Running the PHP file becomes a download

Question

I use an integrated php environment (xampp)
What I write is a form submission php. A separate php can be opened (entered in the browser), but once submitted, it becomes a download. Please solve.

<form method="post" action="index2.php">

Username:<input type="text" name="usernmae"/>< br>
Password: <input type="password" name="password"/><br>
Verification code: <input type="text" name="code" size="5 "/>1234<br>
Email:<input type="text" name="email"><br>
Introduction:<textarea rows="6" cols="25" name="content"></textarea><br>
<input type="submit" name="send" value="Submit">

</form>

Answer 1

Your PHP environment may not be configured properly and there is no file with .php suffix running, so the browser does not know how to process .php.

I will send you a txt text directly. Please change to a PHP integrated environment. phpstudy

Answer 2

I am using the xmapp integrated environment, which has a port number, and when it is running

Answer 3

You just right-click and open it with the browser - -

You need to use the port and protocol to run the program
