Create and call a function in php that uses pass-by-reference to return more than one value

Create a php script called lab04.php to display some properties of several arrays of numbers. The script must: Have a function that you create such as computeStats() that takes an array for an argument and computes the following values based on the numbers in that array:

minimum value

maximum value

average value

standard deviation

Since there is more than one return value, use pass-by-reference to return them. Use this array of arrays containing test data:

$testArray = array (
    array (1,2,3,4,5,6,7,8,9),
    array (345,23,346,234,234,456,756,345,123),
    array (456,0,234,234,45,678,789,70,436,342,234,345,35),
    array (5,5,5,5,5,5,5));

A loop to call the computeStats() function for each line in the $testArray and display a row in a table with the return values from computeStats(). The table should look something like:

Test   Min  Max  Avg   Stdev
  0        3       8       5        3
  1        3       5     ....
  2  ....
  3  ....
