PHP OAI-PMH client with a clean API

php-oai-pmh-client

Simple PHP client package for fetching data from an OAI-PMH server, using the Guzzle HTTP client. The returned data is parsed by QuiteSimpleXMLElement.

On network problems, the client will retry a configurable number of times, emitting a request.error event each time, before finally throwing a ConnectionError.

Install using Composer

composer require scriptotek/oai-pmh-client

Example

require_once('vendor/autoload.php');
use Scriptotek\OaiPmh\Client as OaiPmhClient;

$url = 'http://oai.bibsys.no/repository';

$client = new OaiPmhClient($url, array(
    'schema' => 'marcxchange',
    'user-agent' => 'MyTool/0.1',
    'max-retries' => 10,
    'sleep-time-on-error' => 30,
));

Fetching a single record

try {
    $record = $client->record('oai:bibsys.no:biblio:113889372');
} catch (Scriptotek\OaiPmh\ConnectionError $e) {
    echo $e->getMsg();
    die;
} catch (Scriptotek\OaiPmh\BadRequestError $e) {
    echo 'Bad request: ' . $e->getMsg() . "\n";
    die;
}

echo $record->identifier . "\n";
echo $record->datestamp . "\n";
echo $record->data->asXML() . "\n";

Iterating over a record set

foreach ($client->records('') as $record) {
	echo $record->identifier . "\n";
	echo $record->datestamp . "\n";
}

Events

$client->on('request.start', function($verb) {
    print "Starting " . $verb . " request\n";
});
$client->on('request.error', function($err) {
    print "Non-fatal error: " . $err . "\n";
});
$client->on('request.complete', function($verb) {
    print "Completed " . $verb . " request\n";
});

API documentation

API documentation can be generated using e.g. Sami, which is included in the dev requirements of composer.json.

php vendor/bin/sami.php update sami.config.php -v
