I see no reason yet for this permission denied.

[sepoto]

Wow! My file has full 777 access rights set. For some reason PHP is giving me a permission denied when I try to write to the file!

<?php
$yturl = $_POST['txtbx_youtube'];
$fp = fopen('urldata.dat', 'w');
fwrite($fp,$yturl);
fclose($fp);
?>

Warning: fopen(urldata.dat) [function.fopen]: failed to open stream: Permission denied in /var/www/html/writefile.php on line 3

Check that PHP isn't in safe mode.

(As an aside, 777 is rarely an appropriate permissions set for anything.)

[sepoto]

Here is a snapshot from my php.ini file. The only thing I have done to it since I installed is turn on display errors. It looks to me like safe mode is indeed off. Sorry about the 777 permissions but I am new to Linux and still learning every day how to work with it. Is there anything I can do to troubleshoot this problem? Is this a bug? Is there anything at all that can be done?

; Safe Mode
; http://www.php.net/manual/en/ini.sect.safe-mode.php#ini.safe-mode
safe_mode = Off

; By default, Safe Mode does a UID compare check when
; opening files. If you want to relax this to a GID compare,
; then turn on safe_mode_gid.
; http://www.php.net/manual/en/ini.sect.safe-mode.php#ini.safe-mode-gid
safe_mode_gid = Off

; When safe_mode is on, UID/GID checks are bypassed when
; including files from this directory and its subdirectories.
; (directory must also be in include_path or full path must
; be used when including)
; http://www.php.net/manual/en/ini.sect.safe-mode.php#ini.safe-mode-include-dir
safe_mode_include_dir =

; When safe_mode is on, only executables located in the safe_mode_exec_dir
; will be allowed to be executed via the exec family of functions.
; http://www.php.net/manual/en/ini.sect.safe-mode.php#ini.safe-mode-exec-dir
safe_mode_exec_dir =

Your security label is blocking write.

httpd_sys_content_t is for read only data interpreted by apache.

If you want a directory/file to be writable then it must be labeled
httpd_sys_rw_content_t

Thank you kindly. I will update the necessary settings right away. Rack up more points for this forum which is always full of answers.
