how to get top 3 values in php array and their index

Question

I want to get the highest value, the second highest value and the third highest value

For example, I have an array like:

$n = array(100,90,150,200,199,

Answer 1

You can achieve it by using arsort() and array_keys() functions:

• arsort() sorts an array in reverse order and maintains index association
• array_keys() returns all the keys or a subset of the keys of an array

Process array:

$n = array(100,90,150,200,199,155,15,186);
arsort($n);
$keys = array_keys($n);

Get top 3 values:

echo $n[$keys[0]];
echo $n[$keys[1]];
echo $n[$keys[2]];
