How can explicit type-safe comparisons in PHP code enhance readability and aid in debugging?

Explicit type-safe comparisons in PHP code enhance readability and aid in debugging by ensuring that the variables being compared are of the same type before performing the comparison. This helps prevent unexpected type coercion that can lead to bugs in the code. By explicitly specifying the type in comparisons, it becomes easier to understand the code and track down any issues related to type mismatches.

// Type-safe comparison example
if ($var1 === $var2) {
    // Code block
}
