突出搜索文本在mysql php搜索

嗨，这是我的脚本，它很适合搜索我的数据库。我有一个form.html用户在搜索框中输入关键字。突出搜索文本在mysql php搜索

<form method="get" action="form.php"> 
<input type="text" name="searchterm" title="Enter your search term here" value="Enter your search term here" class="searchbox" /> 
<input type="submit" name="search" title="Search Now! "value="Search" class="searchbutton" /> 
</form>

我想突出显示结果中的搜索文本。

千恩万谢

form.php的

试试这个：

$searchvalue = implode('<span style="color:green;font-weight:800;">'.$_GET['searchterm'].'</span>',explode($_GET['searchterm'],$row['PageText'])); 
echo '<div class="rowcontainer"><p><strong>Book Id: 
</strong>'.$row['BookId'].'<p><p><strong>Page Id: 
</strong>'.$row['PageId'].'</p><p><strong>Page Text: 
</strong>'.$searchvalue.'</p></div>'."n";

感谢了很多行之有效 – jk1844

您可以使用此代码：

<?php 
//$keyword -> keyword to be search in string. 
//$field -> string contain value to be seach 
// Returns HTML content with highlighted text 
function makeHighlighter($keyword, $field) { 
    $i = strripos($field, $keyword); 
    if ($i !== false) { 
     $keyword = str_ireplace($keyword, substr($field, $i, (strlen($keyword))), $keyword); 
    } else { 
     return $field; 
    } 
    $as_unm_split = explode($keyword, $field); 
    $string_hig = ""; 
    for ($i = 0; $i < count($as_unm_split); $i++) { 
     if ($i < count($as_unm_split) - 1) 
      $string_hig.=$as_unm_split[$i] . "<span style=\"color: red\">" . $keyword . "</span>"; 
     else 
      $string_hig.=$as_unm_split[$i]; 
    } 
    unset($as_unm_split, $keyword, $i); 
    return $string_hig; 
} 

echo makeHighlighter("keyword","this is keyword to be match..."); 
?>

O/P

这关键字是比赛......

它不支持UTF工作-8个字符。例如'qué'。我如何改进它使其工作？ – Pathros
