What changes were suggested to the original code to address the issue?

Issue: The original code is using the `==` operator for comparison, which can lead to unexpected results due to type coercion. To address this issue, we should use the `===` operator, which checks for both value and type equality. Updated code snippet:

if ($var1 === $var2) {
    // Code to execute if $var1 is strictly equal to $var2
} else {
    // Code to execute if $var1 is not strictly equal to $var2
}
