New to php! Why does the browser not display php code? PHP browser

After the browser runs, there will always be blank pages, and then the source file will find no php part of the code? The code is the downloaded source code. Is there a configuration problem?

Reply to discussion (solution)

When calling the mysql_connect () function, the system prompts "undefined function ".
Then I changed php. ini to enable mysql. dll and mysqli. dll, and changed other configurations.

The php code is not visible when you view the source file. Is there no page output for the code, so a blank page appears?

This is the code. I am not very clear about it, but didn't I write echo?

Set

Should each change like this?

It still doesn't work.

Khan ??! To End

Haha, but it still doesn't work.

In php. ini, display_errors = On is used to restart the server and run it again. there is no error message.

No error message

It must be that your if condition is false, so it is not displayed.

No error message
Are you sure you are accessing this file.
If you access this file, there must be information.

Http: // 127.0.0.1/webshop/product_info.php entered in the browser

Check the source file and find no php code.
This is correct, and php code will not appear in the browser!

So why can't I run a complete case? A blank page is displayed after logon.

Can you send the complete case to you?

Paste your code, don't

Product Content page

Require ('sub _ newslist2.php '); Require ('sub _ productlist3.php');?>

Require_once ("conn/Conn_DB.php"); // contains the database link fileIf ($ _ GET ["P_ID"]! = ""){$ Pid = $ _ GET ["P_ID"]; // product ID$ Str = "select * from Product_Info where P_ID =". $ pid; // query statement$ Arr = mysql_query ($ str); // execute an SQL statement$ Result = mysql_fetch_array ($ arr); // Obtain the query result?> }?> 'Width = "250px" height = "250px"/> Market price: Member price: "> Add to shopping cart Product Details Return

This is only one of the PHP files.
