How can beginners effectively troubleshoot parameter passing issues in PHP scripts?

To troubleshoot parameter passing issues in PHP scripts, beginners can start by checking the spelling and case sensitivity of the parameter names in both the function definition and the function call. They should also ensure that the correct number of parameters are being passed to the function. Additionally, beginners can use var_dump() or print_r() to inspect the values of the parameters being passed to the function. 

// Example PHP code snippet to troubleshoot parameter passing issues

function greet($name) {
    echo "Hello, $name!";
}

// Correct way to call the function with the correct parameter
greet("John");

// Incorrect way to call the function with a misspelled parameter
greet("Jane"); // This will not work as the parameter name is misspelled as "namee"
