How can PHP developers effectively debug and test code to ensure proper functionality when working with language files for text display?

When working with language files for text display in PHP, developers can effectively debug and test code by using functions like `var_dump()` or `print_r()` to inspect variables and ensure they contain the correct values. Additionally, developers can use tools like Xdebug for more advanced debugging capabilities. It's also important to test the code with different language files to ensure proper functionality across different translations. 

// Example code snippet for debugging and testing language files in PHP
$languageFile = 'english.php';
$translations = include $languageFile;

// Debugging to check the contents of the language file
var_dump($translations);

// Testing the translation functionality
echo $translations['hello']; // Output: Hello
