How can you pass parameters to a PHP function

In PHP, you can pass parameters to a function in several ways. The most common method is to pass them by value, but you can also pass by reference or use default parameters. Here are some examples:


        <?php
        // Function to demonstrate passing parameters by value
        function greet($name) {
            return "Hello, " . $name . "!";
        }

        echo greet("Alice"); // Outputs: Hello, Alice!
        ?>


        <?php
        // Function with default parameters
        function multiply($a, $b = 2) {
            return $a * $b;
        }

        echo multiply(5); // Outputs: 10
        echo multiply(5, 3); // Outputs: 15
        ?>


        <?php
        // Function to demonstrate passing parameters by reference
        function addFive(&$value) {
            $value += 5;
        }

        $number = 10;
        addFive($number);
        echo $number; // Outputs: 15
        ?>
