There are at least two ways you could do this: Put the declaration of
foo() inside this if block, if( !function_exists('foo')) { .... }, so
the function is only parsed if it hasnt already been declared. Another
way is put if( defined('fufile') ) {return;} define('fufile',1); at the
top of the file foo() is declared in - it quickly exists the include'd
file when it is included a 2nd/3rd/... time.
