Browscap (Browser Capability) is a feature in PHP that helps in detecting browser capabilities. Whether you are using a standard PHP installation or running CloudLinux, this guide will walk you through enabling browscap for PHP 8.1.

For Standard PHP Installations

Step 1: SSH into Your Server

1. Open your terminal.
2. SSH into your server:

   ssh root@your-server-ip

Replace your-server-ip with your server’s IP address.

Step 2: Navigate to the PHP 8.1 Configuration Directory

1. Change to the PHP 8.1 configuration directory:

   cd /opt/cpanel/ea-php81/root/etc/php.d

Step 3: Download the Browscap File

1. Download the latest browscap.ini file:

   wget https://browscap.org/stream?q=PHP_BrowsCapINI

2. Rename the downloaded file:

   mv stream\?q\=PHP_BrowsCapINI php_browscap.ini

Step 4: Edit the php.ini File

1. Open the php.ini file:

   vim /opt/cpanel/ea-php81/root/etc/php.ini

2. Add or modify the [browscap] section:

   [browscap]
   browscap = /opt/cpanel/ea-php81/root/etc/php_browscap.ini

3. Save and close the file.

Step 5: Restart Apache

1. Restart Apache:

   service httpd restart

(Use apache2 if applicable.)

Step 6: Verify the Configuration

1. Create a PHP file (e.g., info.php) with:

      <?php
    $browser = get_browser();
    print_r($browser);
    phpinfo();
    ?>

2. Access this file through your web browser and check for the browscap directive.

For CloudLinux Servers

Step 1: Download the Browscap Configuration File

1. Download the browscap.ini file:

   wget https://browscap.org/stream?q=PHP_BrowsCapINI

2. Move the file to the directory for PHP 8.1:

   mv stream\?q\=PHP_BrowsCapINI /opt/alt/php81/etc/php.d.all/browscap.ini

Step 2: Edit the php.ini File

1. Open the PHP 8.1 php.ini file:

   vim /opt/alt/php81/etc/php.ini

2. Locate or add the [browscap] section:

   [browscap]
   browscap = /opt/alt/php81/etc/php.d.all/browscap.ini

3. Save and close the file.

Note: Repeat these steps for each PHP version if browscap needs to be enabled globally.

Step 3: Rebuild CageFS Parameters

1. Rebuild the PHP configuration within CageFS:

   cagefsctl --rebuild-alt-php-ini
   cagefsctl --force-update

Step 4: Test the Configuration

1. Create a PHP file (e.g., test_browscap.php) with:

   <?php
   $browser = get_browser(null, true);
   print_r($browser);
   phpinfo();
   ?>

2. Access this file through your web server to check if browscap is functioning correctly.

Enabling browscap for PHP 8.1 allows for accurate browser detection and improved user experience. Whether you are working with a standard PHP installation or a CloudLinux server, these steps will help you configure browscap effectively. Keep your browscap.ini file updated to ensure accurate browser capability data.

Feel free to adjust these instructions based on your specific server setup and PHP versions.
