Once glob() makes it into the production version,
foreach(glob('*') as $f) unlink($f);
Until then, use system('rm *'); or a readdir loop.
unlink() is not the rm command. It's a system call that deletes a specific
named file.

Just be aware that if the name is based on the username, it'll be easy for other people to guess the names of files on your computer and possibly inject code into it.

Re: [PHP] Unlink question more or less
Yeah they are, actaully I switched it to a static name and then added the time stamp as part of the information I'm gathering. Now I just re-write the file on each log in.

RE: [PHP] Unlink question more or less
You can't use wildcards. Use a system() or exec() call to do it. Why use the datetime part at all? The usernames are unique, right? ---John Holmes... > -Original Message- > From: Tom Ray [mailto:[EMAIL PROTECTED]] > Sent: Tuesday, June 11, 2002 11:06 PM > To: [EMAIL PROTECTED] > Subject: [PHP] Unlink question more or less > > I want to use unlink() to delete a wildcard, but at the moment I keep > getting parse errors.

[PHP] Unlink question more or less
I want to use unlink() to delete a wildcard, but at the moment I keep getting parse errors. Here's what happening: I'm mucking around with some login stuff, when a user logs in it writes a flat file that collects some information about them, the flat file is created with the name username.dateyeartime Now each time they log in I want to delete that file and replace it with the new file that has the latest dateyeartime ending on it. I've tried unlink (username.*); but that returns an error. Is there a way for unlink() to recongize wildcards? If not how would I do this? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
