Because the sql types could be combined it would be better to use a function like this:

function getMySQLType($str){
      $str=trim($str);
      return strtoupper(substr($str,0,strpos($str,' ')));     
}

$sql="select * from user;";
if (getMySQLType($sql) == 'SELECT'){
//true
}

WARNING : this function (or maybe the "enable_rpl_parse" function) randomly causes a segfault into PHP.
We don't use this function anymore. Instead we check if the query contains the word 'SELECT' :

function query_type($query)
{
    if ( stripos($query,'SELECT'))   
        return true;
    return false;
}
