I'm not sure if this is even possible, but I think I've seen something like it so I hope it is.

I want to use PHP to search a websites source page and retrieve anything like this for example: topic=* (where * is a wildcard), then list all the results its found. How could I go about doing this?

Any help is appreciated and if needed I'll try to explain it better.

Will * be inside of quotes, like topic="hello"?

If not, your wild card * starts after the = sign, but where does it end?

Your going to need something like this http://au3.php.net/curl to get the pages, and regular expressions to find what you want on it. I this would return an array of what I think you want.

preg_match('`topic="([^\"]*)"`',$pageText);

Thanks, but I still don't quite understand what to do here, sorry! Could you give me an example of how to do it, I've been testing around with it but can't get it to work.

mpfeif101, yes, it'll be inside quote like "topic=*".

Ok hows this then

$url = "http://example.com/";
$ch = curl_init();
$timeout = 2; // set to zero for no timeout
curl_setopt ($ch, CURLOPT_URL, $urll);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$content = @curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);

if($info['http_code'] == '200') {
$topic = preg_match('`topic="([^\"]*)"`',$content);
print_r($topic);
}

Ok, just tried it out, just shows 0 on the page.

Here's what I got:

$url = "http://example.com/";
$ch = curl_init();
$timeout = 2; // set to zero for no timeout
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$content = @curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);

if($info['http_code'] == '200') {
$topic = preg_match('`http://example.com/topic="([^\"]*)"`',$content);
print_r($topic);
}

Any ideas?

[Michael]

You just might want to change this

$url = "http://example.com/";

[Tigger93]

Yes, I did. I was just using that as an example for the website.

[Michael]

$topic = preg_match('`http://example.com/topic=(.*)`',$content);

Try that regular expression.

[Tigger93]

Nope. Still just shows 0 on the page.

[Michael]

What page are you useing, so I can test it?

I should sleep more, my brain is not working right

[codebox]
<?php

$url = "http://example.com/";
$ch = curl_init();
$timeout = 2; // set to zero for no timeout
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$content = @curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);

if($info['http_code'] == '200') {
$topic = preg_match_all('`http://example.com/topic=(.*)\n?"?`',$content,$matches);
print_r($matches[1]);
}

?>
[/codebox]

Closer it looks like. Now it says Array ( ). Thanks for all the help so far.

[Michael]

What value are you useing for $url = "http://example.com/"; ?
