Hey guys,
for a website, I am making an array:

PHP Code:

<?php
$title="Lists";
include("./header.php");
print "These are our lists;";
$lists= array(
    array("log"=>"blah", "foo"),
    array("list"=>"fa", "blah")
    );
foreach($lists as $val)
    {
    foreach($val as $key=>$fin_key)
        {
        print "<br />$key:<br />$fin_key<br />";
        }
    print "<br />";
    }


include("./footer.php");
?>

When I try this, I get this:



Lists

These are our lists;
log:
blah

0:
foo


list:
fa

0:
blah

I was wondering, why do I get "0:" in there?

Ilya

EDIT: I know that using the foreach is more C style than PHP...O well!

devel = foo and blah

The code does what you tell it to do, displayes every item in your list, you have a first item, with identifyer "log->blah" that holds value "foo" in the foreach it just tels you that the identifyer log is reffering to the blah, and that the first item (0) is holding the value foo.

It is _not_ C style, it is a derived feature from the C shell where foreach is buildin as a special command. php programmers just thought it would be a useful command in the php language aswell.
If anything I would say foreach orriginates from perl (http://www-106.ibm.com/developerwork...ry/l-p560.html)
