PHP Count Array Elements

Question

hi can someone explain why this would return "An array consists of 0 elements." :

$arr = array(1,3,5); 
$count = count($arr); 
if ($count = 0) { echo "An array is empty."; } else { echo "An array has $count elements."; }

By the way, this is one a quiz i'm working through and i'm not sure why this is the correct answer?

Solution

You are assigning $count to 0 in your conditional statement

Instead of...

if ($count = 0)

Do this

if ($count === 0)
