What are some best practices for handling file writing operations in PHP to avoid issues like the one experienced with fwrite function?

Issue: The fwrite function in PHP can cause issues like data being overwritten or not written properly if not handled correctly. To avoid such problems, it's important to properly handle file writing operations by checking if the file can be opened for writing, writing data to the file, and closing the file after writing. 

// Open file for writing
$file = fopen("example.txt", "w");

if ($file) {
    // Write data to file
    fwrite($file, "Hello, World!");

    // Close file after writing
    fclose($file);
} else {
    echo "Error opening file for writing.";
}
