Are there specific functions or methods in PHP that are recommended for type-safe comparisons?

When comparing values in PHP, it's important to use type-safe comparison operators to ensure that both the value and the type match. This helps prevent unexpected behavior that can occur with loose comparisons. The recommended type-safe comparison operators in PHP are === (identical) and !== (not identical). 

$value1 = 5;
$value2 = '5';

// Type-safe comparison using ===
if ($value1 === $value2) {
    echo "Values are identical.";
} else {
    echo "Values are not identical.";
}
