Question

我想在网页上替换文本和html字符串。这是为了突出显示文本。因此，突出显示的文本存储在数据库中，当加载其网页时，代码应查找并替换该文本。

例如，

$original_string = "SOME TEXT"; 
$replacement_string = "<span data-id='7334' class='highlight'>SOME TEXT</span>";

我在使用PHP str_replace时遇到了问题，因为它不能替代奇怪的html实体或更大的字符串。

所以现在，我正在尝试使用JS在客户端进行，并且使用js replace（）获得了更好的结果。

我的问题是 - 达到上述目标的最佳方法是什么？我应该使用PHP解析器还是坚持使用JS？

如果我使用JS，我应该如何构造for循环以便所有替换都在同一文本上进行？这不太有效：

var value = $('#domainContainer').html();

    var $highlightsArray_search = <?php echo json_encode($highlightsArray_search); ?>;
    var $highlightsArray_replace = <?php echo json_encode($highlightsArray_replace); ?>;

    for(var i=0; i<2; i++){
        var search_value = $highlightsArray_search[i];
        var replace_value = $highlightsArray_replace[i];

        var formattedSnippet = value.replace(search_value, replace_value);

        value = formattedSnippet;

    }

    $('#domainContainer').html(formattedSnippet);

Answer 2

将你的html代码输入到php字符串中。例如。

<?php
$original_string = "SOME TEXT"; 
$first ="<span data-id='7334' class='highlight'>";
$second = "</span>";
echo $first.$original_string.$second;
?>
