php 4.0.6 vs 4.3.4

[chriswheat]

Hello,

I have two different hosting company's and one uses 4.3.4 and the other uses version 4.0.6.

I want them to upgrade what are some of the security issues I should be aware of with 4.0.6?

I noticed that
$date = $_POST["date"];
does not work, as I am sure that other commands I am use to will not work either.

So I would like to convence them to upgrade from a security stand-point.

Might seem a wierd question, but why not just stick with the 4.3.4 one and move all the other sites over from one to another?

I would love to. However the site that is on the 4.0.6 is owned by someone else and they signed a year hosting agreement, proir to my working for them. Does any one know of major security issues with the 4.0.6 vrs 4.3.4
