PHP Configuration


In some cases, a PHP script will require a specific configuration in order to function properly. Many such settings can be changed in your website's PHP Configuration settings. Each of your websites has its own PHP configuration.

For specific settings for specific scripts, you should refer to the requirements or the installation instructions of your script. We have tested several of the more popular scripts and collected our recommendations in the specific articles on this wiki - search for your package to see if we've written anything about it..

IMPORTANT - Changing the PHP configuration options may make result in decreased security for your website and its users. Furthermore, certain scripts may cease to function depending on their PHP configuration requirements.

Resetting Your PHP Configuration

If you've changed your PHP configuration in ways that your PHP scripts do not support, you may find that your site is behaving in unexpected ways. To reset to the default settings:

  1. Log into your Bravenet account
  2. Click on the Web Hosting tab
  3. Look under the Manage Websites heading
  4. Select the website you wish to change the settings for from the list
  5. Now, click on the PHP Configuration link
  6. Click on the reset your PHP configuration link on the right of the pop-up.
  7. When done, click on the Save Configuration link. Note that it takes up to 15 minutes for the options to reset to default.

Note that resetting your settings this way does not change any setting you define using .htaccess files or ini_set() PHP commands.

PHP Configuration Settings

Display Errors (default - on) - This setting controls whether PHP errors should be shown. Having this setting turned on is very useful when installing and setting up PHP programs, or when doing PHP development. However, leaving it on in the long run may be a bad idea - certain error messages can give away some information about the workings of your site that you don't want random people knowing.

Allow URL Fopen (default - off) - This allows your PHP scripts to open files that are hosted elsewhere. By default, PHP will only let you access files located on the same server as your main script.

Permananently Disabled Settings

For security reasons, we have disabled several features of PHP.

exec(), passthru(), proc_open(), shell_exec(), and system() - All these functions, and related functions that run or manipulate programs directly on the server, are disabled. They will not, and can not, be enabled for individual users. Scripts that rely on these functions will not run on our servers.

enable_dl - enable_dl is turned off, and thus prevents the use of dl(). This is partially a security issue, and partially due to the way we run PHP. It's not used by most web scripts, as many web servers do not support this.

Advanced Settings

If you don't see the setting that you are looking for on this screen, you will most likely have to enable it through an .htaccess file or through the ini_set() PHP command.
