[Chapter 7: Construct To Reference: Array($This, 'methodname')]

Hi Larry, thanks for your reply, that makes sense and playin g with the file made it already clear.

By the way, the book is great for grasping the basics of OOP.

[Chapter 7: Construct To Reference: Array($This, 'methodname')]

Change the sorting algorithm based on the desired sort order:

if ($this->_order == 'ascending') { uasort($list, array($this,

➝ 'ascSort')); } else {

uasort($list, array($this, ➝ 'descSort'));

}

 

The second argument to the uasort() function should be the name of the function to use for the comparison. 

Because that function—ascSort() or descSort()—is defined as a method

in this current object, you can use this construct to reference it: array($this, 'methodName').

 

In chapter 7 I don't get the construct above here in BOLD, did I miss something ?

Why not use uasort($list, 'ascSort');
