问题
I am trying to get a variable from the query string and write it to a text file. I have tried like this:
<?php
$content=( $_GET['var'] );
echo $content;
$file = fopen("etlLOG.txt","w+");
echo fwrite($file,$content);
fclose($file);
?>
I get the following errors:
Warning: fopen(etlLOG.txt) [function.fopen]: failed to open stream: Permission denied in E:\Users\george\listener.php on line 8
Warning: fwrite(): supplied argument is not a valid stream resource in E:\Users\george\listener.php on line 9
Warning: fclose(): supplied argument is not a valid stream resource in E:\Users\george\listener.php on line 10

You may need to change the permissions as an administrator. Open up terminal on your Mac and then open the directory that etlLOG.txt is located in. Then type:
sudo chmod 777 etlLOG.txt
You may be prompted for a password. Also, it could be the directories that don't allow full access.
OR
PHP
chmod : Attempts to change the mode of the specified file to that given in mode.
chmod

Well it appears that the web server does not have access to that file. So used ftp fopen provided the correct credentials and paths and finally i did managed to access and edit the file

If you are running WAMP on windows
1) login as an administrator
2) Install wamp
3) Download subinacl.exe from microsoft:
4) grant permissions to the regular user account to manage the WAMP services: (subinacl.exe is in C:\Program Files (x86)\Windows Resource Kits\Tools)
subinacl /SERVICE \MachineName\wampapache /GRANT=domainname.com\username=F subinacl /SERVICE \MachineName\wampmysql /GRANT=domainname.com\username=F
5) logout and log back in as the user. They should now be able to launch the WAMP taskbar application and control the WAMP service.

My guess is that PHP is trying to create the file at 'C:\WINDOWS', so the solution wouldn't be to set permissions there.
I would suggest you use a specific location, example: create a folder at the same location as your php script and use it to create the files:
$filePath = dirname(_FILE_) . "/temp_vars/etILOG.txt";
$file = fopen($filePath ,"w+");
Kind regards,

The code you are running is trying to create the etlLOG.txt in the same folder as your PHP script. You need to give Full Permission to your IUSER_ account on the E:\Users\george folder.
