Definition: The min () function returns the lowest number in a group or array. Any strings are seen as having a value of 0, and in the case that 0 is the lowest number the first case will be returned. You can also compare multiple arrays. This compares each individual array element, and whichever has a lower number first, is returned as the min. If an array is compared to a non array, the array is always seen as being the largest, and therefor never returned as the min.
Also Known As: PHP Minimum
<?php echo min(2, 4, 6, 8) ; // Returns 2 echo min (array(2, 14, 7)) ; //Returns 2 echo min(0, 'about') ; //Returns 0 echo min ('about', 0) ; // Returns about // Comparing two arrays // so in our example: 5 = 5, but 7 < 9 $x = max(array(5, 7, 12), array(5, 9, 1)) ; //Returns array(5, 7, 12) // If both an array and non-array are given, the array is always seen as the largest, and therefor not returned $x = max('about', array(2, 4, 6), 99) ; //Returns about, as it is seen as 0 ?>
