looks alright to me!

You should make these changes:

register_globals = Off
magic_quotes_gpc = Off

On production sites:

error_reporting = E_NONE ;
display_errors = Off

On development or test sites:

error_reporting = E_ALL ;
display_errors = On

You should also consider the following:

upload_max_filesize = 6M; // user specified max file upload size
session.use_trans_sid = 0; // user specified don't append session ids
register_globals = Off; // register globals on or off
post_max_size = 10M; // user specified post max size
memory_limit = 16M; // user specified Max amt of memory a script may consume (16MB)

according to the header the host put in to the php.ini file it says:

Quote:

;;;;;;;;;;;;;;;;;;;;;;;;;;;
; Bluehost Considerations ;
;;;;;;;;;;;;;;;;;;;;;;;;;;;
; If you would like to change the PHP environment for any PHP files
; in your account, make the changes to this file. Then copy this file to
; all directories, including subdirectories, that have PHP files in them.
;
; NOTE: If you do not copy this file to all directories and subdirectories
; with PHP files, your changes here will not affect those files in other
; directories.

ok so this means i have to put this php.ini file in EVERY joomla directory?
that seems like a lot of work.

I thought you only needed to put it in the root directory but I guess not! Have fun with that...

Insert this file into your root directory (Call it whateveryouwant.php) and call it from your browser. It will distribute your php.ini file to every directory and subdirectory.

Code:

[<?php 
// set this value to Y if you only want to overwrite old php.ini files 
// set this value to N if you want to put a php.ini file in every directory 
$overwriteOnly = "N"; 

if ($overwriteOnly == "Y") echo "Operating in Overwrite Only Mode<br><br>"; 
$path = "/home/" . get_current_user() . "/public_html"; 
$source = $path . "/php.ini"; 
if (!file_exists($source)) die('Error - no source php.ini file'); 
function search($dir) { 
  global $source; 
  global $overwriteOnly; 
  $dh = opendir($dir); 
  while (($filename = readdir($dh)) !== false) { 
    if ( $filename !== '.' AND $filename !== '..' AND $filename !== 'cgi-bin' AND is_dir("$dir/$filename") ) { 
      $path = $dir."/".$filename;  
      $target = $path . "/php.ini"; 
      if (!file_exists($target) AND $overwriteOnly == "Y") { 
        echo "$path <b>skipped - no php.ini file</b><br>"; 
      } else { 
        echo "$target <br>"; 
        if (!copy($source,$target)) echo "<b>Write failed for $target </b><br>"; 
        if (file_exists($target)) chmod($target,0600); 
    } 
      search($path); 
    } 
  } 
  closedir($dh); 
} 
search($path); 
echo "<br>Done."; 
?>

From what I understand about PHP5 (and it depends upon your hosts), the php.ini file does NOT need to be propagated to all directories and subdirectories. Ask the question before running the propagation file (I do have another that will remove all php.ini files, if necessary)

Note: I usually make my changes at the end of the existing php.ini file labelled clearlyy as // USER MODIFIED PARAMETERS FOLLOW

That way you can leave the original php.ini data in place and only modify at one location at the end of the file.

can you share that removal script with me please since i may need to remove all those php.ini files when i figure out where to put that main file?

Here you go. Let us know what you find out about PHP5 and php.ini on your server.

(Edited to add explanation on use)

Insert this file into your root directory (Call it whateveryouwant.php) and call it from your browser. It will delete your php.ini file in every directory and subdirectory.

Code:

<?php 
// this script will delete all your php.ini files 
$path = "/home/" . get_current_user() . "/public_html"; 
function search($dir) { 
  $dh = opendir($dir); 
  while (($filename = readdir($dh)) !== false) { 
    if ( $filename !== '.' AND $filename !== '..' AND $filename !== 'cgi-bin' AND is_dir("$dir/$filename") ) { 
      $path = $dir."/".$filename;  
      $target = $path . "/php.ini"; 
      if (file_exists($target)) { 
        echo "Deleting - $target <br>"; 
        if (!unlink($target)) echo "<b>Delete failed for $target </b><br>"; 
    } 
      search($path); 
    } 
  } 
  closedir($dh); 
} 
$target = $path . "/php.ini"; 
if (file_exists($target)) { 
  echo "Deleting - $target <br>"; 
  if (!unlink($target)) echo "<b>Delete failed for $target </b><br>"; 
} 
search($path); 
echo "<br>Done."; 
?>

It should be noted that both of these scripts will only work on cPanel hosts that haven't changed the user directory path. But it is a very nice script

Damn son that is a very nice script. Something to put away for a rainy day!

I put this php.ini file in my root directory and made the extra .php file telling it to load the ini file in all directories. I'm also running PHP5. I am however still getting the error "Upload Failed". Please help!

Did you check first with your host to see if they allow you to set-up your own php.ini? And, if they do, someone elses would not be appropriate, you need to get your host to provide their starting point.

Hi again, Dave!

Thanks for sending me that email for clarification on how to post the php.ini. Sorry it has taken me a couple of days to respond... I just started medical school this week and it has been hectic!

I created a whatever.php file in notepad by copying and pasting your input script listed above. I placed it in the root directory along with my altered php.ini file. Then, I opened IE and went to http://www.mydomain/whatever.php.  I could see the script but when I checked it out on FileZilla, I didn't find the php.ini file in any other directory than the root. It should be visible, correct? I am running PHP version 4.3.11

Thanks Again!

It should be visible but keep in mind that the script really only works in a cpanel environment where the hosts haven't changed the userr directory paths.

Dave,

Where do I check to see if the host has changed the user directory path? Also, I have a control panel through GoDaddy but do I need to use it to upload the file? Why does the control panel play into the picture, do you know? I just used FileZilla to upload the php.ini and the whatever.php and, as mentioned, pointed my browser to it. However, I am still unable to see the files in any other directory than the root.

Thanks Again,

AZPOD

It is not a control panel but rather cpanel - a very specific control panel provided by many hosting companies. I don't know what go daddy provides for a control panel.

I don't think my control panel is cpanel. When I open the hosting manager software, the option to use the "control panel" is offered and nowhere does is say cpanel that I was able to find.

Is there a way to add the php.ini in all directories and subdirectories other than by hand and the cpanel?

Thanks,

AZPOD

Sorry, I don't have any additonal info on your configuration that would help.

What I read about this:

Quote:

http://www.washington.edu/computing/web ... p-ini.html

Creating Your Own php.ini File

A php.ini file that you write must overwrite every setting in the UW's global php.ini file to achieve full functionality (see note below). Thus you must obtain a copy of the entire recommended php.ini template, rename it to php.ini, and then adjust the settings of the file to the values you desire. When you're done, you can put the file in your root Web directory to apply custom configuration settings to all your PHP scripts, or you can put it in a subdirectory to apply custom configuration settings to a subset of PHP scripts.

Note: you cannot use your configuration file to extend the Web server's PHP settings. Only settings in your own php.ini will be used if you have one. If you set only a few settings, all other settings will use the hard-coded values in the PHP interpreter.

How a php.ini File is Read

When the PHP interpreter starts up, it behaves according to settings specified in any availabe php.ini file. The Web server will look for this file in the following locations and in the following order:

1. The directory from which the PHP script was called
2. The root of your Web directory (typically public_html)
3. The Web server's default php.ini

The Web server's PHP configuration file will always be used if you don't have your own. You can find the Web server's current php.ini file in /usr/local/php4/lib/php.ini on the Web Development systems. Inspecting the settings in this file may be helpful if you are troubleshooting a problem with your configuration

Does this seem OK?
