Highlighting search results in php / mysql

Question

How to extract search results from mysql query using php?

this is my [modified] code:

$search_result = "";

$search_result = $_GET["q"];

$result = mysql_query('SELECT cQuotes, vAuthor, cArabic, vReference FROM thquotes WHERE cQuotes LIKE "%' . $search_result .'%" ORDER BY idQuotes DESC', $conn)
  or die ('Error: '.mysql_error());


function h($s) {
    echo htmlspecialchars($s, ENT_QUOTES);
} 


?>

    <div class="caption">Search Results</div>
<div class="center_div">
<table>
    <?php while ($row= mysql_fetch_array($result)) { ?>
    <?php $cQuotes = preg_replace($search_result, "<div class='highlight'>".$search_result."</div>", $row['cQuotes']); ?>
        <tr>
            <td style="text-align:right; font-size:15px;"><?php h($row['cArabic']) ?></td>
            <td style="font-size:16px;"><?php h($cQuotes) ?></td>
            <td style="font-size:12px;"><?php h($row['vAuthor']) ?></td>
            <td style="font-size:12px; font-style:italic; text-align:right;"><?php h($row['vReference']) ?></td>
        </tr>
    <?php } ?>
</table>
</div>

Answer 1

you can use preg_replace (); when it finds a match in your text, you can put a div with a highlight class around the corresponding word. Then you added the background color and border to the selection class to highlight it.

preg_replace expect 3 parameters;

• the first is what you are looking for.
• the second is what should be changed to
• The line of text that it should search for and replace from

eg,

<div class="center_div">
    <table>
    <caption>Search Results</caption>
    <?php while ($row= mysql_fetch_array($result)) { ?>
<?php $arabic = preg_replace("/".$search_result."/", "<div class='highlight'>".$search_result."</div>", h($row['cArabic'])); ?>
            <tr>
                <td style="text-align:right; font-size:15px;"><?php $arabic ?></td>
                <td style="font-size:16px;"><?php h($row['cQuotes']) ?></td>
                <td style="font-size:12px;"><?php h($row['vAuthor']) ?></td>
                <td style="font-size:12px; font-style:italic; text-align:right;"><?php h($row['vReference']) ?></td>
            </tr>
        <?php } ?>
    </table>
    </div>
