PHP代码可在网站上查看？

Question

Why is the below code displaying the php code from msg.php?

$flag = file('msg.php');
$content = "";
foreach ($flag as $value) {
    $content .= $value;
}
echo $content;

Is there a way I can stop it displaying the PHP code?

Answer 1

You're outputting it as text with echo and reading it with file, neither of which will execute any PHP. Your example can be replaced with:

require 'msg.php';

and everything will work properly.
