handling empty string returned from JS to a PHP array

Hi all !

What would be the best way to identify and handle an empty array sent from JS to PHP? This rather simple looking problem has resulted in a lot of confusion to me. 

$_POST['myArray'] = "";               // an empty string -- this is how the empty array from JS is received in PHP


Thanks !

Hi Kicken !

Thanks for the response. I have done something like what you are suggesting and it works. However I was wondering, since it would be a common issue with AJAx calls, that there would be maybe a "proper" way of handling blank strings that need to be interpreted as arrays on php side of things. 

Though my code works but does seem a bit of a hack.

Thanks again.

Send JSON. Even empty arrays are still identifiable as arrays.
