How can debugging tools like log files or profilers help identify issues related to function calls and code execution in PHP?

Debugging tools like log files or profilers can help identify issues related to function calls and code execution in PHP by providing insights into the flow of the program and the values of variables at different points in the code. Log files can help track the execution path and identify any errors or unexpected behavior, while profilers can analyze the performance of different functions and pinpoint any bottlenecks in the code. 

// Example of using log files to track function calls in PHP
function myFunction($param) {
    error_log('Calling myFunction with parameter: ' . $param);
    
    // Function logic goes here
}

myFunction('example_param');
