Regular expression to remove comments from SQL statement

Question

I\'m trying to come up with a regular expression to remove comments from an SQL statement.

This regex almost works:

(/\\*([^*]|[\\r\\n]|(\\*+([^*/]|         


        

Answer 1

This code works for me:

function strip_sqlcomment ($string = '') {
    $RXSQLComments = '@(--[^\r\n]*)|(\#[^\r\n]*)|(/\*[\w\W]*?(?=\*/)\*/)@ms';
    return (($string == '') ?  '' : preg_replace( $RXSQLComments, '', $string ));
}

with a little regex tweak it could be used to strip comments in any language
