Access key and value from an array of objects

  • Hi I am trying to loop through an array of objects that looks like this 

    $categories = array(
[0]=> { feature: 'accounting' },
[1]=> { industry : 'service'}
);

$categories_copy = [];

foreach ($categories as $key => $value) {
		
		array_push($categories_copy, $value);
		
	}

    When I try to push it, the $value is the whole { feature : ‘accounting’ } and the $key is just 0, 1 ….

    Is there a better way to loop through it so I can access the key/value pair as $key being feature and $value being ‘accounting’. Looking to get this dynamically cause the key’s may change

  • The value of $value in your example is the object itself, not the value of the objects data.

    If you are 100% sure that your objects will only have one value available like that you can try something like this:

    foreach ($categories as $i => $object) {
    $values = get_object_vars ($object);

    foreach ($values as $key => $val) {
        array_push ($categories_copy, $val);
    }
}

    However, if you’re going to ever have more than one value in each object you’re going to have to figure out which value you want to get. That will be a bit more difficult as the keys for your objects seem to change as per your example.

    Ahh that didn’t work, I keep getting a critical error when trying it

    So what is the error message? Some basic debugging will help you to find out what is wrong.
