    <p>I have been following this tutorial on how to use <code>curl_multi</code>. <a href="http://arguments.callee.info/2010/02/21/multiple-curl-requests-with-php/" rel="noreferrer">http://arguments.callee.info/2010/02/21/multiple-curl-requests-with-php/</a></p> <p>I can't tell what I am doing wrong, but <code>curl_multi_getcontent</code> is returning null. It is suppose to return JSON. I know it is not the mysql call as I had it working with a while loop and standard <code>curl_exec</code>, but The page was taking too long to load. (I've changed some of the setopt details for security)</p> <p><strong>Relevant PHP Code snippet. I do close the while loop in the end.</strong> </p> <pre><code>$i = 0; $ch = array(); $mh = curl_multi_init(); while($row = $result-&gt;fetch_object()){ $ch[$i] = curl_init(); curl_setopt($ch[$i], CURLOPT_CAINFO, 'cacert.pem'); curl_setopt($ch[$i], CURLOPT_USERPWD, "$username:$password"); curl_setopt($ch[$i], CURLOPT_RETURNTRANSFER, true); curl_setopt($ch[$i], CURLOPT_URL, 'https://mysite.com/search/'.$row-&gt;username.'/'); curl_multi_add_handle($mh, $ch[$i]); $i++; } $running = 0; do { curl_multi_exec($mh, $running); } while ($running &gt; 0); $result-&gt;data_seek(0); $i = 0; while ($row = $result-&gt;fetch_object()) { $data = curl_multi_getcontent($ch[$i]); $json_data = json_decode($data); var_dump($json_data); </code></pre> <p><strong>EDIT</strong></p> <p>Here is the code that currently works, but causes the page to load too slowly</p> <pre><code>$ch = curl_init(); curl_setopt($ch, CURLOPT_CAINFO, 'cacert.pem'); curl_setopt($ch, CURLOPT_USERPWD, "$username:$password"); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); while($row = $result-&gt;fetch_object()){ curl_setopt($ch, CURLOPT_URL, 'https://mysite.com/search/'.$row-&gt;username.'/'); $data = curl_exec($ch); $json_data = json_decode($data); var_dump($json_data); } </code></pre>

    1. COCURLOPT_USERPWD assumes you have http password authentication on the website. If it is setup that way, change your code to curl_setopt($ch[$i], CURLOPT_USERPWD, "$username:$password"); with double quotes.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
