Example #1 MysqlndUhConnection::changeUser() example
<?php
class proxy extends MysqlndUhConnection {
public function changeUser ( $res , $user , $passwd , $db , $silent , $passwd_len ) {
printf ( "%s(%s)\n" , __METHOD__ , var_export ( func_get_args (), true ));
$ret = parent :: changeUser ( $res , $user , $passwd , $db , $silent , $passwd_len );
printf ( "%s returns %s\n" , __METHOD__ , var_export ( $ret , true ));
return $ret ;
}
}
mysqlnd_uh_set_connection_proxy (new proxy ());
$mysqli = new mysqli ( "localhost" , "root" , "" , "test" );
var_dump ( $mysqli -> change_user ( "root" , "bar" , "test" ));
?>
以上例程会输出:
proxy::changeUser(array ( 0 => NULL, 1 => 'root', 2 => 'bar', 3 => 'test', 4 => false, 5 => 3, )) proxy::changeUser returns false bool(false)
