How do I inspect function arguments

Inspecting function arguments in PHP can help you understand what data is being passed to functions, allowing for better debugging and code optimization. This technique is particularly useful when functions have multiple parameters or when dealing with complex data structures.

    <?php
    function myFunction($arg1, $arg2) {
        // Inspect function arguments
        echo "Argument 1: " . var_export($arg1, true) . "\n";
        echo "Argument 2: " . var_export($arg2, true) . "\n";
    }

    // Call the function with some test arguments
    myFunction("Hello", [1, 2, 3]);
    ?>
