Answer 1

Using fopen, fseek, ftell, fwrite, and fclose:

// Create the file handler
$file = fopen("filename", "r+");
// Seek to the end
fseek($file, SEEK_END, 0);
// Get and save that position
$filesize = ftell($file);
// Seek to half the length of the file
fseek($file, SEEK_SET, $filesize / 2);
// Write your data
fwrite($file, "Data");
// Close the file handler
fclose($file);
