Foreach Loop with Nested Arrays

[TSmith]

Hey Y'all,

I haven't programmed in PHP in quite a while. Could anyone help me
with a foreach loop in a nested array? I have a function which returns
$stock (for an online pricing catalog).

$stock[0] is ( [0] =Item, [1] =Sale, ...) an array of column
headers.
$stock[1][$i] is ([Item] =SL, [Sale] =300, ...) an array of
column headers to value for item $i

What I have to print the header row for the pricing table is:
print("<TR>");
foreach ($stock[0] as $num =$val) {
print("<TH>" + $val + "</TH>");
}
print("</TR>");

I've also tried ($stock[0] as $x) print($x).

What returns is five zeroes. Not in table cells, just "<TR>00000</
TR>".

Does anyone have any ideas what I've done?

Thank you in advance,
Taylor Smith

print("<TH>" + $val + "</TH>");

This is adding $val to two strings. Rather, you need

print("<TH>" . $val . "</TH>");

Or, you can even use:

print("<TH>$val </TH>");
