min

Description

mixed min ( number arg1, number arg2 [, number ...])

mixed min ( array numbers [, array ...])

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

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

Example 1. Example uses of min() <?php echo min(2, 3, 1, 6, 7); // 1 echo min(array(2, 4, 5)); // 2 echo min(0, 'hello'); // 0 echo min('hello', 0); // hello echo min('hello', -1); // -1 // With multiple arrays, min compares from left to right // so in our example: 2 == 2, but 4 < 5 $val = min(array(2, 4, 8), array(2, 5, 1)); // array(2, 4, 8) // If both an array and non-array are given, the array // is never returned as it's considered the largest $val = min('string', array(2, 5, 7), 42); // string ?>
