Is it possible using php's XMLWriter to insert a new node to an existing xml file, and then save the file. This would be much more benficial to me that actually creating a enw file every time i want to update an xml file.
Hi there,
is there a way to rebuild Mac OSX Snow Leopard's Dashboard Widget 'Web Clip' on a PHP website?
Something like a crawler or scraper.
I thought about using file_get_contents to getting the page content into the page, but how do I select a section on the external page? And does this work with session/login content as well?
I'm happy for any kind of suggestions!
Cheers
Using PHP: How can I create an image to display an email address (to help reduce spam)?
Meaning, if I want to display "[email protected]" on my web page, since crawlers can easily find that text - I want to display the email address as an image that says "[email protected]".
How do I do that? I want the font to be:
color: #20c
font: 11px normal tahoma
Hi have some forms that I want to use some basic php validation (regular expressions) on, how do you go about doing it? I have just general text input, usernames, passwords and date to validate. I would also like to know how to check for empty input boxes. I have looked on the interenet for this stuff but I haven't found any good tutorials.
Thanks
Hi,
I have a php script for image upload as below
<?php
$LibID = $_POST[name];
define ("MAX_SIZE","10000");
function getExtension($str) {
$i = strrpos($str,".");
if (!$i) { return ""; }
$l = strlen($str) - $i;
$ext = substr($str,$i+1,$l);
return $ext;
}
$errors=0;
$image=$_FILES['image']['name'];
if ($image)
{
$filename = stripslashes($_FILES['image']['name']);
$extension = getExtension($filename);
$extension = strtolower($extension);
if (($extension != "jpg") && ($extension != "jpeg"))
{
echo '<h1>Unknown extension!</h1>';
$errors=1;
exit();
}
else
{
$size=filesize($_FILES['image']['tmp_name']);
if ($size > MAX_SIZE*1024)
{
echo '<h1>You have exceeded the size limit!</h1>';
$errors=1;
exit();
}
$image_name=$LibID.'.'.$extension;
$newname="uimages/".$image_name;
$copied = copy($_FILES['image']['tmp_name'], $newname);
if (!$copied)
{
echo '<h1>image upload unsuccessfull!</h1>';
$errors=1;
exit();
}}}
?>
which uploads the image file to a folder "uimages" in the root. I have made changes in the html file for the compact display of the image by defining "max-height" and "max-width". But i want to resize the image file on upload. The image file may have a maximum width of 100px and maximum height of 150px. The image proportions must be constrained. That is, the image may be smaller than the above dimensions, but, it should not exceed the limit. How can I make this possible??
Thanks in advance :)

I'm using PHP to upload an image from a form to the server and want to rename the image lastname_firstname.[original extension]. I currently have:
move_uploaded_file($_FILES["picture"]["tmp_name"], "peopleimages/" . "$_POST[lastname]" . '_' . "$_POST[firstname]")
which, of course, renames the file lastname_firstname without an extension. How do I rename the file but keep the extension?
Thanks!
I dont know much about classes, but have a reasonable knowledge of PHP/MySQL.
But why should I learn classes? I know they are important but what benefits can I see using them that I cant with?
This is kind of an academic question, so feel free to exit now. I've had a dig through Stack for threads pertaining to URL/Controller mapping in MVC frameworks - in particular this one:
http://stackoverflow.com/questions/125677/php-application-url-routing
So far, I can ascertain two practices:
1: dynamic mapping through parsing the URL string (exploded on '/')
2: pattern matching matching url to config file containing available routes
I wanted to get some feedback (or links to some other threads/articles) from folks regarding their views on how best to approach this task.
In my application am submiting my form by using post for a php page.

Hi,
I have a array inside my PHP app that looks like this:
Array
(
[0] => Array
(
[name] => Name1
[language] => 1
)
[1] => Array
(
[name] => Name2
[language] => 1
)
)
How can I check that "language" with value 1 doesnt appear twice, as effectively as possible?
I need a regular in expression in PHP that I can plug into preg_match_all and find if an @ sign and any character number or letter follows right after that. So if I put "@patrick hello there" it will come up true, if I put in "I saw her @ the mall" it will be false.
Thank you :)
There has always been a confusion with preg_match in php.
I have a string like this:
apsd_01_03s_somedescription
apsd_02_04_somedescription
Can I use preg_match to strip off anything from 3rd underscore including the 3rd underscore.
thanks.
Hi experts,

Any help will be appreciated.

Ok I wrote my own version of SALT I call it salty lol don't make fun of me.. Anyway the registration part of my script as follows is working 100% correctly.
//generate SALTY my own version of SALT and I likes me salt.. lol
function rand_string( $length ) {
$chars = "ABCDEFGHIJKLMNOPQRSTUWXYZabcdefghijklmnopqrstuwxyz1234567890";
$size = strlen( $chars );
for( $i = 0; $i < $length; $i++ ) {
$str .= $chars[ rand( 0, $size - 1 ) ];
}
return $str;
}
$salty = rand_string( 256 );
//generate my extra salty pw
$password = crypt('password');
$hash = $password . $salty;
$newpass = $hash;
//insert the data in the database
include ('../../scripts/dbconnect.php');
//Update db record with my salty pw ;)
// TESTED WITH AND WITHOUT SALTY
//HENCE $password and $newpass
mysql_query("UPDATE `Register` SET `Password` = '$password' WHERE `emailinput` = '$email'");
mysql_close($connect);
However my LOGIN script is failing. I have it setup to TEST and echo if its login or not. It always returns FAILED. I entered the DB and changed the crypted salty pw to "TEST" and I got a SUCCESS. So my problem is somewhere in this LOGIN script I assume. Now I am not sure how to implement my $Salty in this. But also be advised that even without SALTY (just using crypt to store my pass) - I was still unable to perform a login successfully. And if you're gonna suggest i use blowfish - note that my webhost doesn't have it supported and i don't know how to install it.
here's my login script:
if (isset($_POST['formsubmitted']))
{
include ('../../scripts/dbconnect.php');
$username = mysql_real_escape_string($_POST['username']);
$password = crypt(mysql_real_escape_string($_POST['password']));
$qry = "SELECT ID FROM Register WHERE emailinput='$username' AND Password='$password'";
$result = mysql_query($qry);
if(mysql_num_rows($result) > 0)
{
echo 'SUCCESS';
//START SESSION
}
else
{
echo 'FAILED';
//YOU ARE NOT LOGGED IN
}
}
So what's wrong with this login? Why isn't it working just using the crypt/storing only crypt?
How can i make it work storing both the crypt and randomly generated SALTY :) ?
Ty advance
You all know about restrictions that exist in shared environment, so with that in mind, please suggest me a php function or something with the help of which I could stream my videos and other files. I have a lot of videos on the server, unlimited bandwidth and disk space, but I am limited in ram and cpu.
There is a way to check with a "IF" if a function fails in php?
Ex.
If (getimagesize($image) returns and error) {
echo 'Error: function dont work';
}
else
{
// do something
}
Thanks!

Looking for some [freeware/opensource] tool in order to make it easy to profile a big php project on win32 platform. Need to find out which part of code is most time consuming.
It's hard to manually put timing function for each function, loop...
