u may include a single file several times by using
include() but by using include_once() its ensured tht the
specific file would be included only once no matter how
many times u wrote it ;)

Answer / ankit
By Using include() function we can include a file any
number of times.But if you will face a Fatal error that is
a connect() or any function can not be redeclared then just
use include_once(), it will include that file only once,
then it doesn't matter how many times u include that
file. :)
