How to Fix the Uncaught Error "Cannot Use Object of Type stdClass as an Array"

The given snippet is dedicated to a common PHP issue "cannot use object of Type stdClass as an array".

Read on to learn how to fix this issue accurately.

A. Use json_decode

The function that we recommend you to use is <kbd class="highlighted">json_decode</kbd>.

This function is capable of returning an object by default.

Data may be accessed in the following way:

php access data

var_dump($result->context);

In the event of having identifiers such as, you should implement:

php identifier

var_dump($result->{'from-date'});

In case you intend to have an array, then run the code below:

php get array json_decode

$result = json_decode($json, true);

Alternatively, you can cast the object to an array like so:

cast object to array with json_decode

$result = (array) json_decode($json);

B. Accessing with ->

Let’s consider another solution with the -> sign.

So, access with the help of -> as it is an object.

Then, change the code from:

php change code with -> sign, from

$result['context'];

To:

php change code with -> sign, to

$result->context;

There you are.

Description of the stdClass in PHP

This is considered an empty class in PHP. It is applied for casting other types to the object. The <kbd class="highlighted">stdClass</kbd> has similarities with Python or Java objects.

You should take into consideration that stdClass is not the base class. Once an object is converted to an object, it is not changed. Yet, once an object type is converted to an instance of the <kbd class="highlighted">stdClass</kbd> generated, it is not NULL. Once it is NULL, the new instance will be empty.

The main use cases of the <kbd class="highlighted">stdClass</kbd> in PHP are:

• It directly accesses the members by calling them.
• It is handy for dynamic objects.
• It is used for setting dynamic properties, and so on.

About json_decode in PHP

The <kbd class="highlighted">json_decode</kbd> function is used for taking a JSON encoded string and converting it into a PHP variable.

It has four parameters: <kbd class="highlighted">json</kbd>, <kbd class="highlighted">assoc</kbd>, <kbd class="highlighted">depth</kbd>, and <kbd class="highlighted">options</kbd>.

Once the <kbd class="highlighted">assoc</kbd> parameter is TRUE, then the returned objects will be converted to associative arrays.
