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]
fantastic function - couldn't have written it better myself. ;-)
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";
$array['NEWSFEED']['0']['MESSAGE']['1']['COMMENT']['0']['VALUE'] =
"Comment <span style='color:green;'>#2</span>";
get to grips with var_dump() ...
var_dump($array);
for ($y=0;$y<3;$y++)
{
//Initialize or reset...
//$key = key($array);
$key = key($array.$suffix);
here your doing exactly what you first asked if you could do
and were told you couldn't (not exactly like that anyhow)
($array.$suffix) will never be an array
$suffix .= "['".$key."']";
this $suffix 'path' is being created in a way that
is not compatible with getVal(). the second arg
to getVal() can either be an array where the values
are the keys to 'dig' in with or a comman delimited
string containg the key names ... e.g:
$path1 = array('key1','key2','key3');
$path2 = 'key1,key2,key3';
$path1 and $path2 will give the same result.
echo getVal($array,$suffix)." ###<br>";
getVal() will only ever return NULL
}
[/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
could you rephrase that in english?
numeric number is to count how many time does the non-numeric key name had
appear.
array_count_values() might interest you.
Thanks..
