What are some recommended methods for replacing non-ASCII characters in PHP to ensure compatibility with different servers?

When dealing with non-ASCII characters in PHP, it's important to ensure compatibility across different servers by replacing them with ASCII equivalents. One recommended method is to use the `iconv()` function in PHP, which allows you to convert strings between different character encodings. By using `iconv()` with the `TRANSLIT` option, you can replace non-ASCII characters with their closest ASCII equivalents. This helps ensure consistent behavior regardless of the server's configuration. 

// Input string with non-ASCII characters
$inputString = "Café au Lait";

// Replace non-ASCII characters with ASCII equivalents using iconv()
$cleanString = iconv('UTF-8', 'ASCII//TRANSLIT', $inputString);

// Output the cleaned string
echo $cleanString;
