php函数在localhost中有效，但在服务器上不起作用

Question

When I try to put my website in production, i get an error, but everything works well in my wamp localhost.

The error =>

• Type: ErrorException
• Code: 8
• Message: Undefined offset: 0
• File: *******/httpdocs/alliance/slimrest/datamanager/dm_utilisateur.php
• Line: 20

Le line 20 is the last of this code portion =>

    $user = $o_utilisateur->getUserByLogPass($log, $pass);

    if(isset($user['0'])){
        //GET group BY user
        $tmp = $o_droit->getGroupById($user['0']['TB_groupe_id_groupe']);
        $user['0']['libele'] = $tmp['0']['libele'];

I might be the PHP version ?

• Localhost : PHP_VERSION = 5.5.12
• Server : PHP_VERSION = 5.5.9-1ubuntu4.4

Answer 1

You checked isset($user['0']) , but not isset($tmp['0']) . The problem must be with the $tmp variable, it has no 0 key.

if(isset($user['0']) && isset($tmp['0']))

I don't know what $tmp is supposed to contain, but for some reason it doesn't contain it on your production server. You need to check whatever code creates the $tmp array, perhaps it's a database problem, did you upload the DB to production?
