If the first and only parameter is an array, max() returns the highest value in that array. If at least two parameters are provided, max() returns the biggest of these values.
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 highest value. If multiple arguments evaluate to
0
, max() will return a numeric
0
if given, else the alphabetical highest string
value will be returned.
<?php
echo max(1, 3, 5, 6, 7); // 7
echo max(array(2, 4, 5)); // 5
echo max(0, 'hello'); // 0
echo max('hello', 0); // hello
echo max(-1, 'hello'); // hello
// With multiple arrays, max compares from left to right
// so in our example: 2 == 2, but 4 < 5
$val = max(array(2, 4, 8), array(2, 5, 7)); // array(2, 5, 7)
// If both an array and non-array are given, the array
// is always returned as it's seen as the largest
$val = max('string', array(2, 5, 7), 42); // array(2, 5, 7)
?>
