"PHP and MySQL For Dynamic Web Sites." For those of you with that
book, I used Script 7.7 and replaced all the constants with my own

still dies and with the same symptoms. And since the script is
generating a form on its first pass, the header() function is not
encountered.[color=blue][color=green]

I've just installed 4.3.11 and got an illegal instruction with
session_start() as well. Unfortunately i have no solution yet. I tried
PHP 5 and then went back to 4.3.10 & still got the same - with php and
mod_php under apache. Possibly when I changed version some stuff was
left behind but the standard 4.3.11 definitely had this problem. I've
got AMD Athlon 1000 processor.
