Re: [PHP-DB] php array max value pr. year
First create this array before you do anything:
$max = array(10=>1,
20=>1,
40=>1,
60=>1,
320=>1,
780=>1,
890=>1,
920=>1);
$year[2002] = $max;
$year[2003] = $max;
$i = 0;
while(list($a,$b)=each($v)) {
$year[$y[$i]][$v[$i]] = 0;
}
reset($year);
while(list($a,$b)=each($year)) {
while(list($c,$d)=each($b)) {
if ($d == 1) $next[$a][$c]=1;
}
}
At this point $next will be a two dimensional array IF all the V's in a
year are not used up. If they are, $next[2002] for example will be
!isset($next[2002]).
To get your $Y and $V:
reset($next);
while(list($a,$b)=each($next)) {
$leftoveryears[] = $a;
while(list($c,$d)=each($b)) {
$leftovervalues[] = $c;
}
}
Now $leftoveryears is an array of years and $leftovervalues is an array of
values.
I would highly recommend using a single multi-dimensional array instead of
blind indexing for your year to value pairs. IE:
$pairs[2002][10] = 1; // (if set)

Re: [PHP-DB] php array max value pr. year
Hi Martin, I am sure that many would love to help you, but really you must explain your problem more clearly! Can you give more details?
