HTML未在.php文件中加载[关闭]

[UPDATED]

I have two files on my web server: test.php and test.html

Both test.php and test.html contain the same code:

<html>
<head>
<title>Hello World</title>
</head>
<body>
<p>Hello</p>
</body>
</html>

test.html prints out 'Hello' as expected but test.php is returning a blank page. What could be the problem

It looks like your PHP is misconfigured, and invoking it results in a server error. Possible reasons might be for example loading a non existing extension in your php.ini file. You need to check your apache error log to check this. If you are using PHP-FPM check if it is started and running, also check the php-fpm error log.
