preg_replace在数组php中

Question

$search = array("<?php", "god", "gOd"); //do not want to do this in so many words\\
$replace = array("<-php", "God", "God");
$comment = str_replace($search, $replace, mysqli_real_escape_string($conexao, $_POST['comment']));

I want to include uppercase and lowercase letters in the array, how to do this for $search and $replace?

If you have to use regular expressions, write your code like this:

preg_replace('/regular expression here/i', 'replacement here', $string);

Otherwise use str_ireplace(): http://php.net/manual/en/function.str-ireplace.php
