# simple array sort question.

I am trying to get the index numbers for the highest and second highest values. So 22 and 17 are the values. Index 4 and 5 are what I need. How to do this, thanks.

\$array = array(14,11,5,2,22,17);
//\$max = max(\$array);
//\$max = array_keys(\$array, max(\$array));
//\$max = arsort(\$array);
\$max = sort(\$array);
echo \$max[0] . '<br>';
echo \$max[1] . '<br>';
var_dump(\$max);

Sort functions are documented here:

I think you want rsort()

Or maybe arsort()?  What do you need the index numbers for?

I tried rsort(), but all it prints out is - 1.

// TEST DATA FROM THE POST AT EE
\$array = array(14,11,5,2,22,17);

// SORT IN HIGH-TO-LOW, KEEPING KEYS
arsort(\$array);

// GET THE KEYS
\$keys = array_keys(\$array);

// SHOW THE TWO HIGHEST
\$highest = array_slice(\$keys,0,2);
var_dump(\$highest);
