如何获取数组的最高和最低值项？

Question

In an array like this:

$array['abc'] = 10;
$array['foo'] = 90;
$array['bar'] = 0;
$array['baz'] = 50;

How can I retrieve the highest value item (90 in the above example) and the lowest value (0 in above example)?

Answer 1

http://www.php.net/manual/en/function.min.php

echo min(2, 3, 1, 6, 7);  // 1

http://www.php.net/manual/en/function.max.php

echo max(1, 3, 5, 6, 7);  // 7

Hope that helps!

Answer 2

with min() / max()

$array = array();
$array['abc'] = 10;
$array['foo'] = 90;
$array['bar'] = 0;
$array['baz'] = 50;

echo " min: ", min($array);
echo " max: ", max($array);
