You are redeclaring a function.  Most likely it's being included twice 
via an include file, this cannot be done.  Essentially, this is 
happening :
    function foo()
    {
        print 'foo';
    }
    function foo()
    {
        print 'foo';
    }
The second declaration of foo() will provide such an error.  Have a 
look around the code and locate the problem.  Consider putting the 
functions in one include, such as functions.php and include it.  Once.
A somewhat new function (4.0.2+) is called include_once , it can be 
read about here :
    http://www.php.net/manual/en/function.include-once.php
It's also an option but ideally, the code structure will be optimized 
as opposed to relying on the _once functions.
Alternatively, you could be trying to declare a function that already 
exists in php.
For example I was trying to define a mysql_escape_string function - but 
one was included in v4.0.3 !
