What are some recommended approaches for debugging PHP code, especially for beginners facing issues with function execution?

When facing issues with function execution in PHP, beginners can use the following approaches for debugging: 1. Check for syntax errors or typos in the function definition. 2. Use print_r() or var_dump() to inspect variables and values within the function. 3. Step through the code using a debugger tool to identify the point of failure. 

// Example code snippet demonstrating debugging techniques for function execution issues

function myFunction($param) {
    // Check for syntax errors or typos in the function definition
    if ($param === 'example') {
        // Use print_r() or var_dump() to inspect variables and values
        var_dump($param);
    } else {
        echo 'Parameter is not "example"';
    }
}

// Call the function with a parameter to test
myFunction('example');
