Dynamic Document Search Engine – Part 2 Page 5

Finally we have to display the results in the browser. Here is the code.

<?php
if(isset($FoundRef)) 
{
    echo "<table width="100%"><tr><th class="title">Search Result</td></tr></table>";
    echo "<br />";
    echo sizeof($FoundRef);
    echo (sizeof($FoundRef) == 1 ? " reference" : " references");
    echo " found";
    if($junkWords)
    {
        echo "Common words like";
        foreach($junkWords as $jWords)
        {
            echo "&nbsp"."'".$jWords."'";
        }
        echo "are removed from the search string";
    }
    echo "</h5>";
    foreach($FoundRef as $a => $value)
    {
        echo "<table>";
        echo "<tr><td valign="top">";
        // echo $FoundRef[$a]["contid"];
        <a href=showref.php?refid=<?php echo $FoundRef[$a]["contid"]?>><emp><b>
        <?php echo $FoundRef[$a]["title"]?></b></emp></a><div align="right">
        Occurance(s): 
        <?php echo $FoundRef[$a]["occurance"] ?></div>
        <br /><small>
        <?php echo $FoundRef[$a]["summary"] ?>...</small>
        <br /><br />
        <?php echo "</td></tr>";
    }?>
    <?php echo "</table>";
}//end of isset FoundRef
?>

Timer to Calculate the Time Taken to Search the Documents:

You can include a timer that calculates the time period to do the search operation. Here is the code.

<?php
//START TIMER
$end=getmicrotime();
//PERFORM SEARCH OPERATION
//END TIMER
$end=getmicrotime();
//TOTAL TIME TAKEN TO DO SEARCH OPERATION
$time_taken=(float)($end-$start);
$time_taken=number_format($time_taken,2,'.','');
?>

The following function calculates the time in microseconds.

<?php
function getmicrotime()
{
    list($usec,$sec)=explode(" ",microtime());
    return ((float)$usec+(float)$sec);
}
?>
