Use the select method of the client to execute the select query object.

See the example code below.

<?php

require_once __DIR__.'/init.php';

htmlHeader();

// create a client instance
$client = new Solarium\Client($adapter, $eventDispatcher, $config);

// get a select query instance
$query = $client->createSelect();

// this executes the query and returns the result
$resultset = $client->select($query);

// display the total number of documents found by Solr
echo 'NumFound: '.$resultset->getNumFound();

// show documents using the resultset iterator
foreach ($resultset as $document) {
    echo '<hr/><table>';

    // the documents are also iterable, to get all fields
    foreach ($document as $field => $value) {
        // this converts multivalue fields to a comma-separated string
        if (is_array($value)) {
            $value = implode(', ', $value);
        }

        echo '<tr><th>'.$field.'</th><td>'.$value.'</td></tr>';
    }

    echo '</table>';
}
