Question

<li class="page_item page-item-6"><a href="http://localhost/wordpress1006/?page_id=6">About us</a></li> 
<li class="page_item page-item-12"><a href="http://localhost/wordpress1006/?page_id=12">Contact</a></li> 
<li class="page_item page-item-10"><a href="http://localhost/wordpress1006/?page_id=10">Portfolio</a></li> 
<li class="page_item page-item-8"><a href="http://localhost/wordpress1006/?page_id=8">Services</a></li> 

I need to pull links only from this list, I would use regular expressions but I’m too scared to try.
So numbers will change at the end of page_item page-item-number

what would you suggest me to do here?

Thanks in advance

Answer 1

Try this:

$matches = array();
$string = '
    <li class="page_item page-item-6"><a href="http://localhost/wordpress1006/?page_id=6">About us</a></li> 
    <li class="page_item page-item-12"><a href="http://localhost/wordpress1006/?page_id=12">Contact</a></li> 
    <li class="page_item page-item-10"><a href="http://localhost/wordpress1006/?page_id=10">Portfolio</a></li> 
    <li class="page_item page-item-8"><a href="http://localhost/wordpress1006/?page_id=8">Services</a></li> 
';
preg_match_all('/href="(.*?)"/i', $string, $matches);
var_dump($matches[1]);

Output:

array
  0 => string 'http://localhost/wordpress1006/?page_id=6' (length=41)
  1 => string 'http://localhost/wordpress1006/?page_id=12' (length=42)
  2 => string 'http://localhost/wordpress1006/?page_id=10' (length=42)
  3 => string 'http://localhost/wordpress1006/?page_id=8' (length=41)

(note it will fail on more complex HTML, in which case I would no longer use Regex, rather some thing like Simple HTML DOM)
