How to Fix the \'Notice: Trying to get property of non-object\' Error in PHP: Convoy API Example

Understanding the "Notice: Trying to get property of non-object" Error

In PHP, when trying to access a property of a non-object, the "Notice: Trying to get property of non-object" error is thrown. This error occurs because PHP expects you to access properties only from objects or arrays, while in this case, it encounters a non-object variable.

Resolving the Error in the Convoy API Example

The provided code attempts to retrieve data from the Convoy API and access the "player_name" variable from the response. However, the response is an array of objects, not a standalone object. To resolve the error, you need to access the array element first and then the object's attributes.

<code class="php">$pjs = json_decode($js, true); // Decode JSON as an array
echo $pjs[0]['player_name']; // Access "player_name" from the first element (array key 0)</code>

Understanding the Array Structure

The $pjs variable contains an array with a single element, which is an object. As the response represents a player's details, the object has various attributes related to the player's information.

Dumping the Response

The var_dump($pjs) statement displays the data structure of the response. It reveals that $pjs is an array with one element. The element is an object with the following attributes:

• player_name: String representing the player's name
• player_id: Integer representing the player's ID
• rank: String representing the player's rank
• lastseen: Integer indicating the player's last seen timestamp
• registration_date: String representing the player's registration date
• Other attributes related to the player's statistics and achievements

By understanding the data structure, you can effectively access the desired property without encountering the "Notice: Trying to get property of non-object" error.
