What are common errors that can occur when using unlink() in PHP, such as the "No such file or directory" warning?

When using unlink() in PHP to delete a file, a common error that can occur is the "No such file or directory" warning. This error typically happens when the file being targeted for deletion does not exist in the specified directory. To avoid this warning, you can first check if the file exists before attempting to delete it using unlink(). This can be done using the file_exists() function in PHP. 

$file_path = 'path/to/file.txt';

if (file_exists($file_path)) {
    unlink($file_path);
    echo 'File deleted successfully.';
} else {
    echo 'File does not exist.';
}
