How can error messages indicating missing arguments in PHP functions be effectively troubleshooted and resolved?

When encountering error messages indicating missing arguments in PHP functions, it is important to carefully review the function calls and ensure that all required arguments are being passed correctly. Double-check the function definition to see how many arguments are expected and make sure they are provided in the correct order. If necessary, update the function call to include the missing arguments.

// Example function with missing arguments
function greet($name, $greeting) {
    echo "$greeting, $name!";
}

// Incorrect function call with missing argument
$name = "Alice";
greet($name); // Missing $greeting argument

// Corrected function call with both arguments provided
$greeting = "Hello";
greet($name, $greeting); // Outputs: Hello, Alice!
