In what situations would it be more appropriate to use the "a+" mode instead of the "w+" mode when working with files in PHP?

When working with files in PHP, it would be more appropriate to use the "a+" mode instead of the "w+" mode when you want to append data to an existing file without overwriting its content. This is useful when you want to add new data to the end of a file without deleting its current contents.

$file = fopen("example.txt", "a+");

// Append data to the file
fwrite($file, "New data to append");

fclose($file);
