  • You want to set a value to every key you have in an array. If you want the value to be empty just set it "". Furthermore you want to give a , after every key => value in your array otherwise you will have even more Errors. Try those two steps pls and post again if you still have any errors. – Johannes Nov 02 '16 at 15:07
  • set $arr = Array(); before if loop – coder Nov 02 '16 at 15:11
  • `array_diff()` can't handle multidimensional arrays. – simon Nov 02 '16 at 15:15

This is because array_diff compares values after typecasting both compared values to string (see documentation notes).

Both of your arrays contain another array (ebay_user and second pictureUrl).

See this answer for recursive array_diff, which should work in your case.
