PHP Fatal Error:cannot Use object of type StdClass as array in error

Let's look at the solution to the problem of PHP Fatal error:cannot use object of type StdClass as array error in PHP development.

The following error occurred with the normal array

The code is as follows
<?php Array ( [0] => StdClass Object ( [ID] => 1 [Title] => Wonderful recommendation [Size] => 280*150 [pic] =>./uploadfiles/201402160422.jpg [State] => 0) [1] => StdClass Object ( [ID] => 2 [title] => Enterprise News [Size] => 280*150 [pic] =>./uploadfiles/201402160533.jpg [State] => 0) ) ?>

Then Baidu searched for a question about the same, but the other side was JSON data

When PHP calls Json_decode to generate a JSON object from a string object, if you use the [] operator to fetch the data, you get the following error:

Cannot use object of type StdClass as array

Causes:

The code is as follows
$res = Json_decode ($res); $res [' key ']; Use the object after Json_decode () as an array.

Solution (2 kinds):

1. Use Json_decode ($d, True). is to make the second variable of Json_decode set to true.

2, Json_decode ($res) Returns an object, can not use the $res [' key '] for access, replaced $res->key on it.

All right, now back to our original problem.

The original is not directly with [] to show the resulting, the above code output is used: $pic [0][title], changed to $pic[0]->title after normal
