As noted in the comments, you need one of the following:
- PHP version >= 5.2 (includes the json_decode function by default)
- The JSON module installed through PECL (still requires PHP 5 but
can work with lesser versions)
- a defined json_decode function alternative, for example, the Zend
framework has a Zend_Json class with a decode function. You could
replace the json_decode call with a call to this class, or you could
take it as an example for defining your own. I'm sure PEAR has some
JSON decoding libraries as well.
the client will probably not work without PHP 5 and definitely will
not work with the json_decode function as you've found out

Asunto: [jira] Updated: (SOLR-341) PHP Solr Client
[ https://issues.apache.org/jira/browse/SOLR-341?
page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Donovan Jimenez updated SOLR-341:
---------------------------------
Attachment: SolrPhpClient.zip
Updates to the Solr Client:
- search can now take muliple parameters of the same name, such as
when using facets
- ping now can take a timeout value which acts as a maximum time
allowed to wait for a response
- namespace change to Apache_Solr to avoid confusion with php
Solar (unrelated) project
- Apache_Solr_Document now implements iterator interface, so its
fields can be foreach'd
- Reference implementation of a read from slave / write to master
balancer has be added
PHP Solr Client
---------------
Key: SOLR-341
URL: https://issues.apache.org/jira/browse/SOLR-341
Project: Solr
Issue Type: New Feature
Components: clients - php
Affects Versions: 1.2
Environment: PHP >= 5.2.0 (or older with JSON PECL
extension or other json_decode function implementation). Solr >= 1.2
Reporter: Donovan Jimenez
Priority: Trivial
Attachments: SolrPhpClient.zip, SolrPhpClient.zip
Developed this client when the example PHP source didn't meet our
needs. The company I work for agreed to release it under the
terms of the Apache License.
This version is slightly different from what I originally linked
to on the dev mailing list. I've incorporated feedback from Yonik
and "hossman" to simplify the client and only accept one response
format (JSON currently).
When Solr 1.3 is released the client can be updated to use the PHP
or Serialized PHP response writer.
example usage from my original mailing list post:
<?php
require_once('Solr/Service.php');
$start = microtime(true);
$solr = new Solr_Service(); //Or explicitly new Solr_Service
('localhost', 8180, '/solr');
try
{
$response = $solr->search('solr', 0, 10,
array(/* you can include other parameters here */));
echo 'search returned with status = ', $response-
>responseHeader->status,
' and took ', microtime(true) - $start, '
seconds', "\n";
//here's how you would access results
//Notice that I've mapped the values by name into a tree
of stdClass objects
//and arrays (actually, most of this is done by json_decode )
if ($response->response->numFound > 0)
{
$doc_number = $response->response->start;
foreach ($response->response->docs as $doc)
{
$doc_number++;
echo $doc_number, ': ', $doc->text, "\n";
}
}
//for the purposes of seeing the available structure of
the response
//NOTE: Solr_Response::_parsedData is lazy loaded, so a
print_r on the response before
//any values are accessed may result in different behavior
(in case
//anyone has some troubles debugging)
//print_r($response);
}
catch (Exception $e)
{
echo $e->getMessage(), "\n";
}
?>
