Array of Classes

[Wynder]

Let's say we have the class:

class foo
{
   var bar1;
   var bar2;

   function foo()
   {
      statement1;
      statement2;
   }
}

How would I instantiate an array of classes? So I could access them by:

echo array_name[$unique_id][$foo->bar1];

For example -- not sure if that syntax is correct. And when it's instantiated into the array, with each new elemented added, will the constructor function get executed?

Also, if I were done with an instance of a class in the array, is there a way to destroy that instance to free the memory?

[zcketcher]

$array_name[$unique_id] = new foo(); //Yes constructor gets called
//To access objects:
echo $array_name[$unique_id]->bar1;

//Or something like:
foreach($array_name as $obj) {
     echo $obj->bar1;
}

Rather than

foreach($array_name as $obj) {
     $obj->bar1 = 123;
}

..i would suggest

foreach($array_name as $key => $obj) {
     $array_name[$key]->bar1=123;
}

php4 copy those objects and if you do something to $obj-> it won't affect the copy in array.

php5 works fine with both aproaches because it copy references.
