Within a class function I have defined another function for use with the
usort() function. How do I reference it?
When it's not part of a class usort($arr,"cmp") works fine but when it's
within a class function I get this error:
PHP Parse error: syntax error, unexpected T_STRING, expecting T_FUNCTION
Is it not in the scope of the class function?
you need to use an array to describe the callback function:
class Foo
{
public function cmp($a,$b)
{
// do comparison and return result
}
}
then
$foo = new Foo();
usort($arr,Array($foo,'cmp'));
I think that's right - doesn't the manual describe this sort of thing about
using callback functions that are class members?
