Array question

[pedroz]

I have the following array:

$string = ('10','21','22','30','41','42','43');

I need to count the number of values which start with 1, 2, 3, 4

to get this...
1: result 1
2: result 2
3: result 1
4: result 3

huh?

what does result1 mean? and i assume the 1 2 3 4 is that you want them to be in order right(lowest to highest)?

here is one way of doing it:

$result=array();
while(list($k,$v)=each($string))
{
$result[substr($v,0,1)]++;
}
print_r($result);
