Re: dynamic/multidimensional arrays in classes

$this->$arr[] should be $this->arr[] You are using a variable defined within the class - since it is a class variable you can reference it as you would anything else within the class, using '$this->' Patrick Teague wrote:

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? Patrick
