Aw!!! This is driving me nut... I can't get it to do what I want it to
do... Also, another problem is that we're all not thinking at the same
level so I'll just dump the simple code so you all can see what I'm trying
to do...
[code]
function getVal($arr, $path)
{
$retval = null;
if (is_string($path)) $path = explode(",", $path);
if (!is_array($arr) || empty($arr) ||
!is_array($path) || empty($path)) return null;
//$path = array_map("trim", $path);
while ($c = count($path)) {
$key = array_shift($path);
if ((!is_string($key) && !is_numeric($key)) ||
!isset($arr[ $key ]) ||
($c > 1 && !is_array($arr[ $key ]))) { return null; }
$arr = $arr[ $key ];
}
return $arr;
}
$array = array();
$array['NEWSFEED']['0']['MESSAGE']['0']['COMMENT']['0']['VALUE']
=
"&nsp;Comment #1";
$array['NEWSFEED']['0']['MESSAGE']['1']['COMMENT']['0']['VALUE']
=
"Comment <span style='color:green;'>#2</span>";
for ($y=0;$y<3;$y++)
{
//Initialize or reset...
//$key = key($array);
$key = key($array.$suffix);
$suffix .= "['".$key."']";
echo getVal($array,$suffix)." ###<br>";
}
[/code]
where I want it to look like this when done...

Problem is I can't use the foreach() loop because it would include the
numeric value into the string, like <0>blah</0>... The reason for the
numeric number is to count how many time does the non-numeric key name had
appear.
Thanks..
