Look at this array

array (
'a' =>
array (
'b1' =>
array (
'c1' => 1,
'c2' => 2,
'c3' => 3,
),
'b2' =>
array (
'c' => 4,
),
),
)

You can convert it to

array (
'a/b1/c1' => 1,
'a/b1/c2' => 2,
'a/b1/c3' => 3,
'a/b2/c' => 4,
)

Possibly without using a complex set of instructions:
foeach, array_map (), etc.

A little bit of complexity may be needed.

:-)

I came up with:

function pathjoin_help($o, $elms, &$res) {
if(is_int($o)) {
$res[implode('/', $elms)] = $o;
} else if(is_array($o)) {
$elms[] = null;
foreach($o as $pathelm => $value) {
$elms[count($elms)-1] = $pathelm;
pathjoin_help($value, $elms, $res);
}
} else {
die("Houston we have a problem");
}
}

function pathjoin($a) {
$res = array();
pathjoin_help($a, array(), $res);
return $res;
}

You changed:

'c1' => 1

to:

'c1' => '1'

and my code required integer.

If you want the final item to be anything then you can use:

function pathjoin_help($o, $elms, &$res) {
if(is_array($o)) {
$elms[] = null;
foreach($o as $pathelm => $value) {
$elms[count($elms)-1] = $pathelm;
pathjoin_help($value, $elms, $res);
}
} else {
$res[implode('/', $elms)] = $o;
}
}
