You probably also don't want * and %.
You can also make use of prepared statements or stored procedures
against SQL Injection.

hi everyone!

i was just wondering if this filter function written in php is safe against
sql injections:

function filter($string) {
  $replace = "";
  $search = array(">", "<", "|", ";");
  $result = mysql_escape_string( str_replace($search, $replace, $string));
  return $result;
}

or could anyone imagine an sql injection attack which bypasses this filter
function?
