I'd like to check if my understanding's correct about \[code\]require_once()\[/code\]. I have a bunch of functions in file \[code\]foo.php\[/code\]. Let's say 7/8 out of them are always used, and one of them's rather rare and rather large. I have to keep this function's definition in \[code\]foo.php\[/code\]. Can you tell me if the following approach achieves anything, and if you think it's worth what it achieves.
Take out the body of the function and put it in an external file.
Redefine the original function to \[code\]require_once()\[/code\] that particular file and pass execution over to the helper function.
I understand this could save server memory on the requests where that function isn't run. What exactly am I saving though? Just the memory it takes to hold the body of the function? That would mean it would have to be a pretty big function before being worth it I guess. Also, if I'm using something like APC does it become less useful?Please correct or add to this as appropriate!Thank you very much.
