min
(PHP 3, PHP 4 )
min -- Find lowest value
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.
Note: PHP will evaluate a non-numeric string as 0, but
still return the string if it's seen as the numerically
lowest value. If multiple arguments evaluate to 0, min()
will use the first one it sees (the leftmost value).
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
?>
