My solution to get the higher key is as follows:
max(array_keys($values['Users']));
Something like this should do the trick
function array_max_key($array) {
$max_key = -1;
$max_val = -1;
foreach ($array as $key => $value) {
if ($value > $max_val) {
$max_key = $key;
$max_val = $value;
}
}
return $max_key;
}
Other answers may have shorter code but this one should be the most efficient and is easy to understand.
/**
* Get key of the max value
*
* @var array $array
* @return mixed
*/
function array_key_max_value($array)
{
$max = null;
$result = null;
foreach ($array as $key => $value) {
if ($max === null || $value > $max) {
$result = $key;
$max = $value;
}
}
return $result;
}
$newarr=arsort($arr);
$max_key=array_shift(array_keys($new_arr));
Function taken from http://www.php.net/manual/en/function.max.php
function max_key($array) {
foreach ($array as $key => $val) {
if ($val == max($array)) return $key;
}
}
$arr = array (
'11' => 14,
'10' => 9,
'12' => 7,
'13' => 7,
'14' => 4,
'15' => 6
);
die(var_dump(max_key($arr)));
Works like a charm
I know it's already answered but here is a solution I find more elegant:
arsort($array);
reset($array);
echo key($array);
and voila!
<?php
$array = array(11 => 14,
10 => 9,
12 => 7,
13 => 7,
14 => 4,
15 => 6);
echo array_search(max($array), $array);
?>
array_search() return values:
Returns the key for needle if it is found in the array, FALSE otherwise.
If needle is found in haystack more than once, the first matching key is returned. To return the keys for all matching values, use array_keys() with the optional search_value parameter instead.
