Creating a custom php.ini file

[Chaos25]

You may want to use a custom php.ini file in order to change some of the host defaults. For example, you should ensure register_globals = off for improved script security. If you copy the default host file, make changes, and then put it in your webspace, you may not know if your host makes further changes to the default file which could cause your file to be out-of-date. A good solution is the following script, which you can execute manually or kick-off with cron each night. The script reads the host default file, makes your changes, and writes it to your directory. Now you can always have the current host default php.ini file with your changes made.

Note - you may have to change the file/directory paths in the examples below to match your hosting environment.


<?php
// Put all the php.ini parameters you want to change below. One per line.
// Follow the example format $parm[] = "parameter = value";
$parm[] = "register_globals = Off";
$parm[] = "session.use_trans_sid = 0";
// full unix path - location of the default php.ini file at your host
// you can determine the location of the default file using phpinfo()
$defaultPath = '/usr/local/lib/php.ini';
// full unix path - location where you want your custom php.ini file
$customPath = "/home/user/public_html/php.ini";
// nothing should change below this line.
if (file_exists($defaultPath)) {
$contents = file_get_contents($defaultPath);
$contents .= "\n\n; USER MODIFIED PARAMETERS FOLLOW\n\n";
foreach ($parm as $value) $contents .= $value . " \n";
if (file_put_contents($customPath,$contents)) {
if (chmod($customPath,0600)) $message = "The php.ini file has been modified and copied";
else $message = "Processing error - php.ini chmod failed";
} else {
$message = "Processing error - php.ini write failed";
}
} else {
$message = "Processing error - php.ini file not found";
}
echo $message;
?>


You may want to change other things in php.ini as well. You can do this by repeating the $parm[] statement for as many changes as you wish to make.

For example you may want to use your own temp directory for session files. To do this add the following line:
$parm[] = "session.save_path = /home/user/temp"; // user specified temp session file directory
Note the sessions directory is above the public directory for added security.

You may want to use your own temp upload directory for improved security. To do this add the following line:
$parm[] = "upload_tmp_dir = /home/user/temp"; // user specified temp upload directory
Note the uploads directory is above the public directory for added security.

If you want to change the maximum file upload size to something larger than 2MB, add the following:
$parm[] = "upload_max_filesize = 4M"; // user specified max file upload size

And if you want to go larger than 8MB, also add the folowing:
$parm[] = "post_max_size = 10M"; // user specified post max size

save it as php.ini and put it in the public_html

It's basically the same as using .htaccess to override the php.ini file, but instead you can use normal PHP file if .htaccess is banned. It all comes down to the settings in the php.ini file, as said it doesn't always work.
