get rid of excess code

[dreamwest]

Im trying to break apart a group of hyperlinks so im just left with the actual url:

 

html here<a class='link' href='http://www.site.com/?q=6J4W2G4fASI'>html here

html here<a class='link' href='http://www.site.com/?q=637yfuhqelhe'>html here

html here<a class='link' href='http://www.site.com/?q=hilghye8oyhi'>html here

etc...

 

so the result would be :

 

http://www.site.com/?q=6J4W2G4fASI

http://www.site.com/?q=637yfuhqelhe

http://www.site.com/?q=hilghye8oyhi

Do you mean you are trying to strip the links out of an existing HTML document?

[dreamwest]

yes

You can grab the URLs with regex:

 

<?php
$str = "html here<a class='link' href='http://www.site.com/?q=6J4W2G4fASI'>html here
html here<a class='link' href='http://www.site.com/?q=637yfuhqelhe'>html here
html here<a class='link' href='http://www.site.com/?q=hilghye8oyhi'>html here";
preg_match_all('~<a\b[^>]+href\s?=\s?[\'"](.*?)[\'"]~is', $str, $matches);
echo '<pre>' . print_r($matches[1], true) . '</pre>';
?>

 

Note that $matches[1] will be an array of the URLs.

 

Or alternatively use PHP DOM:

 

<?php
$urls = array();
$str = "html here<a class='link' href='http://www.site.com/?q=6J4W2G4fASI'>html here
html here<a class='link' href='http://www.site.com/?q=637yfuhqelhe'>html here
html here<a class='link' href='http://www.site.com/?q=hilghye8oyhi'>html here";
$dom = new DOMDocument();
$dom->loadHTML($str);
$tags = $dom->getElementsByTagName('a');
foreach ($tags as $tag) {
$urls[] = $tag->getAttribute('href');
}
echo '<pre>' . print_r($urls, true) . '</pre>';
?>

html here<a class='link' href='http://www.site.com/?q=hilghye8oyhi'>html here";

Sweet thanks!

 

I knew preg_match_all would do it but couldnt get my head around the regex

[dreamwest]

By the way which is faster, regex or php dom??

You most likely won't notice the difference either way, but my knowledge over the topic isn't very expansive. However, these guys seem to know what they're talking about.

PHP DOM is sweet. I like not having to need regex, and the OOP involved makes things more clear because my brain is in full OOP mode.
