Deleting contents of all folders - php

Question

I have a table with the names of all the folders I wish to delete the contents off. Now I have a script which will delete the entire contents of a folder that I set. Now I though I could put that code in a while loop and it would delete the contents of all the folders. However, I get an error. Here is the code, error is at the bottom, what's going wrong and how do I fix this?
$query = "SELECT * FROM gemeentes";
$result = mysql_query($query) or die(mysql_error());
while($row = mysql_fetch_array($result)){
$gemeente1 = str_replace(" ","",$row['gemeente']);
$gemeente2 = strtolower($gemeente1);
$gemeente3 = str_replace("(","-",$gemeente2);
$gemeente4 = str_replace(")","",$gemeente3);
$gemeente5 = str_replace(",","",$gemeente4);
if(isset($_POST['GO'])) {
$directory = "../subdomains/".$gemeente5."/httpdocs/";
echo $directory;
define('PATH', $directory);
function destroy($dir) {
$mydir = opendir($dir);
while(false !== ($file = readdir($mydir))) {
if($file != "." && $file != "..") {
chmod($dir.$file, 0777);
if(is_dir($dir.$file)) {
chdir('.');
destroy($dir.$file.'/');
rmdir($dir.$file) or DIE("couldn't delete $dir$file<br />");
}
else
unlink($dir.$file) or DIE("couldn't delete $dir$file<br />");
}
}
closedir($mydir);
}
destroy(PATH);
echo 'all done.';
}
}
The first delete comes back fine, the second won't do the trick anymore:
../subdomains/aaenhunze/httpdocs/all done.../subdomains/aalburg/httpdocs/
Fatal error: Cannot redeclare destroy() (previously declared in /vhosts/url.nl/httpdocs/deletecontent.php:50) in /vhosts/url.nl/httpdocs/deletecontent.php on line 50

Answer 1

Why are you calling your function as destroy(PATH); with a "define"d constant instead of just the actual underlying variable as: destroy($directory);? Once you take the function out of the loop as Bulk suggested, this should work I'd think...

Answer 2

You are defining the destroy function inside the outermost while loop, so the second time it comes to run the loop the function is already defined. Move the function definition to outside of the while loop to fix this.

Answer 3

Thank you all for the help. I took a look at all your answers and what OzgurH suggested did the trick. The working code:
$query = "SELECT * FROM gemeentes";
$result = mysql_query($query) or die(mysql_error());
while($row = mysql_fetch_array($result)){
$gemeente1 = str_replace(" ","",$row['gemeente']);
$gemeente2 = strtolower($gemeente1);
$gemeente3 = str_replace("(","-",$gemeente2);
$gemeente4 = str_replace(")","",$gemeente3);
$gemeente5 = str_replace(",","",$gemeente4);
if(isset($_POST['GO'])) {
$directory = "../subdomains/".$gemeente5."/httpdocs/";
echo $directory;
destroy($directory);
echo 'all done.';
}
}
function destroy($dir) {
$mydir = opendir($dir);
while(false !== ($file = readdir($mydir))) {
if($file != "." && $file != "..") {
chmod($dir.$file, 0777);
if(is_dir($dir.$file)) {
chdir('.');
destroy($dir.$file.'/');
rmdir($dir.$file) or DIE("couldn't delete $dir$file<br />");
}
else
unlink($dir.$file) or DIE("couldn't delete $dir$file<br />");
}
}
closedir($mydir);
}
