Hello:
I have a directory on a server that has php code that creates and
writes to directories as such; /tiles_.*/.
Each directory with a matching name has graphics files written to it.
i'm trying to write a script the will
eliminate the graphics files and the directories they are in
(tiles_.*). The present code is:
<?php
function prune()
{
$f = 0;
$pat = 'tiles_.*';
$view = array();
$t = array();
$str = '';
$start = opendir('.');
//print"Hello???<br>"; debug code
while($lst = readdir($start))
{
if(ereg($pat, $lst))
{
$t[$f] = $lst;
$str .= $t[$f].'<br>'; //debug code
}
$f++;
}
rewind($start);
closedir($start);
//print $str; debug code----the array $t has all valid
values at this point.
for($f = 0; $f < count($t); $f++)
{$tmp = $t[$f];
chdir($tmp);
$dir = opendir($tmp);
$r = 0;
while($i = readdir($dir))
{
@unlink($i);
$r++;
};
rewind($dir);
closedir($dir);
unset($dir);
chdir('../');
rmdir($tmp);
}
}
prune();
?>
The problem is that each time the for loop tries to chdir to an array
$t item, errors regarding invalid resources and none existent files are
generated.
If I use chdir('./'.$tmp) and opendir('./'.$tmp) the code removes all
the files in the directory the script is located in, including the
script file itself.
So, I am thinking that, in this case, the directories aren't even
changed when the @unlink() line is reached and unlink() only sees the
current
directory files and not included directories, and removes everything
that isn't a directory.
Here is a sample of the errors generated:
Warning: chdir() [function.chdir]: No such file or directory (errno 2)
in (path)/prune.php on line 30 // (all resources used based on this are
invalid)
and;
Warning: opendir(tiles_9215fd05) [function.opendir]: failed to open
dir: No such file or directory in
/var/www/html/exp/tile_puzzle/prune.php on line 31
(this happens on the second iteration of the loop......tiles_9215fd05
is a valid array $t item)
So, Can someone tell me what I might be doing wrong here. I don't want
to swim around with any more trial and error if possible.
I'm using php 5.1.2, Apache 1.3.34
Thanks in advance.
JK
