PHP CouchDB Extension

The CouchDB extension allows PHP developers to easily manipulate CouchDB documents stored on CouchDB servers using an object-oriented API. The extension implements most of the CouchDB API with the ultimate goal being full support. The server JSON responses are automatically decoded into native PHP objects or arrays.

This is a staging page at the moment, efforts are underway to move development to PECL

• Supports the largest part of the CouchDB API (Database API, Document API, View API, Bulk Document API).
• Supports both Cookie and Basic authentication.
• Supports built in encoding and decoding of JSON.
• Supports replication.
• Supports server functions (configuration, status, stats).
• Supports user management.

Download

• Download the source
• run the command “pecl install couchdb-0.0.2a.tgz”
• Add “extension=couchdb.so” to your php.ini file

• Download the source
• Unpack the tarball tar xzvf couchdb-0.0.2a.tgz
• Enter the source directory and run “phpize && ./configure && make && make install”
• Add “extension=couchdb.so” to your php.ini file.

• Download the source
• Unpack the tarball to the PHP extensions dir “tar xzvf couchdb-0.0.2a.tgz -C $PHP_SOURCE/ext/”
• Reconfigure the PHP source “rm configure && ./buildconf –force”
• Configure php with ”./configure –enable-couchdb”

The documentation is still a work in progress can be found here, help in expanding the documentation is welcome.

The following example is included in the source tarball, provides some guideline on using the extension.

/* Create the CouchdbClient object
 The url can support authentication as well 
 - http://user:password@localhost:5984
 
 - Authentication is both by basic and cookie
 To use cookie authentication you need to set use_cookie_auth to true
  CouchdbClient("http://user:pass@localhost:5984",true);
 
 
 The url could be https
 - https://localhost:5984
 You may have to set the CA info using CouchdbClient::setCAPath()
