 #UUID=420adfdd-6c4e-4552-93f0-2608938a4059 /data ext4 defaults 0 1 /dev/mapper/vg00-homelv /home ext4 defaults 1 2 /dev/mapper/vg00-tmplv /tmp ext4 defaults 1 2 /dev/mapper/vg00-varlv /var ext4 defaults 1 2 /dev/mapper/vg00-swaplv swap swap defaults 0 0 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 [root@localhost ~]# Thanks in advance to everyone that even read this whole issue :-)

  • Database Design for a double entry accounting system

    - by Khou
    Should journal entries be recorded in a database design? In the real world it makes sense to keep a daily entry book, then later transfer the daily entry book into double entry accounts. but in the computerized version, doing this produces duplicate records and that doesn't quite make sense? ???? What i mean is 1) user enter details , it gets recorded (this would be called the journalbook in real life) 2) the software does all the double entry accounting then references the journalbook and splits up the transaction into the double entry accounting system.

  • double.NaN Equality in MS Test

    - by RichK
    Why am I getting this result? [TestMethod] public void nan_test() { Assert.AreEqual(1, double.NaN, 1E-1); <-- Passes Assert.AreEqual(1, double.NaN); <-- Fails } What difference does the delta have in asserting NaN equals a number? Surely it should always return false. I am aware of IsNaN, but that's not useful here (see below). Background: I have a function returning NaN (erroneously) , it was meant to be a real number but the test still passed. I'm using the delta because it's double precision equality, the original test used 1E-9.

  • Is Updating double operation atomic

    - by Yan Cheng CHEOK
    In Java, updating double and long variable may not be atomic, as double/long are being treated as two separate 32 bits variables. http://java.sun.com/docs/books/jls/second_edition/html/memory.doc.html#28733 In C++, if I am using 32 bit Intel Processor + Microsoft Visual C++ compiler, is updating double (8 byte) operation atomic? I cannot find much specification mention on this behavior. When I say "atomic variable", here is what I mean : Thread A trying to write 1 to variable x. Thread B trying to write 2 to variable x. We shall get value 1 or 2 out from variable x, but not an undefined value.

  • PHP mssql_query double quotes cannot be used

    - by Nilesh
    Hi all, In java-jdbc, I can easily run the following SQL (NOTE the double quotes around columns and table names) Select cus."customer_id" , cus."organisation_or_person" , cus."organisation_name" , cus."first_name" , cus."last_name" , cus."date_became_customer" , cus."other_customer_details" From "Contact_Management"."dbo"."Customers" cus But the same query in PHP errors out saying invalid syntax "Warning: mssql_query() [function.mssql-query]: message: Incorrect syntax near 'customer_id'. (severity 15) " But If remove all the double quotes, the query works fine and no errors. The query is ported from a java application so I would like to keep the double quotes and the SQL as it is. Any alternative solutions? Thank you Nilesh

  • How to convert culture specific double using TypeConverter?

    - by Christian
    Hi I have a problem with the TypeConverter class. It works fine with CultureInvariant values but cannot convert specific cultures like english 1000 seperators. Below is a small test program that I cannot get to work. using System; using System.Globalization; using System.ComponentModel; namespace TestConvertCulture { class Program { static void Main() { try { var culture = new CultureInfo( "en" ); TypeConverter typeConverter = TypeDescriptor.GetConverter( typeof ( double ) ); double value = (double)typeConverter.ConvertFromString( null, culture, "2,999.95" ); Console.WriteLine( "Value: " + value ); } catch( Exception e ) { Console.WriteLine( "Error: " + e.Message ); } } } }

  • Double encoded url being fully decoded in ASP.NET

    - by Brad R
    I have just come across something that is quite strange and yet I haven't found any mention on the interwebs of others having the same problem. If I hit my ASP.NET application with a double encoded url then the Request["myQueryParam"] will do a double decode of the query for me. This is not desirable as I have double encoded my query string for a good reason. Can others confirm I'm not doing something obviously wrong, and why this would happen. A solution to prevent it, without doing some nasty query string parsing, would be great too! As an example if you hit the url: http://localhost/MyApp?originalUrl=http%3a%2f%2flocalhost%2fAction%2fRedirect%3fUrl%3d%252fsomeUrl%253futm_medium%253dabc%2526utm_source%253dabc%2526utm_campaign%253dabc (For reference %25 is the % symbol) Then look at the Request["originalUrl"] (page or controller) the string returned is: http://localhost/Action/Redirect?Url=/someUrl?utm_medium=abc&utm_source=abc&utm_campaign=abc I would expect: http://localhost/Action/Redirect?Url=%2fsomeUrl%3futm_medium%3dabc%26utm_source%3dabc%26utm_campaign%3dabc I have also checked in Fiddler and the URL is being passed to the server correctly (one possible culprit could have been the browser decoding the URL before sending).

  • How to represent double values as circles in a 2d matrix in java

    - by marco
    Hello, so I want to write a matrix explorer which enables me to reorder rows and columns of a matrix. For this porpouse I used the Jtable class. Now the problem that I have is that it is very difficult to reorder a matrix by looking at double values, so I would like to print the matrix not with the double values but with circles in which the radius of the circle represents the value. So that I can tell the difference between big values and small values quicker. Anybody has any idea how I can turn this double values into filled circles with JTable or any table class for that matter?

  • Why does PHP overwrite values when I iterate through this array twice (by reference, by value)

    - by jeremy
    If I iterate through an array twice, once by reference and then by value, PHP will overwrite the last value in the array if I use the same variable name for each loop. This is best illustrated through an example: $array = range(1,5); foreach($array as &$element) { $element *= 2; } print_r($array); foreach($array as $element) { } print_r($array); Output: Array ( [0] = 2 [1] = 4 [2] = 6 [3] = 8 [4] = 10 ) Array ( [0] = 2 [1] = 4 [2] = 6 [3] = 8 [4] = 8 ) Note that I am not looking for a fix, I am looking to understand why this is happening. Also note that it does not happen if the variable names in each loop are not each called $element, so I'm guessing it has to do with $element still being in scope and a reference after the end of the first loop.

  • Double Buffering with awt

    - by DDP
    Is double buffering (in java) possible with awt? Currently, I'm aware that swing should not be used with awt, so I can't use BufferStrategy and whatnot. If double buffering is possible with awt, do I have to write the buffer by hand? Unlike swing, awt doesn't seem to have the same built-in double buffering capability. If I do have to write the code by hand, is there a good tutorial to look at? Or is it just easier/advisable for a novice programmer to use swing instead? Sorry about the multi-step question. Thanks for your time :)

  • How to search array for duplicates using a single array?

    - by patrick
    I am checking a list of 10 spots, each spot w/ 3 top users to see if a user is in an array before echoing and storing. foreach($top_10['top_10'] as $top10) //loop each spot { $getuser = ltrim($top10['url'], " users/" ); //strip url if ($usercount < 3) { if ((array_search($getuser, $array) !== true)) { echo $getuser; $array[$c++] = $getuser; } else { echo "duplicate <br /><br />"; } } } The problem I am having is that for every loop, it creates a multi-dimensional array for some reason which only allows array_search to search the current array and not all combined. I am wanting to store everything in the same $array. This is what I see after a print_r($array) Array ( [0] => 120728 [1] => 205247 ) Array ( [0] => 232123 [1] => 091928 )

  • Create new Array of parameter type

    - by pimvdb
    I'm trying to create a function to parse out all values in a multidimensional Array with all but one dimension given. The details are not relevant, but for this function I need to return an one-dimensional Array containing values of the same type the original multidimensional Array has. To pass any Array with any dimension to my function, I declared the type of this parameter as Array. However, how would I create a new Array of that specific type (e.g. Integer)? Currently I have the following code: Function GetRow(ByVal arr As Array) As Array Dim result As (...) 'This should be Integer() if arr contains Integers, etc. Return result End Function How do I declare the type of result to make it having the same type of values as arr? New Array is not possible as it is declared MustInherit. Thanks a lot.
