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?
You are assigning $count to 0 in your conditional statement
Instead of...
if ($count = 0)
Do this
if ($count === 0)
Whenever you are going to check one logic means, check twice if we are using correct operators.
Most of them doing the same mistake like ,
if ($count = 0) // here you are assigning the value to $count variable
Assign the values instead of compare the values.
if ($count == 0) // here variable is compared
We can use more operators for comparing the logical condition.Such like ( >, <, >=, <=, == )
