How can PHP developers effectively debug and troubleshoot issues related to passing variables between different PHP files?

When troubleshooting issues related to passing variables between different PHP files, developers can utilize PHP's built-in debugging functions like var_dump() or print_r() to inspect the variables and their values at different points in the code. Additionally, using error_reporting(E_ALL) can help catch any potential errors or warnings related to variable passing. Lastly, ensuring that variables are properly scoped (global, local, static, etc.) and using include or require statements correctly can also help in resolving variable passing issues. 

// Debugging variable passing between different PHP files
error_reporting(E_ALL);

// File 1: passing_variable.php
$var = "Hello from file 1!";
include 'receiving_variable.php';

// File 2: receiving_variable.php
var_dump($var);
