Have you ever encountered this problem? The connection code of my database is written in conn. php. when used, I directly include (& quot; conn. php & quot;); reference! However, I found that when I reference the php file, it will occupy a certain amount of webpage layout space. if I do not reference it, it will be okay to directly enter the connection database code! Have you ever encountered this problem? Below is my co. have you ever encountered this problem?
My database connection code is written in conn. php. when used, I directly include ("conn. php"); reference!

However, I found that when I reference the php file, it will occupy a certain amount of webpage layout space. if I do not reference it, it will be okay to directly enter the connection database code!

Have you ever encountered this problem? Below is the content in my conn. php!

@ Mysql_connect ("localhost: 3306", "root", "") or die ("mysql connection failed ");
@ Mysql_select_db ("hu0010") or die ("db connection failed ");
Mysql_query ("set names 'utf-8 '");


This is the result displayed by directly entering the code. there is no blank space!


This is the result of reference display, blank!

Obviously, there are a lot of blank spaces. what is going on?

------ Solution --------------------
May be caused by the BOM header, or conn. php may have output.
------ Solution --------------------
Check the source code to see what causes space.
