because you are trying to insert identical IDs into the table. I assume ID is the primary key.

[quote author=sanfly link=topic=106006.msg423695#msg423695 date=1156808950] ... should the line in red be: ... [/quote] No, that's the point. If it were $this->$b, I would expect the code to print "AB", but I print out $this-$a twice, and for some reason the second time it turns into "B"

This code prints out "AB", and it should print out "AA". What's wrong with me? PHP 4.4.2 <?php class test { var $a=""; var $b=""; function testfunc() { $this->$a="A"; echo $this->$a; $this->$b="B"; echo $this->$a; } } $t=new test; $t->testfunc(); ?>
