What improvements could be made to the PHP code to optimize performance or readability?

Issue: One improvement that could be made to optimize performance in PHP code is to use the strict comparison operator (===) instead of the loose comparison operator (==) when comparing values. This ensures that not only the values are equal but also their types are the same, which can prevent unexpected behavior and improve code reliability. Code snippet:

// Before
if ($variable == 1) {
    // Do something
}

// After
if ($variable === 1) {
    // Do something
}
