There's another function that can be used if you want to replace only
one sub string, substr_replace(). See
<http://www.php.net/substr_replace>

Example:

<?
$str = 'john goes running and then goes to the store';
echo 'Original string: ' . $str . '<br>';
echo 'Using str_replace: ' .
str_replace(substr($str,4,5),'',$str).'<br>';
echo 'Using substr_replace: ' . substr_replace($str,'',4,5);
?>

Results:

Original string: john goes running and then goes to the store
Using str_replace: john running and then to the store
Using substr_replace: john running and then goes to the store
