Are there any best practices for troubleshooting PHP installation issues related to internet connectivity?

When troubleshooting PHP installation issues related to internet connectivity, a common solution is to check if the PHP configuration file (php.ini) has the correct settings for internet connectivity. Ensure that the "allow_url_fopen" and "allow_url_include" directives are set to "On" to allow PHP to access remote files and URLs. Additionally, check if there are any firewall or network restrictions preventing PHP from connecting to the internet.

// Check if 'allow_url_fopen' and 'allow_url_include' directives are set to 'On'
if (ini_get('allow_url_fopen') != '1' || ini_get('allow_url_include') != '1') {
    // Set the directives to 'On'
    ini_set('allow_url_fopen', '1');
    ini_set('allow_url_include', '1');
}
