How to check if MongoDB error?

Question

How can I check to see if there was an error with MongoDB?

var_dump($mongodb->lastError());

gives me a blank page.

Are you using `echo` or `var_dump`? Can we see your full code? — SomeKittens, Oct 18 '12 at 22:49

Mongo::lastError — Check if there was an error on the most recent db operation performed

Deprecated

// NOT WORK!!
$mongo = new Mongo();
var_dump($mongo->lastError());

You only see a blank page because you have error reporting turned off in your PHP configuration.

MongoDB::lastError — Check if there was an error on the most recent db operation performed

You need MongoDB class

// WORK!!
$mongo = new Mongo();
$db    = $mongo->database;
var_dump($db->lastError());

$mongo = new Mongo(); $db = $mongo->database; var_dump($mongo->lastError()); – Oct 18 '12 at 23:30
`$mongo->lastError()` --> `$db->lastError()` – Wahyu Kristianto Oct 18 '12 at 23:34
Thank you :) it works array(4) { ["n"]=> int(0) ["connectionId"]=> int(4) ["err"]=> NULL ["ok"]=> float(1) } – Oct 18 '12 at 23:37
