So I got function that prints out array score which concert clinics:
array_id clinic_id score_amount
0 1 5
1 2 1
2 3 5
3 5 3
4 8 2
And i got another function that prints out array clinics id like this: This array is for listing all clinics on page,
array_id clinic_id
0 1
1 2
2 3
3 4
4 5
5 6
6 7
7 8
8 9
9 10
Now my idea is to make array of clinic_id sorted accordinally to score_amount from first array. And theen if there is no score_amount for particular clinic_id, just go with order from second array normally.
So results needs to be sorted like:
array_id clinic_id
0 1
1 3
2 5
3 8
4 2
5 4
6 6
7 7
8 9
9 10
use a custom comparator,
function cmp($a, $b)
{
if($a == $b) return 0;
\\get score returns score or -1 if no score exists
if (getscore($a) == getscore($b) {
return (index($a) < index($b)) ? -1 : 1; \\index is index of the number in second array
}
return (getscore($a) < getscore($b)) ? -1 : 1;
}
usort($a, "cmp");
You could use an associative array (clinic_id => score_amount) and use asort.
