<?php
class proxy extends MysqlndUhConnection {
public function escapeString($res, $string) {
printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true));
$ret = parent::escapeString($res, $string);
printf("%s returns %s\n", __METHOD__, var_export($ret, true));
return $ret;
}
}
mysqlnd_uh_set_connection_proxy(new proxy());
$mysqli = new mysqli("localhost", "root", "", "test");
$mysqli->set_charset("latin1");
$mysqli->real_escape_string("test0'test");
?>
以上例程会输出：
proxy::escapeString(array ( 0 => NULL, 1 => 'test0\'test', )) proxy::escapeString returns 'test0\\\'test'
