Delete files off server

[Square1]

Hi all:

Found the following script to delete files created or modified 10+ day old. Problem is it isn't doing the job and I cannot see why. No error messages either. I am on a Windows server using Windows and think that may be it...Any help appreciated.

	if ($handle = opendir('C:\web\mysite\deq\\')) {

	while (false !== ($file = readdir($handle))) { 
    $filelastmodified = filemtime($file);

    if((time()-$filelastmodified) > 10*24*3600)

    {
       unlink($file);
    }

}

closedir($handle); 
}

Have you tried adding an echo statement inside the if() to see if any files even meet the criteria?

Do you have display_errors set to On and error_reporting set to E_ALL?

I tried simplifying things by just doing

		clearstatcache();
		$filename = "C:\web\mysite\deq\6262011.asp";
		if(!file_exists($filename))
  		{
  		die("File not found");
  		}

I just get FILE NOT FOUND

I tried:
$filename = "deq\6262011.asp";
$filename = "\deq\6262011.asp";
$filename = "C:/web/mysite/deq/6262011.asp";

Once again, Windows IIS

For one, I would recommend always using forward slashes for paths to avoid the accidental use of the backslash as an escape character.

Also, are you positive that absolute path is correct? It has to be either a path issue or a permissions issue.

To go with what brad said, in double quotes backslash isn't just an escape mechanism, it also acts as special characters. Think about \n or \r for example.

... which is called an "escape sequence". 😉

(I said "escape character" in an attempt to cover both escaping quotes/etc. as well as those sequences you're referring to.)

[Derokorian]

Guess I didn't know they were called that... I think of escape as like \' to prevent the closing of a string, instead have a quote in the middle of it.

OK guys. After much trial and error the following works. But I haven't seen any examples for this that needed the full path...

if ($handle = opendir('C:/web/mysite/tst/')) {

	while (false !== ($file = readdir($handle))) { 
		$filelastmodified = filemtime('C:/web/mysite/tst/'. $file);

		if((time()-$filelastmodified) > 25*24*3600)
    		{
     		unlink('C:/web/mysite/tst/'.$file);
			}
	}
	closedir($handle); 
	}

It might be possible to simplify it a lot by using [man]glob/man rather than the open/read/close-dir() series of functions.

Something like:

while (glob("C:/web/mysite/tst/*.php") as $file) {
 $filelastmodified = filemtime($file); 
 if((time()-$filelastmodified) > 25*24*3600)
                {
                 unlink('C:/web/mysite/tst/'.$file);
                } 
}
