A function cannot be redeclared, and this will result in an error. If they
do different things, you should name them different accordingly. You can
however declare functions in mulitple places with a conditional, allthough
it's not advisable (if the function changes you have to make changes all
over). This is done by:
if(!function_exists('foo')){
function foo(){
//etc...
}
}
