php not working inside html code in wampserver

问题

Here's the thing.. I have a file named first.php containing the following code:

<html>
    <title>trial</title>
    <head>welcome</head>
    <body>
    <br>
    <?php
    echo "hello world";
    ?>
    </body>
</html>

However when I execute it, the php code is not interpreted. The short open tag also seems to be on. I'm using wampserver. what have I missed?

回答1:

<html>
  <head>    
    <title>trial</title>
  </head>
  <body>
    <?php echo "hello world"; ?>
  </body>
</html>

Try it with the title wrapped inside the head like it should be. The welcome was just floating around in no mans land, may have broken your code. Also, use a doctype tag - < !html> without the space is HTML5.

Update Add this to a blank php file in your localhost folder.

<?php
// Show all information, defaults to INFO_ALL
phpinfo();
?>

If you don't get a report back, it's a server config problem.

Also make sure your putting it in htdocs or whatever your "public" folder is.

It seems your server is misconfigured. Your apache server must recognize .php files as a php application and evaluate the code.

AddHandler application/x-httpd-php .php

See if you find the line above in your http.conf file.

回答3:

make sure you place the .php file(s) under a directory say "myfirst" under /wamp/www
make sure the wamp server is online (shows green icon)
Enable short tags click on wamp icon > PHP > PHP Settings > short open tags. Make sure it is checked.
run the code in browser as localhost/myfirst/first.php

hopefully it works

Make the changes suggested by @kcdwayne.

Now run the code from your browser, DONT doubleclick on your php file from explorer, it has to run through a browser.

回答5:

The Tag must be inside the Tag

<head> 
   <title>trial</title>
</head>
<body>
 <?php echo "hello world"; ?>
</body>
