value="<?php echo htmlspecialchars($name); ?>"

You can do it like this,
你可以这样做,
<input type="text" name="name" value="<?php echo $name;?>" />
But seen as you've taken it straight from user input, you want to sanitize it first so that nothing nasty is put into the output of your page.
但是,当您直接从用户输入中获取它时,您希望首先对其进行清理,以便不会将任何令人讨厌的内容放入您的页面输出中。
<input type="text" name="name" value="<?php echo htmlspecialchars($name);?>" />
