how can i creat a file and write a string to it!

i've been looking for an adequate answer all morning in the archives, but can't find one, neithr can i understand the manual. all i want to do is for php to take the strong sent to it through a form, and create a new file with a name "2.html" for example, and write the string to it. how can i quickly do this please? i got this so far but that gives me some filehandler problem. i'm running off a unix system btw. $lastid = mysql_insert_id() ; $root = "/home/articles/"; $file = $root . $lastid . ".html"; fwrite($file, $articletext); tia!! /sunny ____________________________________________________________ Do You Yahoo!?
