突出显示mysql php搜索中的搜索词

有人可以帮我突破我的PHP 搜索代码中的searchterm吗？
下面是我目前使用的代码,它工作正常.只想添加一个高亮显示功能,但不知道如何在没有重做整个事情的情况下在这段代码上实现它.

我遇到了Highlight search text in mysql php search这个看起来非常好的帖子.但我失去了试图实现这一点.前段时间我有一个< span>效果,但无法进入< table>仅突出显示searchterm并仍在表中循环.

include("config/config.PHP");
$con = MysqL_connect($host, $db_user, $db_pass);
if (!$con)
    {
    die('Could not connect: ' . MysqL_error());
    }

MysqL_select_db($db, $con);

$result = MysqL_query("SELECT * FROM data WHERE `data_id` LIKE '%$_POST[searchterm]%'
OR `who` LIKE '%$_POST[searchterm]%'
OR `ref` LIKE '%$_POST[searchterm]%'
OR `asset` LIKE '%$_POST[searchterm]%'
OR `make_model` LIKE '%$_POST[searchterm]%'
OR `serial` LIKE '%$_POST[searchterm]%'
OR `os` LIKE '%$_POST[searchterm]%'
OR `swp` LIKE '%$_POST[searchterm]%'
OR `ea` LIKE '%$_POST[searchterm]%'
OR `dt_in` LIKE '%$_POST[searchterm]%'
OR `status` LIKE '%$_POST[searchterm]%'
OR `dt_out` LIKE '%$_POST[searchterm]%'
");
$num_rows = MysqL_num_rows($result);

echo "<center>";
echo "<BR><BR>";
echo "<a href='index.PHP'><button id='sblogloginbtn' name='login' type='submit'><b>BACK</b></button></a>";
echo "<BR><BR>";
echo "<h1>Your search has found&nbsp;";
echo "<b><font size='15' color='blue'>$num_rows</font></b>";
echo "&nbsp;records.</font></h1>";
echo "<BR><BR>";

echo "<table border='frame'>
<tr style='color:#FF00FF'>
<th>Signed in By</th>
<th>Reference Number</th>
<th>Asset Number</th>
<th>Make Model</th>
<th>Serial Number</th>
<th>Operating System</th>
<th>Office</th>
<th>Profile</th>
<th>Extra Apps</th>
<th>Time IN</th>
<th>Status</th>
<th>Time OUT</th>
</tr>";

while($row = MysqL_fetch_array($result))
    {
    echo "<tr>";
    echo "<td>" . $row['who'] . "</td>";
    echo "<td>" . $row['ref'] . "</td>";
    echo "<td>" . $row['asset'] . "</td>";
    echo "<td>" . $row['make_model'] . "</td>";
    echo "<td>" . $row['serial'] . "</td>";
    echo "<td>" . $row['os'] . "</td>";
    echo "<td>" . $row['office'] . "</td>";
    echo "<td>" . $row['swp'] . "</td>";
    echo "<td>" . $row['ea'] . "</td>";
    echo "<td>" . $row['dt_in'] . "</td>";
    echo "<td>" . $row['status'] . "</td>";
    echo "<td>" . $row['dt_out'] . "</td>";
    }
echo "</table>";
echo "<br /><br />";
echo "</center>";

MysqL_close($con);

解决方法:

最简单的解决方案是使用str_replace()将搜索项替换为< span>标签缠绕在他们周围,风格.

警告：您设置脚本的方式,您很容易受到注入攻击.这只是向您展示如何传入变量的示例.
