Oh this is easy =P
Lets say or file is "file.txt"
$fopen = fopen('file.txt','r+'); // Open the file with read and write permissions. However, this will write overwrite the contents of the file when written. To fix it, change r+ to a+.
$write = "Message to be written";
fwrite($fopen,$message); // Writes the message ($message) to the file. $fopen picks the file.
fclose($fopen); // Closes the file.
?>

I suggest something like this:* Open file1 and file2 * Create a temporary output file, for writing * Read a line from file1, write it into the output file * Read a line from file2, write it into the output file * Repeat the previous two steps, while you are not at end-of-file in either of the two files * At this point, if you are NOT at end-of-file in file1, read the remaining lines of file1, and write them to the output (you can write a loop for this). * Similarly, if you are NOT at end-of-file in file2, read and write the remaining file. * Close file1, file2, and the output file. * Copy the temporary output file back to file1 * Erase the temporary output file
