Remove the following element

$value['#434434*siva']

Can you be some more clear, want the array keys with special characters removed? — Thamilhan, Dec 01 '15 at 05:17

`preg_replace('/[^a-z0-9]*/i', '', '#434434*siva')` if you only want to keep the alpha-numeric chars — i--, Dec 01 '15 at 05:31

You can use preg_replace('/[^A-Za-z0-9\-]/', '', $string) to remove all the special characters

<?php
    function clean($string) 
    {
        return preg_replace('/[^A-Za-z0-9\-]/', '', $string); // Removes special chars.
    }
?>

Then for array, you can do it like:

<?php
    foreach($value as $val)
        clean($val);
?>
