[FX.php List] php 5 problems: I have tried to copy my existing scripts to php5 enabled servers

[Bob Patin]

I've always tested to make sure that not only is there a session  
variable by that name, but also that it's not empty, by using

if(strlen($_SESSION['myvar'])>0)

Probably an easier way, but it works fine for me so that's how I've  
been doing it...

I used to use isset, but sometimes I found that a variable was there,  
but there was nothing in it...
