php echo html 标记，因此它是可见的(不解释为代码)
我目前正在尝试从包含 html 样式标签的变量中回显文本值.<...>
I am currently trying to echo a text value from a variable which contains html-style tags. <...>
$string = "variable_name";
$tag_str = "<".$string.">";
echo $tag_str;
目前这个回声没有什么，因为它认为它是 html 代码.我将如何将 <variable_name> 回显到页面，使其可见而不被浏览器解释为代码?
currently this echo's as nothing as it believes it is html code. How would I go about echoing <variable_name> to the page so it is viewable and not interpreted as code by the browser?
推荐答案
你必须对你的输出进行 html 编码
You'll have to html encode your output
$string = "variable_name";
$tag_str = "<".$string.">";
echo htmlspecialchars($tag_str);
