sorting in a class

[toshog]

hi all...

how do i refer to a sorting function in a class..

  function cmp ($a, $b) {
    			if ($a[0] == $b[0]) return 0;
   				 return ($a[0] < $b[0]) ? -1 : 1;
			}
//call:
usort($r, "cmp");

obviously i can not use usort($r, "$this->cmp");

thanks...

Hi!

Do it like this if you operate on an object of the class:

usort($r, array(&this, 'cmp'));

or like this if you don`t operate on an object of the class:

usort($r, array('ClassName', 'cmp'));

Look at Example 3. usort() example using a member function of an object

Sorry it was a typo in my post. The first sample should bee.

usort($r, array(&$this, 'cmp'));
