echo "MAX value position's".$arry;
?>

echo $arry. This 1 i want to show [ MAX value position's 01.]. Or someone have better way.

You can get it with a php function, but since you're working with SQL... You should know those results are returned from the database in a non-meaningful order. — JAL, Sep 26 '13 at 05:18
Order them and get the result out from SQL itself if possible — Devesh, Sep 26 '13 at 05:19
I have no idea what you're trying to do here; what's in your array and what comes out of the query? — Ja͢ck, Sep 26 '13 at 05:53
MY teacher order "You have to use SQL and put data into array, then find 'Where max value' and show that position in array. All of these must use PHP. — T2terBKK, Sep 26 '13 at 06:13
Your suggestion to get result by SQL is not match my question. But. thank for any comment. — T2terBKK, Sep 26 '13 at 06:14

<?php
$arr_numeric= array('41', '112', '25','54');

$max_position = array_search(max($arr_numeric), $arr_numeric);

echo $max_position;

?>

position start from 0.

I get it with a google search.

$maxs = array_keys($array, max($array))

Note: this way you can retrieve every key related to a given max value.

If you are interested only in one key among all simply use $maxs[0]
