    <p>Alright I am still learning my functions in php but this particular piece of code has me stuck. Credit goes to <a href="http://www.barattalo.it/2010/08/29/php-bot-to-get-wikipedia-definitions/" rel="nofollow">http://www.barattalo.it/2010/08/29/php-bot-to-get-wikipedia-definitions/</a> for the wikipedia query segment. I thought this looked interesting and am trying to use the code provided to echo data from the function. This is what I have:</p> <pre><code>&lt;?php function wikidefinition($s) { $url = "http://wikipedia.org/w/api.php?action=opensearch&amp;search=".urlencode($s)."&amp;format=xml&amp;limit=1"; $ch = curl_init($url); curl_setopt($ch, CURLOPT_HTTPGET, TRUE); curl_setopt($ch, CURLOPT_POST, FALSE); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_NOBODY, FALSE); curl_setopt($ch, CURLOPT_VERBOSE, FALSE); curl_setopt($ch, CURLOPT_REFERER, ""); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); curl_setopt($ch, CURLOPT_MAXREDIRS, 4); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 6.1; he; rv:1.9.2.8) Gecko/20100722 Firefox/3.6.8"); $page = curl_exec($ch); $xml = simplexml_load_string($page); if((string)$xml-&gt;Section-&gt;Item-&gt;Description) { return array((string)$xml-&gt;Section-&gt;Item-&gt;Text, (string)$xml-&gt;Section-&gt;Item-&gt;Description, (string)$xml-&gt;Section-&gt;Item-&gt;Url); } else { return "blank"; } } $define = wikidefinition("test"); echo $define; ?&gt; </code></pre> <p>however this simply echos "array" I know the code is getting to the if/else statement because if you change the input in "$define = wikidefinition("test");" to some random key combination such as "qoigenqnge" it will echo "blank" I cannot figure out why it is only echoing "array" instead of the data inside the array. Probably something stupid, but I have been reading up on arrays for a while and cant find any info. Any help will be great thanks!</p>

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.
