PHP - Preg_match Problem

Hi,

I have the following code:


Code: [Select]

<?
Header("content-type: application/x-javascript");
function returnimages($dirname="./windows/prezentare_jpg/") {
$files = array();
$curimage=0;
if($handle = opendir($dirname)) {
while(false !== ($file = readdir($handle))){
if(preg_match('/.jpg$/i', $file)){
echo 'galleryarray['.$curimage.']="'.$file .'";';
$curimage++;
}
}
closedir($handle);
}
return($files);
}
echo 'var galleryarray=new Array();';
returnimages();
?>


Ran on windows (xampp 1.7.7, PHP 5.3.8, Apache 2.2.21) it returns the correct alfabetical/numerical order:

Code: [Select]
var galleryarray=new Array();galleryarray[0]="01.jpg";galleryarray[1]="02.jpg";galleryarray[2]="03.jpg";galleryarray[3]="04.jpg";galleryarray[4]="05.jpg";galleryarray[5]="06.jpg";galleryarray[6]="07.jpg";galleryarray[7]="08.jpg";galleryarray[8]="09.jpg";galleryarray[9]="10.jpg";galleryarray[10]="11.jpg";galleryarray[11]="12.jpg";


Ran on linux (PHP 5.3.8, Apache 2.2.21) it returns an incorrect order:

Code: [Select]

var galleryarray=new Array();galleryarray[0]="06.jpg";galleryarray[1]="01.jpg";galleryarray[2]="08.jpg";galleryarray[3]="10.jpg";galleryarray[4]="04.jpg";galleryarray[5]="11.jpg";galleryarray[6]="05.jpg";galleryarray[7]="03.jpg";galleryarray[8]="07.jpg";galleryarray[9]="09.jpg";galleryarray[10]="02.jpg";galleryarray[11]="12.jpg";


I need the script to run correctly on the linux server.
What could be the problem? What can i try?

Hi im trying to do a registration form and i am new to using preg_match. I keep getting the error

"( ! ) Warning: preg_match() [function.preg-match]: No ending delimiter '^' found in C:\wamp\www\registration1.php on line 67"

and for every other line I use preg_match. this is an example of how i have used it

Code: [Select]
if (  preg_match('^[[:alnum:]\.\'\-]{4,50}$', stripslashes(trim($_POST['UserName']))) )
{
$UserName = mysql_real_escape_string($_POST['UserName']);
        $query = "SELECT UserName FROM Users WHERE UserName = '$UserName'";
        $result = @mysql_query($query);
        $num = @mysql_num_rows($result);
 im such a noob at this can someone please help me

I would also like to add that I have read the http://www.php.net/manual/en/function.preg-match.php page but i dont really understand it.

I need to select an array item based on my preg result. for example:

Code: [Select]
$content = 'test-1';

$match = preg_replace('|test-([0-9])|', $array['\\1'], $content);
is this possible?

Hey guys,

In my contact form i have the action: preg_match but i've come accross a problem.

Problem: Warning: preg_match() [function.preg-match]: No ending delimiter '^' found in C:\Program Files (x86)\wamp\www\ts\contact.php on line 34

Code:$error_message = "";
$email_exp = "^[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$";
  if(!preg_match($email_exp,$email_from)) {
   $error_message .= 'The Email Address you entered does not appear to be valid.<br />';


Thanks in advance

Hi, I have the following code which FTPs to a site, gets the source code for a HTML file and then puts the data inbetween <TITLE> and </TITLE> into an array and this works fine:
<?php
$file = file_get_contents("ftp://user:pass@domain/public_html/index.html", "r");

if (!$file) {
    echo "<p>Unable to open remote file.\n";
    exit;
}
preg_match_all ('/<TITLE>(.*)<\/TITLE>/msU', $file, $matches, PREG_SET_ORDER);

print_r ($matches);

?>

Rather than finding a match for data between <TITLE> and </TITLE> however I would like it to pull back what is inbetween the following:

<!--START--> and <!--END-->

I have tried the following but it doesn't put anything into the array:

preg_match_all ('/<!--START-->(.*)<\/!--END-->/msU', $file, $matches, PREG_SET_ORDER);

This is the content of the html file if this helps:

Code: [Select]
<TITLE>The Title</TITLE>
<!--START--><p><strong>Some Text</strong></p>
<p><strong><img src="images/IMAG0152_2.jpg" alt="" width="200" height="100" /></strong></p>
<!--END-->

i can get a match on stuff between TITLEs but not START and END.. I'm not sure how to change preg_match_all to work!! i've tried loads of combinations but can't get any to work, but i'm not really sure on modifiers and patterns or escaping etc,  if anyone could help that would be great.

Thanks in advance

Hi,   I don't know much about php. Recently my host updated php version to 5.4 and i function eregi() is deprecated errors, so after some googling, replaced it with preg_match but i am stuck with errors   Code:   preg_match("^ and", "", $mid_str)   Error: Warning: preg_match(): No ending delimiter '^' found   Tried the following method but not working   preg_match("/^ and/", "", $mid_str)   Can you guys help me with correct code?   Thanks for looking.  

Hi, I have a "scraped" string and want to use the preg_match() to give me just a pice of it. The string is from a webpage, but is dynamic....   here´s the typical string format:   <a class="stripped-link lightblue-link profile-page-link" href="/x/xxx+xxx+xxx/xxxx">HER IS THE WANTED TEXT</a>   The orange is static. The green (the xxxx is the dynamic part of the string) Can I use the preg_match() for this?   thanks (and yes I´m a newbe.... )

Im trying to match this string, but i dont wat to match normal words like "hello world 646"

Code: [Select]
$string = "2ab055843241f20044af82ae0d5ace04"; //always over 15 chars - without spaces

if ( preg_match('~^[0-9\s]+$~D', $string)) {
echo 'yes';
}
If i can do it with preg_match that would be great

I know $regex_pattern is wrong but I need a solution to find a content between <body> and </body>.

Code: [Select]
<?php
$content = "<html><head><title>Your IP</title></head><body>Your IP Address: 63.1.142.154</body></html>";
$regex_pattern = "/<body>(.*)<\/body>/";
$preg_match($regex_pattern,htmlspecialchars($content),$matches);
print_r( $matches );

How to a check if a php variable value is one of the following characters: A to J, or ,k to t, (ie.: A B C D E F G H I J k l m n o p q r s t)   I tried:

if (preg_match[A-Jk-t], $checkChar) 
{   
// do this
}

 

I'm pretty new to this, How exactly could i get the text between the www. and .com?

so if i have a url:

http://www.facebook.com

I want to just return  "facebook"

in my site search some of the results come out still with html. i have used the strip tags function but how would i use the preg_match function to get rid of the "> still left over?

Hi guys,
I have been using this code:
preg_match('/<h2>(.*?)<\/h2>/', $data, $matches);

which i changed to:
$tag1 = 'h2';
$tag2 = 'h2';
preg_match('/$tag1(.*?)$tag2/', $data, $matches);

however i need it to work allowing variables (of any character or symbol) within $tag1.
I tried
$tag1 = 'h(.*?)2';
$tag2 = 'h2';
preg_match('/$tag1(.*?)$tag2/', $data, $matches);

but that does not work ....

essentiall the whole thing would work like this (example only):
firstpartoftag1VARIABLE1lastpartoftag1VARIABLE2tag2

ps the preg_match should only capture the VARIABLE2 data not VARIABLE1

any ideas or help would be much appreciated

cheers in advance
