so I use file_get_contents to get the contents of a webpage, one of the lines has


Code: [Select]
<meta property="og:url" content="http://www.google.com/blahblahblah?s=5cd04d4a7632296b9cdb463d04e82c05" />
I want it to echo only http://www.google.com/blahblahblah so anything between <meta property="og:url" content=" and ?s=5cd04d4a7632296b9cdb463d04e82c05" /> I want to extract and put into a variable

this works just fine but I was thinking preg match would be better


$thread = explode('<meta property="og:url" content="', $psuc);
$thread = explode('?s=', $thread[1]);
echo $thread[0];


Thanks

basically what i am trying to do is replace the

<a href="whatever.com"> 

with

<a href="whatever.com" onclick = "if (! confirm("Continue?")) return false;">

so that when the user clicks the url in a message the box pops up first then redirects them to the url if they click confirm. However i am getting the following error:

Code: [Select]
Warning: preg_replace() [function.preg-replace]: Compilation failed: reference to non-existent subpattern at offset 11
here is the code i used.

$message_content = $content_info['message_content'];
$pattern='<a href="\\1">';
$replace='<a href="\\1" onclick = "if (! confirm("Continue?")) return false;">';
$message_content = preg_replace($pattern, $replace, $message_content);
echo $message_content;

Anyone know where i went wrong?

Hi,

Say you had, <business_name type="string">L Choong</business_name>, contained inside a variable(content before and after this in the same var), how would you extract the 'L Choong' information as a new var?

Thanks

im having trouble using this function. im trying to change the strings within a post.

eg:

Code: [Select]
This is an example post
[attachment=file.png]

what im trying to do is change [attachment=file.png] to file.png.

Here is the code i have but it doesnt change anything.


$p_content = str_replace('<br>', '', $post_info[$key]['p_content']);
        $attach = preg_split('|\[attachment=|', $p_content);
        
        for($i=0; $i<count($attach); $i++)
        {
            $attach[$i] = str_replace(']', '', $attach[$i]);
            if(file_exists($config['asf_root'].'attachments/'.$attach[$i]))
            {
                $p_content = preg_replace('|\[attachment=([0-9a-zA-Z\.-_])\]|#i', $attach[$i], $p_content);
            }
        }
        echo $p_content;


it first gets all the attachment tags within the post then applies the preg replace to all of them. But the preg replace isnt replacing, so i must have gone wrong somewhere.
Any tips/ideas?

Thanks

Hello,

I come from a C and PERL background.

I seem to have trouble finding how to do this easily.  What is the PERL equivalent of:

$var =~ s/^\+//g;    // remove a plus from the beginning, and from the entire string.

Thanks.

Hello,
I am trying to crawl a website and get all the domain names listed on the site to output into my php script. 
I am using the following code.... 
The main area is the preg match area, since I know nothing about it, nor do I understand it a little bit!

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"http://link I am getting data from.com);
curl_setopt($ch, CURLOPT_TIMEOUT, 30); //timeout after 30 seconds
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
$result=curl_exec ($ch);
curl_close ($ch);
// Search The Results From The Starting Site
if( $result )
{
// LOOKING FOR ANYTHING.COM  all .com's
preg_match_all( "(.*)\.com", $result, $output, PREG_SET_ORDER );
 
foreach( $output as $item )

{
// ALL LINKS DISPLAY HERE 
print_r($item);



}

}


Any help would be greatly appreciated!

So i have this script  that outputs Listed Files inside a folder

    echo '<option value="'.$fileName.'">'.$fileName.'</option>';}

like this :

<option value="Fonts/28 Days Later.ttf">Fonts/28 Days Later.ttf</option> etc files ....

i would like to know how may i remove  " Fonts/ " And the .ttf extension from the second part that repeats (the name) using something like preg_replace and to make the first letter uppercase using ucfirst()


And if someone is familiar with preg_replace
could you please give me a tutorial on how it works to replace some text ?

Thanks In Advance

$name = preg_replace('{(\d+)}', convertNumber("$1"), $row['name']); 


why isnt this working?

Hello, I am trying to replace a url and add a sub-id to it, however I'm not quite there. Any help is always appreciated here. In the end, I would like the value of gotoUrl to have the cpId 123abc45 attached to it. I.E.

http://example.com/?Aff=56732&SID=123abc45
http://example.com/?Aff=56732&uv=123abc45&product=1834234
http://example.com/?Aff=56732&cid=123abc45&ace=2gs244s3

$gotoUrl = "http://example.com/?Aff=56732&SID=";
// OR could be listed as such:
// $gotoUrl = "http://example.com/?Aff=56732&uv=default&product=1834234";
// $gotoUrl = "http://example.com/?Aff=56732&cid=&ace=2gs244s3";

// Will attach this to replace value
$cpId = "123abc45";
// Possible sid replacements, depending on the url
$sidList = array("sid","SID","cid","uv");

	if ($gotoUrl){
		foreach($sidList as $sidVar){
			if (preg_match("/$sidVar/i", $gotoUrl)){
			$gotoUrl = preg_replace("#{$sidVar}(?=.*\d)(?=.*[a-z])(?=.*[A-Z])$#", "{$sidVar}={$cpId}", $gotoUrl);
			}
		}
        echo $gotoUrl;
        }
