private function bindVars( $stmt , $params ) { if ( $params != null) { $types = '' ; //initial sting with types foreach ( $params as $param ) { //for each element, determine type and add if ( is_int ( $param )) { $types .= 'i' ; //integer } elseif ( is_float ( $param )) { $types .= 'd' ; //double } elseif ( is_string ( $param )) { $types .= 's' ; //string } else { $types .= 'b' ; //blob and unknown } } $bind_names [] = $types ; //first param needed is the type string // eg: 'issss' for ( $i =0; $i < count ( $params ); $i ++) { //go through incoming params and added em to array $bind_name = 'bind' . $i ; //give them an arbitrary name $ $bind_name = $params [ $i ]; //add the parameter to the variable variable $bind_names [] = &$ $bind_name ; //now associate the variable as an element in an array } //call the function bind_param with dynamic params call_user_func_array( array ( $stmt , 'bind_param' ), $bind_names ); } return $stmt ; //return the bound statement |
