Question

In my PHP codes, I always have this problem that I can not use include somewhere!

For e.g. I’m using MySQL to connect to my database and I made a global.php to include & connect to my database and use it for all other PHP files.

But somewhere I keep getting the error:

Fatal error: Cannot redeclare connect() (previously declared in C:\xampp\htdocs\mypm\functions\global.php:4) in C:\xampp\htdocs\mypm\functions\global.php on line 7

I can not include or use some files that uses global.php in other PHP files!

Any suggestions? Thanks

Here is the code

require ('users.php'); function get_gravatar($id) { $email = get_email($id); $s = 80; $d = 'mm'; $r = 'g'; $img = false; $atts = array();
$url = 'http://www.gravatar.com/avatar/'; $url .= md5( strtolower( trim($email) ) ); 
$url .= "?s=$s&d=$d&r=$r";
    if ( $img ) {
       $url = '<img src="' . $url . '"'; foreach ( $atts as $key => $val ) $url .= ' ' . $key . '="' . $val . '"'; $url .= ' />'; } return $url; 
    }

PHP has alternate versions of include() and require() which address this problem. Use include_once() or require_once() for files which might be included from multiple files to prevent the common file from being included in your code multiple times.
