PHP Code:

 //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;

//

maybe this will help

PHP Code:

 <?php

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

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

PHP Code:

 <?php

$rest = substr("ghost", -1);    // returns "t"

$rest = substr("ghost", -2);    // returns "st"

$rest = substr("ghost", -3, 1); // returns "o"

?>
