Adding new data at beginning.

Hi! I am trying to put in a new data at the beginning of a file. I have started like this; -------- $yourfile = "test.xml"; (<a><b><c><d><e><f></c> this is the file.) $fp = fopen ($yourfile, r); $message = array(1 => '<a>', '<b>', '<c>', '<d>', '<e>', '<f>', '</c>'); Here I need some code to get the output look like this"<a><b><new><c><d><e><f></c>" print_r($message); fwrite ($fp, $message); fclose ($fp); I am thankful for any help. Regards Jan
