我正在编写一些JavaScript代码，该代码使用PHP渲染的字符串.如何在PHP字符串中转义单引号(和仅单引号)?

I am writing some JavaScript code that uses a string rendered with PHP. How can I escape single quotes (and only single quotes) in my PHP string?

<script type="text/javascript"> $('#myElement').html('say hello to <?php echo $mystringWithSingleQuotes ?>'); </script>

推荐答案

很简单:echo str_replace('\'', '\\\'', $myString); 但是，我建议使用 JSON 和 json_encode() 函数，因为它将更加可靠(例如，引用新行):

Quite simply: echo str_replace('\'', '\\\'', $myString); However, I'd suggest use of JSON and json_encode() function as it will be more reliable (quotes new lines for instance):

<?php $data = array('myString' => '...'); ?> <script> var phpData = <?php echo json_encode($data) ?>; alert(phpData.myString); </script>
