Probably very easy to do, but for some reason...

Hi,

For some reason, my brain has gone to mush on a couple of things. Any help would be appreciated.

I have an array and a field passed into a function (call it $v) which is a string composed of comma sep values.

foo = array("one"=>1, "two", "three", "four", "five");
$ex = explode("," $v);
$newtext = "";
foreach ($ex as $e)
{
if ($e != "0")
$newtext .= " : " . $foo[$e];
}

The problem is that $e here is not being interpreted how I'd expect (I'd assume it to be a number). Do I need to cast $e as an int or is there something I'm missing?

A related problem comes from an sql query.

mysql_fetch_rows returns an array (bar). I pass this to another function. Next I try to iterate through.

The array appears to be a 2D array.

for ($m = 0; $m < count($bar); $m++)
{
for ($i = 0; $i < sizeof($bar[0]); $i++)
{
echo $bar['0']['3']; // works fine
echo $bar['0'][$i]; // doesn't work - same reason as above I'd imagine
}
}

Probably a really simple answer, but one I can't figure out. Help!!!!

TTFN

Paul
