    `$newstring = substr('009715012345', -7);` or `$newstring = substr('+97105012345', -7);` or `$newstring = substr('97105012345', -7);` same function for all requirements – Nishant Solanki Mar 19 '15 at 12:36

    Secondly, you already laid it out in pseudo code, you know what to do. Throw in some if statements (http://php.net/manual/en/control-structures.if.php) and you should be golden. What do you need from SO, this website is not a replacement for documentation, practice and trying? – Nico Mar 19 '15 at 12:38

You need to use preg_replace function.

$re = "/^(?:(?:\\+|00)971|9710)/m";
$str = "009715012345\n+9715012345\n97105012345";
$subst = "";
$result = preg_replace($re, $subst, $str);
echo $result;
