chmod

[alifyag]

hello,
i have a small query. i have the following function where a file is opened and something is written to it.

function appendToLog ($filename, $data) {
//Open file
$file = fopen($filename,"aw");
//Write data
fputs($file,$data);
//Close file
fclose($file);
}

Now the first time soemthing is written to the file it works fine. but when soemthing has to be written again then it says Permission denied. the permission on the file is -rw-r--r-- when created. how do i make it rw-rw-rw- in the function.
Also i never delete this file. it always exists after i create it the first time
thanks

I'm not sure that this is it, since I'm a newbie, but shouldn't it say
"a" instead of "aw"... Like this:

function appendToLog ($filename, $data) { 
//Open file 
$file = fopen($filename,"a"); 
//Write data 
fputs($file,$data); 
//Close file 
fclose($file); 
}

Do a chmod on it. I would not make it writable by everyone. Only give minimum perms necessary. If you run PHP as an Apache mod, and Apache runs as nobody or apache, you only want to give W perms to the user Apache runs as. If Apache is not the file owner and Apache is not part of the group, then do a chmod o+w myfile.txt. In other words, give "other" write perms. Of course there are security issues anytime you allow files to be written on your system.

i tried
function appendToLog ($filename, $data) {
//Open file
$file = fopen($filename,"aw");
//Write data
fputs($file,$data);
//Close file
fclose($file);
chmod ($file, 0666);
}

but couldnt get it to work

This should do it. It will always add to the end of the file and if the file doesn't exist create it.

$file = fopen($filename,"a+");
