//users post example
$post = 'fb.com/sometext';

//here we remove what we dont want
//str_replace('THE TEXT YOU DONT WANT', 'TEXT YOU DO WANT(OR)LEAVE BLANK', $post);
$post = str_replace('fb.com/', '', $post);

//here we show new result which should display
//sometext
echo $post;
//

<?php
$var = parse_url("http://fb.com/xxx?q=pov");

print_r($var); // Array ( [scheme] => http [host] => fb.com [path] => /xxx [query] => q=pov )

2) what if u want to get the last 3 letters of a word, eg "GHOST" and i want to get only the "OST" and/or the first 2 words also eg "GH"

I think this is just the thing u wanted: PHP.NET Function Substr

<?php
$rest = substr("ghost", -1);    // returns "t"
$rest = substr("ghost", -2);    // returns "st"
$rest = substr("ghost", -3, 1); // returns "o"
?>
