difference between two strings in python/php
<p>I'm looking for an easy way to compare two similar strings and output the difference
for instance if I have</p>

<p>"abcdefghijklmnop"
and
"abcdefghi"</p>

<p>the function would output </p>

<p>"jklmnop"</p>

<p>I need to know how to do this in both php and python</p>
