PHP How to output the array content

Question

A function returns array of following type:

Array ( [0] => stdClass Object ( [post_id] => 48

I want to echo the array contents, so i tried using following foreach loop:

foreach ($posts as $post){
    echo $post['post_id'];
}

But I get following error:

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

The error message is quite clear: "Cannot use object [...] as array [...]". — Felix Kling

You have an array of objects. So, you need to change:

echo $post['post_id'];

To:

echo $post->post_id;

Now, you're printing the object property post_id.

If you're looking to output array or object information for something like debugging, you can do this:

echo '<pre>';
print_r($object);
echo '</pre>';

This should work for arrays or objects.

Also, I believe objects in PHP 5 have a "to_array" magic method that can convert an Object to an array of data.

I hope this helps!

If you want to output for debugging purpose, you could use print_r or var_dump which is more verbose about your object.
