Examples of how to use the Apache Solr extension in PHP
Example #2 Contents of the BootStrap file
<?php
/* Domain name of the Solr server */
define('SOLR_SERVER_HOSTNAME', 'solr.example.com');
/* Whether or not to run in secure mode */
define('SOLR_SECURE', true);
/* HTTP Port to connection */
define('SOLR_SERVER_PORT', ((SOLR_SECURE) ? 8443 : 8983));
/* HTTP Basic Authentication Username */
define('SOLR_SERVER_USERNAME', 'admin');
/* HTTP Basic Authentication password */
define('SOLR_SERVER_PASSWORD', 'changeit');
/* HTTP connection timeout */
/* This is maximum time in seconds allowed for the http data transfer operation. Default value is 30 seconds */
define('SOLR_SERVER_TIMEOUT', 10);
/* File name to a PEM-formatted private key + private certificate (concatenated in that order) */
define('SOLR_SSL_CERT', 'certs/combo.pem');
/* File name to a PEM-formatted private certificate only */
define('SOLR_SSL_CERT_ONLY', 'certs/solr.crt');
/* File name to a PEM-formatted private key */
define('SOLR_SSL_KEY', 'certs/solr.key');
/* Password for PEM-formatted private key file */
define('SOLR_SSL_KEYPASSWORD', 'StrongAndSecurePassword');
/* Name of file holding one or more CA certificates to verify peer with*/
define('SOLR_SSL_CAINFO', 'certs/cacert.crt');
/* Name of directory holding multiple CA certificates to verify peer with */
define('SOLR_SSL_CAPATH', 'certs/');

Example #3 Adding a document to the index
<?php
include "bootstrap.php";
$options = array
(
'hostname' => SOLR_SERVER_HOSTNAME,
'login' => SOLR_SERVER_USERNAME,
'password' => SOLR_SERVER_PASSWORD,
'port' => SOLR_SERVER_PORT,
);
$client = new SolrClient($options);
$doc = new SolrInputDocument();
$doc->addField('id', 334455);
$doc->addField('cat', 'Software');
$doc->addField('cat', 'Lucene');
$updateResponse = $client->addDocument($doc);
print_r($updateResponse->getResponse());
?>
The above example will output something similar to:
SolrObject Object ( [responseHeader] => SolrObject Object ( [status] => 0 [QTime] => 446 ) )
Example #4 Merging one document into another document
<?php
include "bootstrap.php";
$doc = new SolrDocument();
$second_doc = new SolrDocument();
$doc->addField('id', 1123);
$doc->features = "PHP Client Side";
$doc->features = "Fast development cycles";
$doc['cat'] = 'Software';
$doc['cat'] = 'Custom Search';
$doc->cat = 'Information Technology';
$second_doc->addField('cat', 'Lucene Search');
$second_doc->merge($doc, true);
print_r($second_doc->toArray());
?>
The above example will output something similar to:
Array ( [document_boost] => 0 [field_count] => 3 [fields] => Array ( [0] => SolrDocumentField Object ( [name] => cat [boost] => 0 [values] => Array ( [0] => Software [1] => Custom Search [2] => Information Technology ) ) [1] => SolrDocumentField Object ( [name] => id [boost] => 0 [values] => Array ( [0] => 1123 ) ) [2] => SolrDocumentField Object ( [name] => features [boost] => 0 [values] => Array ( [0] => PHP Client Side [1] => Fast development cycles ) ) ) )
Example #5 Searching for documents - SolrObject responses
<?php
include "bootstrap.php";
$options = array
(
'hostname' => SOLR_SERVER_HOSTNAME,
'login' => SOLR_SERVER_USERNAME,
'password' => SOLR_SERVER_PASSWORD,
'port' => SOLR_SERVER_PORT,
);
$client = new SolrClient($options);
$query = new SolrQuery();
$query->setQuery('lucene');
$query->setStart(0);
$query->setRows(50);
$query->addField('cat')->addField('features')->addField('id')->addField('timestamp');
$query_response = $client->query($query);
$response = $query_response->getResponse();
print_r($response);
?>
The above example will output something similar to:
SolrObject Object ( [responseHeader] => SolrObject Object ( [status] => 0 [QTime] => 1 [params] => SolrObject Object ( [wt] => xml [rows] => 50 [start] => 0 [indent] => on [q] => lucene [fl] => cat,features,id,timestamp [version] => 2.2 ) ) [response] => SolrObject Object ( [numFound] => 3 [start] => 0 [docs] => Array ( [0] => SolrObject Object ( [cat] => Array ( [0] => Software [1] => Lucene ) [id] => 334456 ) [1] => SolrObject Object ( [cat] => Array ( [0] => Software [1] => Lucene ) [id] => 334455 ) [2] => SolrObject Object ( [cat] => Array ( [0] => software [1] => search ) [features] => Array ( [0] => Advanced Full-Text Search Capabilities using Lucene [1] => Optimized for High Volume Web Traffic [2] => Standards Based Open Interfaces - XML and HTTP [3] => Comprehensive HTML Administration Interfaces [4] => Scalability - Efficient Replication to other Solr Search Servers [5] => Flexible and Adaptable with XML configuration and Schema [6] => Good unicode support: héllo (hello with an accent over the e) ) [id] => SOLR1000 [timestamp] => 2009-09-04T20:38:55.906 ) ) ) )
Example #6 Searching for documents - SolrDocument responses
<?php
include "bootstrap.php";
$options = array
(
'hostname' => SOLR_SERVER_HOSTNAME,
'login' => SOLR_SERVER_USERNAME,
'password' => SOLR_SERVER_PASSWORD,
'port' => SOLR_SERVER_PORT,
);
$client = new SolrClient($options);
$query = new SolrQuery();
$query->setQuery('lucene');
$query->setStart(0);
$query->setRows(50);
$query->addField('cat')->addField('features')->addField('id')->addField('timestamp');
$query_response = $client->query($query);
$query_response->setParseMode(SolrQueryResponse::PARSE_SOLR_DOC);
$response = $query_response->getResponse();
print_r($response);
?>
The above example will output something similar to:
SolrObject Object ( [responseHeader] => SolrObject Object ( [status] => 0 [QTime] => 1 [params] => SolrObject Object ( [wt] => xml [rows] => 50 [start] => 0 [indent] => on [q] => lucene [fl] => cat,features,id,timestamp [version] => 2.2 ) ) [response] => SolrObject Object ( [numFound] => 3 [start] => 0 [docs] => Array ( [0] => SolrDocument Object ( [_hashtable_index:SolrDocument:private] => 19740 ) [1] => SolrDocument Object ( [_hashtable_index:SolrDocument:private] => 25485 ) [2] => SolrDocument Object ( [_hashtable_index:SolrDocument:private] => 25052 ) ) ) )
Example #7 Simple TermsComponent example - basic
<?php
include "bootstrap.php";
$options = array
(

'login' => SOLR_SERVER_USERNAME,
'password' => SOLR_SERVER_PASSWORD,
'port' => SOLR_SERVER_PORT,
);
$client = new SolrClient($options);
$query = new SolrQuery();
$query->setTerms(true);
$query->setTermsField('cat');
$updateResponse = $client->query($query);
print_r($updateResponse->getResponse());
?>
The above example will output something similar to:
SolrObject Object ( [responseHeader] => SolrObject Object ( [status] => 0 [QTime] => 2 ) [terms] => SolrObject Object ( [cat] => SolrObject Object ( [electronics] => 14 [Lucene] => 4 [Software] => 4 [memory] => 3 [card] => 2 [connector] => 2 [drive] => 2 [graphics] => 2 [hard] => 2 [monitor] => 2 ) ) )
Example #8 Simple TermsComponent example - using a prefix
<?php
include "bootstrap.php";
$options = array
(
'hostname' => SOLR_SERVER_HOSTNAME,
'login' => SOLR_SERVER_USERNAME,
'password' => SOLR_SERVER_PASSWORD,
'port' => SOLR_SERVER_PORT,
);
$client = new SolrClient($options);
$query = new SolrQuery();
$query->setTerms(true);
/* Return only terms starting with $prefix */
$prefix = 'c';
$query->setTermsField('cat')->setTermsPrefix($prefix);
$updateResponse = $client->query($query);
print_r($updateResponse->getResponse());
?>
The above example will output something similar to:

Example #9 Simple TermsComponent example - specifying a minimum frequency
<?php
include "bootstrap.php";
$options = array
(
'hostname' => SOLR_SERVER_HOSTNAME,
'login' => SOLR_SERVER_USERNAME,
'password' => SOLR_SERVER_PASSWORD,
'port' => SOLR_SERVER_PORT,
);
$client = new SolrClient($options);
$query = new SolrQuery();
$query->setTerms(true);
/* Return only terms starting with $prefix */
$prefix = 'c';
/* Return only terms with a frequency of 2 or greater */
$min_frequency = 2;
$query->setTermsField('cat')->setTermsPrefix($prefix)->setTermsMinCount($min_frequency);
$updateResponse = $client->query($query);
print_r($updateResponse->getResponse());
?>
The above example will output something similar to:

$updateResponse = $client->query($query);
$response_array = $updateResponse->getResponse();
$facet_data = $response_array->facet_counts->facet_fields;
print_r($facet_data);
