trouble with deleting files and folders

[tariel]

I have some problem with deleting files and folders. I have a script that
deletes the files and folders inside another folder. Here it is:

<?php 
$centre_id = 16; 

if(!($result11 = mysql_query("SELECT ct_centre_id, ct_centre_name from ct_centre WHERE ct_centre_id = '$centre_id'", $con))) 
{ 
      Error(sprintf("Internal Error %d:%s\n",mysql_errno(),mysql_error())); 
            exit(); 
} 

$row11 = mysql_fetch_array($result11); 
$centre_id = $row11["ct_centre_id"]; 
$centre_name = $row11["ct_centre_name"]; 

if(!($result12 = mysql_query("SELECT student_id from ct_centre_coaches WHERE ct_centre_id = '$centre_id'", $con))) 
{ 
                  Error(sprintf("Internal Error %d:%s\n",mysql_errno(),mysql_error())); 
                  exit(); 
} 

$num_results = mysql_num_rows($result12); 
$count = 0; 
$id= 0; 
for ($i=0; $i<$num_results; $i++) 
{ 
     $row12 = mysql_fetch_array($result12); 
     $coach_id = $row12["student_id"]; 

 if(!($result13 = mysql_query("SELECT ct_cdc_deliv_topic_id from ct_cdc_deliv_topic WHERE ct_centre_id = '$centre_id'", $con))) 
 { 
      Error(sprintf("Internal Error %d:%s\n",mysql_errno(),mysql_error())); 
      exit(); 
 } 
 // Delete entries from deliverable tables. 
 while($row13 = mysql_fetch_array($result13)) 
 { 
       $ct_topic_id = $row13["ct_cdc_deliv_topic_id"]; 

       $center_path = "".$cdc_path."/centre".$centre_id.""; 
       $dir2remove =  "".$cdc_path."/centre".$centre_id."/coach".$coach_id."/topic".$ct_topic_id."/version".$version."/"; 

       if ($dir = @opendir("$dir2remove")) 
       { 
           while (($file = readdir($dir)) != false) 
           { 
                 if (!($file=="." || $file=="..")) 
                 { 
                    chdir($center_path."/coach".$coach_id."/topic".$ct_topic_id."/version".$version."/"); 
                    unlink($center_path."/coach".$coach_id."/topic".$ct_topic_id."/version".$version."/".$file.""); 

                    chdir($center_path."/coach".$coach_id."/topic".$ct_topic_id."/"); 
                    unlink($center_path."/coach".$coach_id."/topic".$ct_topic_id."/".$file.""); 

                    chdir($center_path."/coach".$coach_id."/"); 
                    unlink($center_path."/coach".$coach_id."/".$file.""); //   ?? 

                    chdir($center_path."/"); 
                    unlink($center_path."/".$file."");  //    ?? 
                 } 

           } //close while 
           closedir($dir); 

           rmdir($center_path."/coach".$coach_id."/topic".$ct_topic_id."/version".$version."/"); 
           rmdir($center_path."/coach".$coach_id."/topic".$ct_topic_id."/"); 
           rmdir($center_path."/coach".$coach_id."/"); //        ?? 
           rmdir($center_path."/"); //      ?? 
       } 
} 

$stat =  "center has been deleted"; 
} 
?> 
 

So, when i run it , it actually works and deletes the stuff, but at the same time it gives the following kind of errors:
Warning: Unlink failed (No such file or directory) in c:.....\script.php on line 71

Warning: RmDir failed (Permission denied) in c:...\script.php on line 79

for lines I marked in the code with "??" sign.
Can someone tell what is the problem ?

Try letting it output the dir it is trying to delete when it fails?

if (!rmdir(...)) echo ...

Thanx for reply! 😃
I guess i figured out what was the problem. The problem was with while loop. Because actually sometimes it needs to run few times to delete few folders. But it occured so that it ran across empty or none existing folders, because they have been already deleted at first run of loop. And that's why those warnings appeared. Anyways here is a fixed version of code:

[nightowl]

that is indeed what I expected too, which is why I asked you to show the dirs you are trying to delete.

Yep, that helped. 😃
