    <p>Good day,</p> <p>I am retrieving information from various websites using cURL and various parsing techniques. I made the code so I can, if desired, add additional websites I scan information from.</p> <p>The information retrieved is as follow : (Please note that the information may be inaccurate and may not reflect real price/name)</p> <pre><code>Array ( [website1.com] =&gt; Array ( [0] =&gt; Array ( [0] =&gt; 60" BRAVIA LX900 Series 3D HDTV [1] =&gt; website1.com [2] =&gt; 5299.99 ) [1] =&gt; Array ( [0] =&gt; 52" BRAVIA LX900 Series 3D HDTV [1] =&gt; website1.com [2] =&gt; 4499.99 ) [2] =&gt; Array ( [0] =&gt; 46" BRAVIA LX900 Series 3D HDTV [1] =&gt; website1.com [2] =&gt; 3699.99 ) [3] =&gt; Array ( [0] =&gt; 40" BRAVIA LX900 Series 3D HDTV [1] =&gt; website1.com [2] =&gt; 2999.99 ) ) [website2.com] =&gt; Array ( [0] =&gt; Array ( [0] =&gt; Sony 3D 60" LX900 HDTV BRAVIA [1] =&gt; website2.com [2] =&gt; 5400.99 ) [1] =&gt; Array ( [0] =&gt; Sony 3D 52" LX900 HDTV BRAVIA [1] =&gt; website2.com [2] =&gt; 4699.99 ) [2] =&gt; Array ( [0] =&gt; Sony 3D 46" LX900 HDTV BRAVIA [1] =&gt; website2.com [2] =&gt; 3899.99 ) ) ) </code></pre> <p>The desired output must be : </p> <pre><code>Array ( [0] =&gt; Array ( [Name] =&gt; 60" BRAVIA LX900 Series 3D HDTV [website1.com] =&gt; 5299.99 [website2.com] =&gt; 5400.99 ) [1] =&gt; Array ( [Name] =&gt; 52" BRAVIA LX900 Series 3D HDTV [website1.com] =&gt; 4499.99 [website2.com] =&gt; 4699.99 ) [2] =&gt; Array ( [Name] =&gt; 46" BRAVIA LX900 Series 3D HDTV [website1.com] =&gt; 3699.99 [website2.com] =&gt; 3899.99 ) [3] =&gt; Array ( [Name] =&gt; 40" BRAVIA LX900 Series 3D HDTV [website1.com] =&gt; 2999.99 ) ) </code></pre> <p>Please note that the name may vary so using similar_text is required. Also, some information may not be shown in all websites. I am aware that only one television name must be choosed, then I will use the one from the most relevent source (website1.com)</p> <p>Here is the codes I'm trying to make work.</p> <pre><code>&lt;?php $_Retreived = array( "website1.com" =&gt; array( array('60" BRAVIA LX900 Series 3D HDTV', 'website1.com', 5299.99), array('52" BRAVIA LX900 Series 3D HDTV', 'website1.com', 4499.99), array('46" BRAVIA LX900 Series 3D HDTV', 'website1.com', 3699.99), array('40" BRAVIA LX900 Series 3D HDTV', 'website1.com', 2999.99) ), "website2.com" =&gt; array( array('Sony 3D 60" LX900 HDTV BRAVIA', 'website2.com', 5400.99), array('Sony 3D 52" LX900 HDTV BRAVIA', 'website2.com', 4699.99), array('Sony 3D 46" LX900 HDTV BRAVIA', 'website2.com', 3899.99), ) ); $_Prices = array(); $_PricesTemp = array(); $_Sites = array("website1.com", "website2.com"); for($i = 0; $i &lt; sizeOf($_Sites); $i++) { $_PricesTemp = array_merge($_PricesTemp, $_Retreived[ $_Sites[$i] ]); } /* print_r($_PricesTemp); Array ( [0] =&gt; Array ( [0] =&gt; 60" BRAVIA LX900 Series 3D HDTV [1] =&gt; website1.com [2] =&gt; 5299.99 ) [1] =&gt; Array ( [0] =&gt; 52" BRAVIA LX900 Series 3D HDTV [1] =&gt; website1.com [2] =&gt; 4499.99 ) [2] =&gt; Array ( [0] =&gt; 46" BRAVIA LX900 Series 3D HDTV [1] =&gt; website1.com [2] =&gt; 3699.99 ) [3] =&gt; Array ( [0] =&gt; 40" BRAVIA LX900 Series 3D HDTV [1] =&gt; website1.com [2] =&gt; 2999.99 ) [4] =&gt; Array ( [0] =&gt; Sony 3D 60" LX900 HDTV BRAVIA [1] =&gt; website2.com [2] =&gt; 5400.99 ) [5] =&gt; Array ( [0] =&gt; Sony 3D 52" LX900 HDTV BRAVIA [1] =&gt; website2.com [2] =&gt; 4699.99 ) [6] =&gt; Array ( [0] =&gt; Sony 3D 46" LX900 HDTV BRAVIA [1] =&gt; website2.com [2] =&gt; 3899.99 ) ) */ foreach($_PricesTemp As $_KeyOne =&gt; $_EntryOne) { foreach(array_reverse($_PricesTemp, true) As $_KeyTwo =&gt; $_EntryTwo) { if ($_KeyOne != $_KeyTwo) { $_Percent = 0; similar_text(strtoupper($_EntryOne[0]), strtoupper($_EntryTwo[0]), $_Percent); if ($_Percent &gt;= 90) //If names matches 90%+ { echo "Similar : &lt;b&gt;" . $_KeyOne .

There must be a logical error somewhere that I can't put my finger on. Also, I don't believe the code will work in case I add a third website to the listing.</p> <p>Any ideas guys? I have been on this since this morning.</p> <p><strong>Edit 2011-02-16:</strong></p> <p>I added a bounty to this question.</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.
