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?
Thanks again
Patrick
