PHP Compare 2 Arrays - array to string conversion error

Question

    foreach($this->galleryPhotoDBInitialArray as $initialArrayElement) {
        $photoExists = false;
         foreach($this->galleryPhotoDBFinalArray as $finalArrayElement) {
            if($initialArrayElement == $finalArrayElement) {
              $photoExists = true;
                echo $initialArrayElement;
            }
        }
        if(!$photoExists){
            echo 'delete............................................';
            echo $initialArrayElement;
        }
    }

I have the above code. I know the arrays have data as I can print_r() it and see the data. the Array data looks like this:

What do I need to do so I can access the $initialArrayElement value - I need to process this further but I get the PHP error 'array to string conversion error'...

thankyou very much :)

Answer 1

echo $initialArrayElement;

use print_r on this and check if this is still an array.. because at what i observe this was still an array..

Answer 2

Please use

print_r($initialArrayElement); insted of echo $initialArrayElement;

that will work.
