How can PHP developers troubleshoot and resolve issues related to file writing errors in their code?

File writing errors in PHP can be resolved by checking the file permissions, ensuring the file path is correct, and handling any potential errors that may occur during the writing process. Developers can use functions like `file_put_contents()` or `fopen()` to write to files and check for any error messages returned by these functions to troubleshoot the issue. 

$file = 'example.txt';
$data = 'Hello, World!';

if (file_put_contents($file, $data) !== false) {
    echo 'Data written successfully to file.';
} else {
    echo 'Error writing data to file.';
}
