PHP Filename Friendly Function

PHP Filename Friendly Function

This function outputs a string that is filename friendly. It removes all non-characters and punctuation from the input and converts to lowercase. I find this useful for seo friendly cms pages. This function is still being tweaked so any improvements would be most appreciated.


function checkCharacters($title) {
	$final_text = ”;
	$title = strtolower(trim(stripslashes($title)));
	for ($i = 0; $i < strlen($title); $i++) {
		$letter = substr($title,$i,1); 
		$ascii = ord($letter); 
		if (($ascii >= 97 && $ascii <= 122) || ($ascii>=48 && $ascii <= 57))
		{
			$final_text .= $letter; 
		}
		else 
		{
			$final_text .= "-"; 
		}

	return $final_text;
}
