How can fsockopen() be activated on a web server running PHP?

To activate fsockopen() on a web server running PHP, the PHP configuration must have the 'allow_url_fopen' directive set to 'On' in the php.ini file. This directive allows PHP to open URLs as files, enabling functions like fsockopen() to establish network connections. Once the directive is set, the web server must be restarted for the changes to take effect. 

// Check if 'allow_url_fopen' directive is enabled
if (ini_get('allow_url_fopen') == 'Off') {
    // Set 'allow_url_fopen' directive to 'On'
    ini_set('allow_url_fopen', 'On');
    // Restart web server for changes to take effect
    // This step may vary depending on the server configuration
}
