etcd is a distributed configuration system, part of the coreos project.
This repository provides a client library for etcd for PHP applications. Inspired by linkorb/etcd-php. For our purpose, we need a more elastic version for etcd client. It can use with predefined HTTP client (no matter what it is) and also supports PHP 7.1.
The etcd-php uses curl library as a default client and creates own instance of http client.
To install etcd, follow instructions that etcd team posts on Releases page of the project:
https://github.com/DatingVIP/etcd/releases/
Easiest way is to install it using composer:
{
"require" : {
"DatingVIP/etcd": "^1.0"
}
}use use DatingVIP\Component\Etcd\Client; $client = new Client('http://127.0.0.1:4001'); // If you have own http client object & if it has proper adapter // proper means - need to implement DatingVIP\Component\Etcd\Client\HttpInterface) $httpAdapter = new MyAdapter($myHttpClient); $client->setHttpClient($httpAdapter); // Get, set, update, remove key if (!$client->keyExists('/key/name')) { $client->keySet('/key/name', 'value'); } $client->set('/key/name', 'value', 10); // Set TTL print $client->keyGet('/key/name'); $client->keyUpdate('/key/name', 'new value'); $client->keyRemove('/key/name'); // Working with dirs if (!$client->dirExists('/dir/path')) { $client->dirCreate('/dir/path'); } $client->dirUpdate('/dir/path', 10); // Set TTL $client->dirRemove('/dir/path'); // Get dir info $client->dirInfo('/dir/path'); // List subdirectories $client->dirList('/dir/path');
Client can be configured not to verify SSL peer:
$client = (new Client('https://127.0.0.1:4001'))->verifySslPeer(false);
as well as to use a custom CA file:
$client = (new Client('https://127.0.0.1:4001'))->verifySslPeer(true, '/path/to/ca/file');
