<p>I am having difficulty trying to display the top 5 results from a query using PHP with MYSQL. At the minute all the outputs are displaying in descending order but I'm looking to display the top 5 from 10 in descending order. Below is the code I am working with:</p> <pre><code><?php //Footballer $career2sequence1 = mysql_result(mysql_query("SELECT `q1` FROM `careers` WHERE `careerid` = '2'"), 0); ?> <?php $career2result1 = $question1/$career2sequence1; if ($career2result1>1) { $career2result1 = $career2sequence1/$question1 ?> <?php } ?> <?php $careername1 = 'Nursing '; $careername2 = 'Footballer '; $careername3 = 'Dentist '; $careername4 = 'Hairdressing '; $careername5 = 'IT '; $careername6 = 'Trade '; $careername7 = 'Doctor '; $careername8 = 'Teacher '; $careername9 = 'Sales Assistant '; $careername10 = 'Cook/Chef '; ?> <h4> <?php $nursing = array("Nursing", $result1, "% ", "$link1"); $footballer = array("Footballer", $result2, "% ", "$link2"); $dentist = array("Dentist", $result3, "% ", "$link3"); $hairdresser = array("Hairdresser", $result4, "% ", "$link4"); $IT = array("IT", $result5, "% ", "$link5"); $Trade = array("Trade", $result6, "% ", "$link6"); $Doctor = array("Doctor", $result7, "% ", "$link7"); $Teacher = array("Teacher", $result8, "% ", "$link8"); $SalesAssistant = array("Sales Assistant", $result9, "% ", "$link9"); $CookChef = array("Cook/Chef", $result10, "% ", "$link10"); $items = array($nursing, $footballer, $dentist, $hairdresser, $IT, $Trade, $Doctor, $Teacher, $SalesAssistant, $CookChef); foreach ($items as $item) { $item[1].'<-'.$item[0].'<br>';; } function compare($a, $b) { if ($a[1] == $b[1]) { return 0; } return ($a[1] > $b[1]) ? -1 : 1; } usort($items, 'compare'); foreach ($items as $item) { echo implode(' ',$item).'<br>'; } ?> </code></pre>

Guidance

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.
