Re: dynamic/multidimensional arrays in classes

Thanks, that solved the problem :) I am however now having another problem inside 1 of the class functions function return_statement() { $state = $this->statement; print_r( $this->statement ); while( list($item,$arr) = each($this->statement) ) { print "Hello"; } /* while( list($item,$arr) = each($state) ) { print "Hello"; } */ } $this->statement prints out as Array { [a] => Array ( [0]=>"1", [1]=>"2", [2]=>"3", ), [b] => Array ( [0]=>"1", [1]=>"2", [2]=>"3", ) } For some reason the first while() does not print anything, but comment the first while() & let the 2nd run & it prints. What's up with this? Is this correct or am I missing something obvious again?
