Answer Posted / vineet kumar saini
1.include() includes a file in memory no matter if it has
already been loaded
2.include_once() includes a file in memory only if it has
not been loaded already
3.require() includes a file in memory no matter if it has
already been loaded. if the file cannot be loaded, the
script is aborted
4.require_once() does the same as require(), but only if the
file hasn't been included yet. if the file's already in
memory, it has no effect.
