foreach is slow?

[garcon]

<?php
$rules_list = explode("*",$venue->rules); 
echo "<ul class=\"venue_rules\">";
foreach($rules_list as &$rule) {
    echo "<li>$rule</li>";
}
echo "</ul>";
?>

 

This seems to be slow - the page takes a noticeable couple of seconds to load when testing it on my PC since I added it. I think maybe that is not the correct use of foreach and there's a quicker way to do the same thing? Can anyone point me in the right direction? Cheers.

what's with the & in front of $rule.

 

&$rule

Me being an idiot!

 

The examples in the php.net manual were modifying the array so it was a pointer.

 

I of course don't need this and it appears to have speeded things up a bit.

 

Cheers fella.
