How can PHP developers handle encoding issues when writing to text files, especially when dealing with special characters or symbols?

When writing to text files in PHP, developers can handle encoding issues by ensuring that the file is opened with the correct encoding, such as UTF-8. This can help prevent special characters or symbols from being improperly displayed or saved. Additionally, developers can use functions like utf8_encode() or utf8_decode() to convert strings to UTF-8 encoding before writing them to the file. 

$file = fopen('example.txt', 'w');
fwrite($file, utf8_encode($textToWrite));
fclose($file);
