# max

(PHP 4, PHP 5)

max — Find highest value

### Description

mixed max ( array `$values` )
mixed max ( mixed `$value1` , mixed `$value2` [, mixed `$value3...` ] )

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.

> 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 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.

### Parameters

`values`

  An array containing the values.

### Return Values

max() returns the numerically highest of the parameter values.

### Examples

Example #1 Example uses of max()

`<?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)
?>`
