I think the problem is easier... and also the solutions doing a "for"
instead of "foreach" are not good solutions because if the array is not
index-consecutive the loop fails.
So, if you has an array with the colors as indexes and the integer value X
as the value for that position of the array, updating is very easy.
You have an array such as:
$array = array( );
$array['blue'] = 4;
$array['orange'] = 5;
$array['green'] = 6;
....
So if you want to update the key 'orange' with a new value $new_value is as
easy as:
$array['orange'] += $new_value;
As the new value is being passed as an array so as to update it, it should
be like:
$new_value = array('orange',2);
So you have to do a foreach in the $new_value array like:
foreach ($new_value as $key => $value){
if(in_array($key,$array)){
$array[$key] += $value;
}
}
I think that solution works and is the easiest way to do it.
Cheers,
Roberto

It's rather easy:
for ($i=0; $i<count($arr); $i++) {
if ($arr[$i][0] == $new_array[0]) {
$arr[$i][1] += $new_array[1];
break; // Optional - means the first "orange" found will be
// updated only
}

Small correction:
for ($i=0; $i<count($arr); $i++)
{
if ($arr[$i][0] == $new_value [0])
{
$arr[$i][1] += $new_value [1];
break; // Optional - means the first "orange" found will be
// updated only
}
}
See here:

But, I'm not sure as to why you (Brian) would want to do that anyway.

All of that is fine and dandy, but what if he can't change the structure
of the array?
