Next Code

This function extracts all alpha numeric letters and numbers from a string. Basically, it takes out everything that is not an alpha-numeric character, including spaces.

This function is useful in taking out excess characters before inserting data into mysql, i.e. "-" for phone numbers.

function get_alpha($string) { $new_string = ereg_replace("[^A-Za-z0-9]", "", $string); return $new_string; } <a target="_blank" href="http://www.phpfreecode.com/">PHP Free Code</a>
