min
Find lowest value
(PHP 4, PHP 5)
mixed min ( array values )mixed min ( mixed value1, mixed value2 [, mixed value3...] )
If the first and only parameter is an array, min() returns the lowest value in that array. If at least two parameters are provided, min() returns the smallest of these values.
Note:
PHP will evaluate a non-numeric string as
0 if compared to integer, but still return the string if it's seen as the
numerically lowest value. If multiple arguments evaluate to
0, min() will return the lowest
alphanumerical string value if any strings are given, else a numeric
0 is returned.
Examples
Example 1151. 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
?>
