PHP array_key_exists not working

Question

I have a PHP array that looks like this if I print_r($myarray)

Array ( [0] => Array ( [description] => testdecr [link] => testlink [image_id] => 150 ) )

I am trying to check for a key called image_id by doing this...

if (array_key_exists("image_id",$myarray)) {
        echo 'Image_id exists';
    }

This is not working, anyone any ideas what I am doing wrong?

"image_id" key is on nested array under position 0.
It should be:

...
if (array_key_exists("image_id", $myarray[0]))

Thank you, makes sense now. Could it be modified so that it wouldn't matter how many levels there are? – fightstarr20 Jun 29 '17 at 21:38
@fightstarr20, welcome. Yes, it can be modified to check if `image_id` key exists on any array level, but it sounds like new input condition – RomanPerekhrest Jun 29 '17 at 21:41
