推荐答案
您必须使用htmlentities将引号转换为HTML实体。
You have to use htmlentities to convert the quotes to HTML entities.
$str = htmlentities($str);
http://php.net/manual/en/function.htmlentities.php
像这样使用它：
<form method="post">
Submitter: <input type="text" name="submitter" value="<?= $video['submitter'] ?>" /> <br />
Video Title: <input type="text" name="videoTitle" value="<?= $video['videoTitle'] ?>" /> <br />
Channel Name: <input type="text" name="channelName" value="<?= $video['channelName'] ?>" /> <br />
Video Link: <input type="text" name="videoLink" value="<?= htmlentities($video['videoLink']) ?>" /> <br />
<input type="hidden" name="videoId" value="<?= $video['videoId'] ?>" />
<input type="submit" value="Save" name="save" />
</form>
另外，如果您打算将这些数据保存到数据库中，请务必对数据调用html_entity_decode在将表单保存到数据库之前由表单发送。
Also if you are going to be saving this data into a database be sure to call html_entity_decode on the data being sent by the form before saving it to the database.
