How can developers effectively troubleshoot and identify errors in their PHP code that affect JS functions?

To effectively troubleshoot and identify errors in PHP code that affect JS functions, developers can use tools like browser developer tools to inspect console errors, check for syntax errors in PHP code that may impact JS functionality, and use error handling techniques like try-catch blocks to catch and log any PHP errors that could be affecting JS functions.

try {
    // PHP code that may affect JS functions
} catch (Exception $e) {
    error_log($e->getMessage());
}
