  • String useless character strip - PHP

    - by Zoltan Repas
    Hi! I've got a huge problem. I made a special ID for the things in our webpage. Let's see an example: H0059 - this is the special ID called registration number. The last two chars are the things' id. I'd like to cut off the useless characters, to get the real ID, what means strip the first char, and all the 0s before any other numbers. (Example: L0745 = 745, V1754 = 1754, L0003 = 3, B0141 = 141, P0040 = 40, V8000 = 8000) Please help me in this. I've tried with strreplace and explode but failed :( Thanks for the help.

  • PHP validating integers

    - by Mikk
    Hi, I was wondering, what would be the best way to validate an integer. I'd like this to work with strings as well, so I could to something like (string)+00003 - (int)3 (valid) (string)-027 - (int)-27 (valid) (int)33 - (int)33 (valid) (string)'33a' - (FALSE) (invalid) That is what i've go so far: function parseInt($int){ //If $int already is integer, return it if(is_int($int)){return $int;} //If not, convert it to string $int=(string)$int; //If we have '+' or '-' at the beginning of the string, remove them $validate = ($int[0] === '-' || $int[0] === '+')?substr($int, 1):$int; //If $validate matches pattern 0-9 convert $int to integer and return it //otherwise return false return preg_match('/^[0-9]+$/', $validate)?(int)$int:FALSE; } As far as I tested, this function works, but it looks like a clumsy workaround. Is there any better way to write this kind of function. I've also tried filter_var($foo, FILTER_VALIDATE_INT); but it won't accept values like '0003', '-0' etc.

  • PHP preg_replace - Very quick question

    - by RC
    Masters of regular expressions, please help! See this string: $string = "http://www.url.com/?fieldA=123&fieldB=456&fieldC=789"; Assuming "fieldB" always has a positive non-decimal numerical value (but not necessarily three digits long), what preg_replace command do I need to remove it completely, such that the string will then read: $string = "http://www.url.com/?fieldA=123&fieldC=789"; Thanks!

  • PHP readdir() not returning files in alphabetical order

    - by Buggabill
    I am reading through a directory with some pictures and such using a pretty simple implementation of readdir() like the following: if ($handle = opendir($path)) { while (false !== ($szFilename = readdir($handle))) { if ($szFilename[0] !== '.') { if (is_file($path.$szFilename)) { // do stuff } } } } The problem that I am having is that the files are not being read in alphabetical order as the docs for readdir() state: Returns the filename of the next file from the directory. The filenames are returned in the order in which they are stored by the filesystem. Another weird thing is that, on the local testing server, the same code works great. This is running on a server using the LAMP stack in both cases. I know that I can build an array and just sort it, but I was wondering if I was missing something in what I was doing. Thanks for any insight!

  • S3 file Uploading from Mac app though PHP?

    - by Ilija Tovilo
    I have asked this question before, but it was deleted due too little information. I'll try to be more concrete this time. I have an Objective-C mac application, which should allow users to upload files to S3-storage. The s3 storage is mine, the users don't have an Amazon account. Until now, the files were uploaded directly to the amazon servers. After thinking some more about it, it wasn't really a great concept, regarding security and flexibility. I want to add a server in between. The user should authenticate with my server, the server would open a session if the authentication was successful, and the file-sharing could begin. Now my question. I want to upload the files to S3. One option would be to make a POST-request and wait until the server would receive the file. Problems here are, that there would be a delay, when the file is being uploaded from my server to the S3 servers, and it would double the uploading time. Best would be, if I could validate the request, and then redirecting it, so the client uploads it directly to the s3-storage. Not sure if this is possible somehow. Uploading directly to S3 doesn't seem to be very smart. After looking into other apps like Droplr and Dropmark, it looks like they don't do this. Btw. I did this using Little Snitch. They have their api on their own web-server, and that's it. Could someone clear things up for me? EDIT How should I transmit my files to S3? Is there a way to "forward" it, or do I have to upload it to my server and then upload it from there to S3? Like I said, other apps can do this efficiently and without the need of communicating with S3 directly.

  • How to check with PHP does a SQL database already have

    - by Dan Horvat
    I've tried to find the answer to this question but none of the answers fit. I have two databases, one has 15.000.000 entries and I want to extract the necessary data and store it in a much smaller database with around 33.000 entries. Both databases are open at the same time. Or at least they should be. While having the big database open and extracting the entries from it, is it possible to check whether the value already exists in the smaller database? I just need some generic way which checks that.

  • How to add a suffix at the end of a string in PHP

    - by Golem
    I am trying to add a .html suffix at the end of all strings supplied by the user before it is entered into the database. Here's my code so far: strtolower(str_replace(" ", "_", $postTitle)); The above takes the title of the post the user it trying to make, turns it to lower case, replaces all white spaces with underscores and makes it ready to be entered into a database column called post_url. I just need it to do one more thing and that's to add a .html at the end of each post url. What is the function to do this?
