list() and each() from multi-dim. array

[Anon]

Just curious to know. This construction can be found at manual:

$arr=array("id"=>1, "txt"=>"aaa");
while (list ($key, $val) = each ($arr)) {
//code here
}

But can I use each() and list() for array:
$arr=array(
"1"=>array("id"=>1, "txt"=>"aaa"),
"2"=>array("id"=>2, "txt"=>"bbb"),
);

Of course, it is quite possible to deal these arrays without any "each()" and "list()", but still...
Thanks!

$arr=array(
"1"=>array("id"=>1, "txt"=>"aaa"),
"2"=>array("id"=>2, "txt"=>"bbb"),
);

while (list ($key, $val) = each ($arr)) {
while (list ($innerKey, $innerVal) = each ($val)) {
echo "$key -> $val -> $innerKey -> $innerVal <br>";
}
}

should work.. the $val returned is an array... i hope 😉 try...

Yes, thank you, it works. Looks like I did not think properly about this :-)

I tried it and it prints nothing.

I'm new to this whole flippin' PHP world and am currently frustrated beyond comprehension, so if I aska stupid question...just reply with a stupid answer... :}

How do I list and assign values from a SINGLE dimension array?? Everyone is talking multi-dimensional, what's wrong with single?

$good = array (1 => $radio);

that's it. $good is now an array with values from radio buttons on the page.

Array ( [1] => Array ( [1] => 2 [2] => 2 [3] => 2 ) )

that's what it looks like (will eventually have up to 100 values...)

while (list ($key, $val) = each ($good)) {
echo "$key -> $val<br>";
}

tried that code...nothing. Now, is $key and $val fictional statements? Do they need to be replaced with something??? I have asked two friends of mine about this, both PHP, Unix gurus, can't seem to get a straight answer.
