Example #1 MysqlndUhConnection::useResult() example
<?php
class proxy extends MysqlndUhConnection {
public function useResult ( $res ) {
printf ( "%s(%s)\n" , __METHOD__ , var_export ( func_get_args (), true ));
$ret = parent :: useResult ( $res );
printf ( "%s returns %s\n" , __METHOD__ , var_export ( $ret , true ));
var_dump ( $ret );
return $ret ;
}
}
mysqlnd_uh_set_connection_proxy (new proxy ());
$mysqli = new mysqli ( "localhost" , "root" , "" , "test" );
$mysqli -> real_query ( "SELECT 'Good morning!' AS _msg FROM DUAL" );
$res = $mysqli -> use_result ();
var_dump ( $res -> fetch_assoc ());
?>
以上例程会输出:
proxy::useResult(array ( 0 => NULL, )) proxy::useResult returns NULL resource(425) of type (Mysqlnd Resultset (internal only - you must not modify it!)) array(1) { ["_msg"]=> string(13) "Good morning!" }
