don't know how to retrieve and compare an array

expert_21

hi, say i have a 2 dimensional array like this:

id manufacturer

1 A
2 B
3 C

Say i want to retrieve all results from manufacturer A. What function must i use? i will have to re-use the codes for a couple of times, for manufacturer B and C.

I tried array_walk, but they said it won't work on multi-dimensional array. Any advice? thank you.

foreach() ?

hi! i wrote this:

function sort_by_manufacturer($2Darray, $manufacturer){
	foreach($2Darray as $v1){
		if ($v1[manufacturer]=$manufacturer){
			$totalentries+=1;
		}
	}
	return $totalentries;
}

however, it returns this error:
Parse error: parse error, expecting `')'' in /home/mydomain/tmp/list.php on line 9

where line 9 is function sort_by....

any ideas?

1) Variables starting with numbers is a no no.

2) if ($v1[manufacturer]=$manufacturer){
...you want ==, not =

If your're gettting a parse error on the first line of that function and there's no error, look up. Chances are it's there.
