"Note: As of PHP 5.0.0 the number of matched and replaced needles (search) will be returned in
count which is passed by reference. Prior to PHP 5.0.0 this parameter is not available."
In version 4.3.10 and I assume others before 5.0.0, str_replace returns null if you pass it a
$count.
<?php
$count = 0;
$str = "This is a string";
$str = str_replace("a", "a null", $str, $count);
if (is_null($str)) { // TRUE before php 5.0.0
echo "NULL";
}
?>
Fortunately, this does produce a warning: "Wrong parameter count for str_replace()"
