I'm having problems figuring this out. This first way gives me a 'Fatal
Error: Cannot use [] for reading in class.php on line xx'
class myClass
{
var $arr = array();
function add_something( $value )
{
$this->$arr[] = $value; // this is the line causing the error
}
}
I've also tried using count() to find out how many items are in $arr, but it
keeps saying that $r == 0... i.e.
function add_something( $value )
{
$r = count($arr);
/*
if( is_null( $r )
{
$r = 0;
}
*/
//print( $r );
$this->$arr[$r] = $value;
}
I've tried this both with & without the commented section & still $r = 0
even if you use '$class->add_something("my value");' 50 times. I'm
guessing
once this problem is solved it will work for multidimensional arrays as
well?
