fopen errors

[metazai]

Ok, I've built a CMS and installed same on several different servers. Occasionally I've had problems with the PHP code that writes to the created pages and files, but nearly always they've been permissions problems and once the fopen setting in php.ini. Now, however, I'm on a server that's thrown me another curve ball -- no matter what the permissions are on files, folders, or whatever -- even 777! -- I still get:

Warning: fopen(../../index.php) [function.fopen]: failed to open stream: Permission denied in /home/warriorg/public_html/admin/includes/publish.php on line 46
can't open ../../index.php

Incredibly frustrating . . . fopen is turned on in the .ini, and I'm at a loss of what to check next. Anybody with any thoughts? Remember this same code has worked literally on 10 other servers.

fopen( realpath( dirname(__FILE__).'/../../index.php' ) )

Ok, so I've been using

$fh = fopen($myFile, 'w') or die("can't open ".$myFile);

. . . probably should have posted that to begin with. Not sure how this fits in with your code. I've tried a few iterations, but I'm a bit confused (which I often am, so it's a comfortable place).

failed to open stream: Permission denied

does the web user have permission to read this file?

[metazai]

How do you mean? It won't work even when all permissions are set to 777 -- which user are you referring to?

[sde]

i'm talking about the apache user. if permissions are 777, and you still can't open it, then it must be something else.

have you tried it with another file? did it work before, then break?

[DJMaze]

Did someone really try my answer?

If not you won't see the exact error.

[metazai]

I couldn't interpret how your answer worked in place of the code I'd been putting, DJMaze . . . should I just replace _____FILE_____ AND index.php with my $myfile variable?

[sde]

i think __FILE__ is a constant for the current file. 2 underscores on each side.


edit: yeah here it is 'magic constant'

Cool . . . never heard of that one.

Regardless, now I don't get an error on fopen anymore with this (sorry DJMaze, I had to add in the 'w' or I got another error warning me it was missing):

$fh=fopen( realpath( dirname(__FILE__).$myFile),'w' );

But now, when I go to write the results to the file later after defining $bodysection and using

fwrite($fh, $headsection);

The result is that I get:

Warning: fwrite(): supplied argument is not a valid stream resource in /home/warriorg/public_html/admin/includes/publish.php on line 73

Can you check the output of

echo realpath( dirname(__FILE__).$myFile)

It seems that something is wrong with open_basedir or safemode.

[metazai]

It's completely blank. No value. Null.
