Example #1 MysqlndUhConnection::query() example
<?php
class proxy extends MysqlndUhConnection {
public function query($res, $query) {
printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true));
$query = "SELECT 'How about query rewriting?'";
$ret = parent::query($res, $query);
printf("%s returns %s\n", __METHOD__, var_export($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());
?>
以上例程会输出：
proxy::query(array (
0 => NULL,
1 => 'SELECT \'Welcome mysqlnd_uh!\' FROM DUAL',
))
proxy::query returns true
array(1) {
["How about query rewriting?"]=>
string(26) "How about query rewriting?"
}
