include file if not already included....

[Tea_J]

hi guys

is there a function that is something like is_included() where it checks if a file has been included already previously in the script?

I have basic php files i include onto the pages, and sometimes some functions / php snippets of mine calls to include same files.. i wish to avoid this..

i know of the include_once function but dont want to use it as it slows a script down significantly...

so is there such a function? or do i need to do a work around for this?

include_once('filename.php') and require_once will serve this purpose.

Dont know why you think it will slow down your script operation.

it is quite a known fact..

here's even a routine to battle this..
