Examples
Examples of how to use the Apache Solr extension in PHP
Example #1 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 #2 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 #3 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 #4 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 #5 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 ) ) ) )

$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 ) ) )

if your path to solr is something other than: /solr
you should add this to the bootstrap file above:
define('SOLR_SERVER_PATH', 'my-solr-url');
and then a corresponding entry to the options array in your client php code like:
'path' => SOLR_SERVER_PATH
I couldn't find this is in the documentation and had to peek at the source to figure it out.
If you're testing these examples on a fresh install of solr, you will need to run a commit statement after you add documents to receive results when searching.
For example, add this:
<?php $client->commit(); ?>
to example 3 to be able to get any results when doing a search using example 5.
If you like to access a different RequestHander than '/select' you can change it via solrclient.setservlet
If you are using Solr's multicore feature, you can access the cores via the path parameter in the $options array.
E.g.
<?php
$options = array(...., 'path' => 'solr/core0', ...);
?>
The documentation in the example section doesn't mention that you need to commit once you've added doc(s).
So in short it would be something like:
$client = new SolrClient(array('hostname' => '127.0.0.1', 'port' => 8080));
$doc = new SolrInputDocument();
$doc->addField('id', 12345);
$doc->addField('name', 'some person');
$result = $client->addDocument($doc);
/* you are not done yet, you need to commit */
$client->commit();
Now if you query you should see your doc =]
As of solr 4.0 the waitFlush parameter is removed.
Source
http://wiki.apache.org/solr/UpdateXmlMessages
$client->commit() throws an error
[SolrClientException]
Unsuccessful update request. Response Code 400. <?xml version="1.0" encoding="UTF-8"?>
<response>
<lst name="responseHeader">
<int name="status">400</int>
<int name="QTime">1</int>
</lst>
<lst name="error">
<str name="msg">Unknown commit parameter 'waitFlush'</str>
<int name="code">400</int>
</lst>
</response>
As of solr 4.0 the waitFlush parameter is removed.
If you're using the solr 4.0 or later version (and you have to),when you do this
<?php $client->commit(); ?>
you will get a solr error like this:
"Unknown commit parameter 'waitFlush'."
If you insist on using this PHP Solr extension and solr 4.0 or later version,you can edit the extension's source (version 1.0.2) php_solr_client.c.
for the SolrClient's optimize method:
at line 1490 :
zend_bool waitFlush = 1, waitSearcher = 1;
after edited:
zend_bool waitSearcher = 1;
at line 1493:
char *waitFlushValue, *waitSearcherValue;
after edited:
zend_bool waitSearcher = 1;
at line 1502:
if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "|sbb", &maxSegments, &maxSegmentsLen, &waitFlush, &waitSearcher) == FAILURE) {
after editd:
if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "|sb", &maxSegments, &maxSegmentsLen, &waitSearcher) == FAILURE) {
remove the line 1509 and 1515.
And do the same edit for the SolrClient's commit method at line 1561,1564,1573 and remove the line 1580,1586
The final step, compile the code and install it.
Good luck!
In case someone would like to use this solrClient with solr v.4.0 and higher i've prepared my own commit function
class solr {
public function delete($query ) {
$this->_client->deleteByQuery($query);
$this->commit();
}
public function commit() {
$solrConfig= // array with solr host, port, path to collection (/solr/my_collection),
$solrAddress = $solrConfig['hostname'] . ':' . $solrConfig['port'] . $solrConfig['path'];
$output = array();
$response = exec('curl ' . $solrAddress . '/update?commit=true', $output);
return $output;
}
}
