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

As you are replacing all with the same, you could do either pass an array

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

or create one expression:

$content = preg_replace('/regexp1|regexp2|regexp3/', '', $content);

If the "expressions" are actually pure character strings, use str_replace instead.
