Using php, how to insert text without overwriting to the beginning of a text file

Question

I have:

 \"\")
{
   fwrite($file,         


        

Answer 1

If you want to put your text at the beginning of the file, you'd have to read the file contents first like:

 "")
{    
    $existingText = file_get_contents($file);
    fwrite($file, $existingText . $_POST["lastname"]."\n");
}

fclose($file);
