PHP - Type Handling

What will be the output of this PHP code?

$a = 0;
$b = '0';
if ($a === $b) { echo 'Equal'; } else { echo 'Not Equal'; }

ANot Equal

BEqual

CError

DNo output

Step-by-Step Solution

Solution:

Step 1: Understand strict comparison with 0 and '0'
Strict comparison checks type and value; integer 0 and string '0' differ in type.
Step 2: Evaluate if condition
Since types differ, condition is false, so echo 'Not Equal' executes.
Final Answer:
Not Equal -> Option A
Quick Check:
0 === '0' is false [OK]

Quick Trick: === checks type, so 0 !== '0' [OK]
