Delete File Copy File

Write text to a file $output_text = "Hello"; file_put_contents("files/output_filename.txt", $output_text); //(Will overwrite an existing file) Note that the directory you write the file to will need chomd set to 777 (php needs the X bit set to be able to write).  This can be a potential security risk if this is a concern.
