It also provides a command line utility: `flushdns`. Compatible with MacOS, Linux, and Windows. 🚀 Installation -------------- [](#-installation) ``` composer require knotsphp/flushdns ``` 📚 Usage ------- [](#-usage) ``` use KnotsPHP\FlushDNS\FlushDNS; // Flush DNS cache $success = FlushDNS::run(); // Only get the command $command = FlushDNS::getCommand(); // Check if the command needs elevated privileges $needsElevation = FlushDNS::needsElevation(); ``` This library also comes some helpers fnuctions for Curl: ``` // Get options to ignore dns cache $flushDnsOptions = FlushDNS::getCurlOpts(); // Make the request $curl = curl_init(); curl_setopt_array($curl, array_merge( [ CURLOPT_URL => "https://app.unolia.com/api/v1/domains", CURLOPT_RETURNTRANSFER => true, CURLOPT_HTTPHEADER => [ "Accept: application/json", "Authorization: Bearer 123" ], ], $flushDnsOptions, )); $response = curl_exec($curl); $domains = json_decode($response); curl_close($curl); ``` 📚 Use in command line --------------------- [](#-use-in-command-line) You can also use this library in the command line by using the `flushdns` command. It's recommended to install the library globally to use it in the command line. ``` composer global require knotsphp/flushdns ``` Then you can use the `flushdns` command to get the public IP address of the current machine. ``` # In your project directory vendor/bin/flushdns # Globally installed flushdns ``` 📖 Documentation --------------- [](#-documentation) This library is compatible with MacOS, Linux, and Windows. Some operating systems may require root access to flush the DNS cache. 📋 TODO ------ [](#-todo) - Add argument to public static method to get a command for a specific OS. (needs knotsphp/system updated) - Add support for more operating systems. - Add support for running elevated commands on MacOS and Linux by passing the password as an argument or having a gui prompt depending of the context. (needs knotsphp/elevated to be written) 🤝 Contributing -------------- [](#-contributing) Clone the project and run `composer update` to install the dependencies.
