How to Fix the \"Notice: Trying to Get Property of Non-Object\" Error When Accessing API Data?

"Notice: Trying to Get Property of Non-Object" Error: Insight and Resolution

When attempting to retrieve data from the API at "http://api.convoytrucking.net/api.php?api_key=public&show=player&player_name=Mick_Gibson," you may encounter the "Notice: Trying to get property of non-object" error when using the following code:

<?  
$js = file_get_contents('http://api.convoytrucking.net/api.php?api_key=public&show=player&player_name=Mick_Gibson');
$pjs = json_decode($js);
var_dump($pjs->{'player_name'});
?>

Cause of the Error:

This error occurs because $pjs is an array containing a single object, rather than the expected object itself. Line 9 of your code attempts to access a property (player_name) of $pjs directly, which is an array, not an object.

Solution:

To resolve this issue, first access the array element that contains the object ($pjs[0]) and then access the desired object attribute:

echo $pjs[0]->player_name;

Detailed Explanation:

The result of var_dump($pjs) reveals that $pjs is an array with a single element, which is an object containing various player data. To access the player_name property, you first need to specify the array index (in this case, 0) and then access the desired property of the resulting object.

By updating your code to the following, you will correctly retrieve the player_name property:

echo $pjs[0]->player_name;
