<?php
echo strcmp("Hello world!","Hello world!");

SO you want something like this?
Text1: Hello World
Text2: Hi words are my music
Hits: H,e,o,r,d
Do you need case-sensitivity or extended characters?

yes i want this with case sensitivity
diafol
$text1 = "Hello this is!!! my time";
$text2 = "ThiHs is unbelievables";
$r1 = str_split(preg_replace("/[^a-zA-z]/","",$text1)); //make array of alphabetical chars only
$r2 = str_split(preg_replace("/[^a-zA-z]/","",$text2)); //ditto
$hits =array_unique(array_intersect($r1,$r2)); //get an array of common chars
sort($hits); //sort chars
$hits = implode(", ",$hits); //create a comma delimited list of chars
echo "Matches for \"$text1\" and \"$text2\" are: $hits"; //echo outputMaybe an easier method though.
