What is the common approach to deleting files in PHP after processing data from them, and what potential pitfalls should be considered?

When processing files in PHP, it's common to delete them after data has been extracted to free up storage space and maintain data integrity. The most common approach is to use the `unlink()` function in PHP to delete the file once processing is complete. However, it's important to handle potential errors that may arise, such as file permission issues or file not found errors. 

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

// Process data from the file

if (unlink($file_path)) {
    echo "File deleted successfully";
} else {
    echo "Error deleting file";
}
