solr-php-client

A 3rd party PHP library for indexing and searching documents within an Apache Solr installation.
Zip / Tarballs can be found at SolrPhpClient

• Adding, Deleting (by id and query), committing, optimizing and of course searching against a Solr instance
  
• Written for PHP 5 in Zend Framework / PEAR coding style
  
• PHPDoc generated API documentation included
  
• See link above for example usage and further documentation
  

Apache Solr PHP Extension

The Apache Solr PECL extension is a light-weight, feature-rich library that allows developers using Apache Solr via PHP to communicate easily and efficiently with the Solr web service using an object-oriented API.
The documentation for the PECL extension contains instructions on how to install the extension and is available in the PHP Manual under Search Engine Extensions.
Sometimes, the official documentation may take a while to update. The documentation for the Solr PECL extension is constantly being updated from time to time.
If you are unable to find some information on the official PHP manual, please check here
The latest version of the PECL extension is 0.9.7 (2009-11-17)
The php extension can be downloaded from the Apache Solr PECL project home page.
Thanks to Pierre-Alain Joye from php.net, the Windows DLL for php 5.3 can be downloaded here

A quick list of some of the features of the API include :

• Built in support for adding, deleting, optimizing, searching, rollback.
  
• Ability to connect to Solr servers behind SSL-enabled containers.
  
• Users can optionally provide PEM-formatted private keys or certificates to connect in HTTPS mode.
  
• Users can optionally provide CA certificates to authenticate hostname and issuer of SSL certificate.
  
• 
  Developers can now update the values of the servlets (such as search, update) after the SolrClient instance has been created.
  
  
• Built in, Serializable query string builder objects which effectively simplifies the manipulation of name-value pair request parameters across repeated requests.
  
• 
  The query builder API has methods to add/set, remove or retrieve name-value pair values for the following features in Solr : SimpleFacetParameters,StatsComponent, MoreLikeThis, HighlightingParameters, TermsComponent etc.
  
  
• Ability to reuse of HTTP connections across repeated requests (within the same thread in ZTS mode or same process in non-ZTS mode).
  
• Advanced HTTP client that provides built-in support for connecting to Solr servers secured behind HTTP Authentication or HTTP proxy servers.
  
• 
  Ability to obtain SolrInputDocument objects from SolrDocument in query response for possible resubmission or updates.
  
  
• Automatic parsing of Solr response into native php objects whose properties can be accessed as array keys or object properties without any additional configuration on the client-side. This is simplified interface to access server response data. Solr Objects can be treated as arrays or objects.
  
• 
  Also the SolrDocument retrieved from the query response implements the following interfaces which gives the developer several options on how to manipulate the response : ArrayAccess, Iterator, Traversable, Serializable.
  
  

The extension currently uses version 2.2 of the xml response format internally.
The contents of the XML response is transformed into native PHP types and the result is returned as a Solr Object instance.
You may also install it by running the following command in the console :
$ pecl install solr-beta


Solarium

Solarium is a Solr client library for PHP applications that not only facilitates Solr communication but also tries to accurately model Solr concepts.


Solr's PHP response format

Solr has a PHP response format that outputs an array (as PHP code) which can be eval'd.
Example usage:


$code = file_get_contents('http://localhost:8983/solr/select?q=iPod&wt=php');
eval("\$result = " . $code . ";");
print_r($result);


Solr's PHP Serialized response format

Solr has a PHP response format that outputs a serialized array.
Example usage:


$serializedResult = file_get_contents('http://localhost:8983/solr/select?q=iPod&wt=phps');
$result = unserialize($serializedResult);
print_r($result);
In order to use either PHP or Serialized PHP Response Writers, you may first need to uncomment these two lines in your solrconfig.xml:




You can also use the new response writer plugin for PHP here
