Need a script that will delete files??

Hey I have a folder on my site that will collect user created files.

These files are a once use only file. What I was wondering is is there a script I can run with cron to once a day run through that folder only and delete any file of a certain extension (say .jpg)

so like it would be run at 5 p.m. server time and delete any and all *.jpg files in this one folder?

Does that make sense?

nevermind. I got it. I was using unset() instead of unlink().

For those after me, I am using this code and it has tested perfect with one file, and 40 files:

PHP Code:

---

<?php

foreach (glob("*.jpg") as $filename) {
   echo "$filename size " . filesize($filename) . "\n";
   unlink($filename);
}

?>

---

Why use PHP for this task?

Code:

---

rm /home/blizzard/images/temporary/*.jpg

---

Because I will be using cron so I don't have to go back to this folder ever again.

It is just a catch all folder for the created files. Once they are made, they are viewed, and then no longer needed.

So I make the php script, kick it off with cron, and poof, hassle free. :)

But equally you could just execute the above command with cron and remove the need for the PHP script :p

Yes, but then I wouldn't be learning PHP :p

I think the hardest part of learning any language is knowing when it's not the right tool for the job. :)

That's called "beating the crap out of the man", but could actually agree more...:rolleyes:

Also you could just output the generated images directly from the PHP script that called them, and end the whole mess in the first place.

That is true too, but that would defeat the entire purpose of the whole thing. I did think of that though.

I also found that command line code as well, but I still don't like those.

If I have to drive a nail into a 2X4 I can use a hammer, or a mallet. Both will get the job done, one easier than the other, but in the end, if the nail is driven it doesn't matter the way I got it in. :D

If the nail goes in on an angle though, the board will split :)

Yes, but you really appear to be using a steak knife :)
It's interesting mburt decided to bump this thread today, because earlier I found the perfect answer to it in amongst ESR's lesser-known web oddities. :)

Hmm.. I'm not sure how you can use a steak knife in place of a hammer... :)

You can if you bash it with the handle hard enough.
I've tried. :)

(surfer-dude accent) Sweet!!

Oldie but goldie :)

What is that, C++?

Ah, I see.

Lol, no way should a master programmer still be including <windows.h>. :p

:D and all of this because I wanted to do something in php... :rolleyes:

As for that COM object...gagh!

I did enjoy the "Chief Executive", though. :D

Yup. It's all your fault. :)

Maybe stdlib hadn't been standardised yet. :p

I really must learn to use COM at some point. I hate the thought of it, but I know I'm going to need it somewhere on down the line.
