Why does ksort() return 1 instead of the sorted array? [duplicate]

Question

php: alphabetically sort multi-dimensional array by its key?

I'm trying to do the exact same thing as the guy in the thread above me. But my ksort($array) seems to return a number 1. What am I doing wrong?

Answer 1

Have a look at the manual:

bool ksort ( array &$array [, int $sort_flags = SORT_REGULAR ] )

You see, ksort returns a boolean value, and directly works on the given array (note the reference sign&). So what you're probably doing is assigning the return value of ksort, like:

$array = ksort($array);

instead of, just:

ksort($array);
