may be you can design a class.
interface ISortable{
public sort();
public compare($a,$b);
}
SortableList implements ISortable {

PHP is a scripting language.
Everytime the compiler has to parse the source.
You can not except true OOP performance.
OOP behavior is okay.
If performance is the main factor, an C extension will do that.

Inefficiency for me is when it takes longer to code.
How long can this take?
Even if you go full-blown with an Interface and static methods that have to be
fleshed out in the implementations, you're still talking about an hour or so.
Quit complaining and start typing.

Sorry. Still getting a parse error on line 40:
39 usort($authors, create_function('$a,$b','
40 $a = str_replace(array('é', 'à'), array('e', 'a'), $a);

Can you have two arrays
Dunno the original question, but this obviously should be escaped...
So the correct code follows...
usort($authors, create_function('$a,$b','
$a = str_replace(array(\'é\', \'a\'), array(\'e\', \'a\'), $a);
$b = str_replace(array(\'é\', \'a\'), array(\'e\', \'a\'), $b);

It still sorts é and e separately, but without a parse error:
$first = array('à', 'é');
$second = array('a', 'e');
usort($authors, create_function('$a,$b','
this is slightly changed function of yours, written for better

No need to write your own function, it's already in PHP. :-)
What you're looking for it natsort(). It uses natural order string
comparison (which takes into account numbers instead of just using
characters like a regular search does).
There are also lots of other 'nat' functions, such as

A quite anusual problem - and I can't figure it out..
My script, using the usort-function works properly
on my local php-environment (PHP 4.0.6) but not

I've read in a documentation, that php since 4.1.0
doesn't accept zero as return-value of the compare-function.
