    Hi,
    I need a function to replace anything that is not "alphanumeric" to a _ sign in a string.
    $str= "this is my text!";
    output can be: "This_is_my_text_";
    Please give me a function to do this...
    Thanks :)

    I don't know if it's 100% reliable, but you could try this:

    
$str= "this is my text!";

$result = preg_replace('/[^A-Za-z0-9]/', "_", $str);

echo $result;
