In general php5 scripts will work on which ever php5.x version and may
even work well in php7.x too.

Running php4 scripts on php5.x will also work as long as it don't use
oop as there was a major change how objects worked between the two major
versions.

Really so with oop ? I didn't know that. I have to check it out myself to believe it.
