Php CouchDB Connectivity

In this tutorial, we are explaining an example of php CouchDb connectivity. Php provides easy way to connect. We just need to execute a Php script given below.

CouchDB by default executes on the 5984 port.

1) Creating a Php file

// index.php

 <?php $options[‘host’] = “localhost”;  $options[‘port’] = 5984; // Creating connection $couch = new CouchSimple($options);  $couch->send(“GET”, “/”);  // Create a new database “tutoraspire”. $couch->send(“PUT”, “/tutoraspire”);  // Create a new document in the database. $couch->send(“PUT”, “/tutoraspire/24”, ‘{“_id”:”24″,”name”:”John”}’);  // Fetching document $resp = $couch->send(“GET”, “/tutoraspire/24”);  echo $resp;  class CouchSimple { function CouchSimple($options) { foreach($options AS $key => $value) { $this->$key = $value; } }  function send($method, $url, $post_data = NULL) { $s = fsockopen($this->host, $this->port, $errno, $errstr);  if(!$s) { echo “$errno: $errstrn”;  return false; }  $request = “$method $url HTTP/1.0rnHost: $this->hostrn”;  if ($this->user) { $request .= “Authorization: Basic “.base64_encode(“$this->user:$this->pass”).”rn”;  } if($post_data) { $request .= “Content-Length: “.strlen($post_data).”rnrn”;  $request .= “$post_datarn”; }  else { $request .= “rn”; } fwrite($s, $request);  $response = “”;  while(!feof($s)) { $response .= fgets($s); } list($this->headers, $this->body) = explode(“rnrn”, $response);  return $this->body; } } ?> 

2) Access CouchDB

We can use http://localhost:5984/_utilsto see available databases.
