Question

What I started with:

foreach($a as $b){if($b=='')return 0;}return 1;  // works but verbose

My second attempt:

return (in_array('',$a)+0); // returns the opposite of what I need

What I am currently using:

return in_array('',$a)?'0':'1';

using a cast per JRL (shortest)

return (int)!in_array('',$a);

I assume this is the best way to do this, but just wanted to validate. Is this the best way to test for an empty value in an array?

I am aware that this tests for 0,NULL,FALSE or an empty string and that is O.K.

Answer 1

Other alternative:

return (int)!in_array('', $a));
