PHP Fatal error: Cannot use object of type stdClass as array in error

PHP Fatal error: Cannot use object of type stdClass as array in error

Let's take a look at the solution to the php Fatal error: Cannot use object of type stdClass as array in during PHP development.

The following error occurs in a common array:

The Code is as follows:
<? Php Array ( [0] => stdClass Object ( [Id] => 1 [Title] => excellent recommendations [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) ) ?>

Later, Baidu searched for a similar question, but the other side was json data.

When php calls json_decode to generate a json object from a string object, if the [] operator is used to retrieve data, the following error is returned:

Cannot use object of type stdClass as array

Cause:

The Code is as follows:
$ Res = json_decode ($ res ); $ Res ['key']; // use the object after json_decode () as an array.

Solution (2 types ):

1. Use json_decode ($ d, true ). The second variable of json_decode is set to true.

2. json_decode ($ res) returns an object. You cannot use $ res ['key'] for access. You can replace it with $ res-> key.

Now let's go back to our original issue and find out

It turns out that [] cannot be directly used for display. The output of the above Code is: $ pic [0] [title], changed to $ pic [0]-> title, which is normal.
