Cannot redeclare function

Hi all,

I have a script that checks to see if the usernames and passwords users enter are correct, but the problem is in a file called common.php, a file that contains basic variable and function definitions. Here's the error I receive:

Quote:

Fatal error: Cannot redeclare errormsg() (previously declared in /usr/local/www/virtual2/66/175/22/189/html/cms/common.php:26) in /usr/local/www/virtual2/66/175/22/189/html/cms/common.php on line 26

And the code that causes the error: (Line 26 is the one that says: function errorMsg(...) Also, in the files in which this file is include()d, there aren't any function definitions in them.

PHP Code:


		
			
<?php // common.php



// Default Width of Message Tables

$deftablewidth = "70%";



// Header Background Color

$headcolor = "#000099";



// Header Text Color

$headtextcolor = "#FFFFFF";



// Row 1 Background Color

$row1back = "#CCCCFF";



// Row 2 Background Color

$row2back = "#9999FF";



// Default Font

$defaultfont = "Verdana,Arial,Helvetica";



// Default Font Size

$defaultfontsize = "2";

    </tr>

    </form>

    </table>

    <?php

    include('includes/footer.html');

    ?>

    </html>

    <?php

}

?>

Any ideas as to what could be causing this?

Thanks,

easy

change this line

function errorMsg($title, $msg) {

to this

function anothername($title, $msg) {

i think the name of your function is causing you problems

Hi Ben,

I found the error.

You see, when a page is called, a file called accesscontrol.php is included to check if the username and password of the user are correct. This file includes common.php. However, I also included common.php in the file after including accesscontrol.php.

So, to anybody who has this problem, change require(...); or include(...); to require_once(...); or include_once(...);.

Thanks for the help though, Ben!
