PHP preg_replace three times with three different patterns? right or wrong?

Question

A simple question: Is this the best way to do it?

$pattern1 = \"regexp1\";
$pattern2 = \"regexp2\";
$pattern3 = \"regexp3\";

$content = preg_replace($patter         


        

Answer 1

To do multiple searches in a single preg_replace() call, use an array of patterns. You can still pass a single replacement, this is what's matched by all three patterns is replaced with:

$content = preg_replace(array($pattern1, $pattern2, $pattern3), '', $content);
