str_replace help

[project3]

I have a string and want to repace the first 14 digits with x's how would I go about doing that?

[kenrbnsn]

I would use a combination of the substr() and str_replace() functions:

<?php
$str = "this is a very long string that is longer that 14 characters long";
$x = 'xxxxxxxxxxxxxx';
$new_str = str_replace(substr($str,0,14),$x,$str);
echo $str . '<br>' . $new_str;
?>
