What will be the output of this PHP code?

$a = 0;
$b = '0';
var_dump($a == $b);
var_dump($a === $b);

Abool(true) bool(false)

Bbool(false) bool(true)

Cbool(true) bool(true)

Dbool(false) bool(false)

Step-by-Step Solution

Solution:

Step 1: Evaluate loose comparison ($a == $b)
0 (int) and '0' (string) are equal after type conversion, so $a == $b is true.
Step 2: Evaluate strict comparison ($a === $b)
Types differ (int vs string), so $a === $b is false.
Final Answer:
bool(true) bool(false) -> Option A
Quick Check:
Loose == true, Strict === false [OK]

Quick Trick: Remember === checks type too, == converts types [OK]
