Displaying an array with its keynames

[Pjotr Wedersteers]

I have an array with string and numerical indices:
$arr ['x'][0] = 10;
$arr ['y'][1] = 90;
$arr ['d'][1] = 45;
$arr ['y'][0] = 34;

Keys are not in a sorted order and preferably it stays that way. How can I
display the results like this:
x0 : 10
y1: 90
d1: 45
y0: 34

,using a foreach loop ? I tried with array_keys () like so:
foreach ($arr as $a) {
echo array_keys($a). " $a <br>";
}

but my output is this:
Array 10
Array 90
Array 45
Array 34

Is a foreach just not possible here or do I need to use another function or
this one differently ?
Can you help ? Thanks in advance!

Hmm, a foreach inside a foreach should do it.
foreach ($arr as $key => $val) {
foreach ($val $as $k => $v) {
print "$key: $k: $v<br />";
}
}

Best regards,

It took me a while before I found your attached reply, but it works like a
charm, thanks a bunch!

copied from php manual for "foreach"

/* foreach example 4: multi-dimensional arrays */

$a[0][0] = "a";
$a[0][1] = "b";
$a[1][0] = "y";
$a[1][1] = "z";

foreach ($a as $v1) {
foreach ($v1 as $v2) {
echo "$v2\n";
}
}
