Include():by using this include()we can embed external page
in the current script multiple time,if the embeded file is
not available it returns a warning message and executes the
rest of the statements.The include_once() is same as include
() but it includes the external file only one time and
ignores the remaining all include_once statement which
contains the same file name.
