    <p>A high level overview should be like this:</p> <ul> <li>create the end result array $items</li> <li>loop through all the found items in all the websites</li> <li>for each one, check if it's similar enough to any of the existing item names in $items</li> <li>if yes, then add the price to that key, if no then create a new one and add it there</li> </ul> <p>Instead of <code>similar_text()</code> you should consider using <code>levenshtein()</code> which is similar in practice but quite faster.</p> <p>Here's some (untested, on the spot) code:</p> <pre><code>$levThreshold = 3 ; $_Prices = array() ; foreach ($_Retreived as $website =&gt; $websiteItems) { $currName = $websiteItems[0] ; $currWebsite = $websiteItems[1] ; $currPrice = $websiteItems[2] ; $foundItemKey = false ; //check current price structure. Get $priceData by reference //so we can modify it in the loop and keep the changed instead //of the loop copy. foreach ($_Prices as &amp;$priceData) { if (isset($priceData[$website])) { //already done this continue ; } //check if this is the item name we are looping over $lev = levenshtein($priceData['Name'], $currName) ; if ($lev &lt; $levThreshold) { //item exists, add price and break $priceData[$website] = $currPrice ; $foundItemKey = true ; break ; } } //if we haven't found the item key, create a new one if (!$foundItemKey) { $newItem = array() ; $newItem['Name'] = $currName ; $newItem[$website] = $currPrice ; $_Prices[] = $newItem ; } } </code></pre> <p><code>$levThreshold</code> is the minimum number of characters that must be different between 2 strings for them to be considered different. You can tweak that accordingly.</p>

    1. COHi Fanis, I know you answered without testing. But your code isn't working. No error but there must be a logical issue somewhere. I'm trying to fix it but with no success really. Thank you about the levenshtein I wasnt aware of it's existence.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
