Finding the maximum and minimum values in an array

The maximum and minimum values can be found from an array numbers with max( ) and min( ), respectively:

number max(array numbers)
number min(array numbers)

If an array of integers is examined, the returned result is an integer, if an array of floats is examined, min( ) and max( ) return a float:

$var = array(10, 5, 37, 42, 1, -56);
echo max($var);  // prints 42
echo min($var);  // prints -56

Both min( ) and max( ) can also be called with a list of integer or float arguments:

number max(number arg1, number arg2, number arg3, ...)
number min(number arg1, number arg2, number arg3, ...)

Both max( ) and min( ) work with strings or arrays of strings, but the results may not always be as expected.
