    <p>But of a confusing title so let me explain. I have an array of links like this:</p> <pre><code>http://somesite.com/videoplayback?ip=81.0.0.0&amp;sparams=id,expire,ip,ipbits,itag,algorithm,burst,factor&amp;fexp=905602&amp;algorithm=throttle-factor&amp;itag=34&amp;ipbits=8&amp;burst=40&amp;sver=3&amp;expire=1285056000&amp;key=yt1&amp;signature=690F9475D5288F3129F84364427B2B490B6ACE59.45C8F83DEE3DD361855B12AE538EA6349FF8EF9B&amp;factor=1.25&amp;id=d50e6528eb51ad54,18 http://somesite.com/videoplayback?ip=81.0.0.0&amp;sparams=id,expire,ip,ipbits,itag,algorithm,burst,factor&amp;fexp=905602&amp;algorithm=throttle-factor&amp;itag=18&amp;ipbits=8&amp;burst=40&amp;sver=3&amp;expire=1285056000&amp;key=yt1&amp;signature=A68EAA3F7A2ECA2BB2BD6C35BF443C03E4BB1172.AD2FF9FDAF046B23F789FE1A7F7882DF9A355DE4&amp;factor=1.25&amp;id=d50e6528eb51ad54,5 http://somesite.com/videoplayback?ip=81.0.0.0&amp;sparams=id,expire,ip,ipbits,itag,algorithm,burst,factor&amp;fexp=905602&amp;algorithm=throttle-factor&amp;itag=5&amp;ipbits=8&amp;burst=40&amp;sver=3&amp;expire=1285056000&amp;key=yt1&amp;signature=ABC8ACF6899C46CC992ECB5F6A6FD7E66383EA3D.0C8B707083203DC1153FB26586A94BFAC64D176B&amp;factor=1.25&amp;id=d50e6528eb51ad54 </code></pre> <p>If you look at the very end of those URL's, they have extensions like <code>,18</code>, <code>,5</code> and there is one last link with no extension like this at all.</p> <p>Now, I need to use the link that has the highest number on the end as possible later in my code. In this example I need to filter out the very first link, because it has the highest integer on the end (<code>18</code>).</p> <p>I would use a series of <code>if()</code> blocks, but in this case the integers on the end can change so that's not a good solution.</p> <p>So I basically need to go through my array, check which link has the highest integer at the end (note that it is only 2 digits in length) and then store it in another variable.</p> <p>Can anyone provide some sample/psudo code on how to effectively do this?</p> <p>Cheers.</p>

    1. CODamn, if it wasn't for the 'can have nothing', we could employ an überevil `max(array_map('intval',array_map('strrev',array_map('intval',array_map('strrev',$array)))));`

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.
