I've not had to do this before, and now that I am, I've hit a bit of a
wall:
Basically, I've an array that might look like this (the number of
elements may vary, but the letter is always unique and remains a single
character):
Array(
0 => '2h'
1 => '1d'
2 => '2w'
)
And I need to sort them according to their letter. If I wasn't using
classes, I could just use usort($array, 'custom_sort') but when I do
that within my class, I'm told it can't find the function. I've tried
usort($array, $this::custom_sort) and usort($array,
$Gantt_Task::custom_sort), both of which throw up the rather frightening
unexpected double colon error (if you've ever seen one you'll know what
I'm on about!)
Does anyone know how I can do a usort within a class without resorting
to making my sorting function a global function that isn't part of the
class? I'd rather keep this tidy and everything in the class that needs
to be in it, so a random function sitting outside is something I want to
avoid if possible.
Alternatively, if anyone knows a better way than using usort I'm all
ears!
Thanks,
