How can the issue of overwriting previous entries in gb.txt be resolved when adding new entries in PHP?

The issue of overwriting previous entries in gb.txt when adding new entries in PHP can be resolved by opening the file in append mode ('a') instead of write mode ('w'). This way, new entries will be added to the end of the file without overwriting existing content. 

// Open the file in append mode
$file = fopen('gb.txt', 'a');

// Add the new entry
$newEntry = "New entry to add to gb.txt\n";
fwrite($file, $newEntry);

// Close the file
fclose($file);
