Example #1 MysqlndUhConnection::getErrorNumber() example
<?php
class proxy extends MysqlndUhConnection {
public function getErrorNumber($res) {
printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true));
$ret = parent::getErrorNumber($res);
printf("%s returns %s\n", __METHOD__, var_export($ret, true));
return $ret;
}
}
mysqlnd_uh_set_connection_proxy(new proxy());
printf("connect...\n");
$mysqli = new mysqli("localhost", "root", "", "test");
printf("query...\n");
$mysqli->query("PLEASE_LET_THIS_BE_INVALID_SQL");
printf("errno...\n");
var_dump($mysqli->errno);
printf("close...\n");
$mysqli->close();
?>
The above example will output:
connect... proxy::getErrorNumber(array ( 0 => NULL, )) proxy::getErrorNumber returns 0 query... errno... proxy::getErrorNumber(array ( 0 => NULL, )) proxy::getErrorNumber returns 1064 int(1064) close...
