min

Description

mixed min(mixed arg1, mixed arg2, mixed argn);

min() returns the numerically lowest of the parameter values.

If the first parameter is an array, min() returns the lowest value in that array. If the first parameter is an integer, string or double, you need at least two parameters and min() returns the lowest of these values. You can compare an unlimited number of values.

If one or more of the values is a double, all the values will be treated as doubles, and a double is returned. If none of the values is a double, all of them will be treated as integers, and an integer is returned.
