Beispiel #1 MysqlndUhConnection::queryReadResultsetHeader() example
<?php
class proxy extends MysqlndUhConnection {
public function queryReadResultsetHeader($res, $stmt) {
printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true));
$ret = parent::queryReadResultsetHeader($res, $stmt);
printf("%s returns %s\n", __METHOD__, var_export($ret, true));
return $ret;
}
}
mysqlnd_uh_set_connection_proxy(new proxy());
$mysqli = new mysqli("localhost", "root", "", "test");
$res = $mysqli->query("SELECT 'Welcome mysqlnd_uh!' FROM DUAL");
var_dump($res->fetch_assoc());
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
proxy::queryReadResultsetHeader(array (
0 => NULL,
1 => NULL,
))
proxy::queryReadResultsetHeader returns true
array(1) {
["Welcome mysqlnd_uh!"]=>
string(19) "Welcome mysqlnd_uh!"
}
