How can error reporting and debugging tools help in identifying issues with PHP functions?

Error reporting and debugging tools can help in identifying issues with PHP functions by providing detailed error messages, stack traces, and variable values at runtime. These tools can help pinpoint where the issue is occurring in the code, making it easier to debug and fix the problem. By using these tools, developers can quickly identify and resolve any issues with PHP functions, improving the overall quality and performance of their code. 

// Enable error reporting to display detailed error messages
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Use debugging tools like xdebug or PHP's built-in functions like var_dump() to inspect variable values and debug the code
$x = 5;
$y = 10;
$sum = $x + $y;

var_dump($sum); // Output: int(15)
