Definition and usage

max() Returns the maximum value.

Syntax

max(x,y)

Parameters

x Required. A number.

y Required. A number.

Description

max() returns the largest value in the parameter.

If there is only one parameter and it is an array, max() returns the largest value in the array. If the first argument is an integer, string, or float, at least two arguments are required and max() returns the largest of these values. An infinite number of values can be compared.

Tips and Notes

Note: PHP will treat non-numeric strings as 0, but will still return a string if it is the largest numerical value. If multiple arguments evaluate to 0 and are the maximum value, max() returns the numeric 0 among them, or the alphabetically largest string if there are no numeric 0s in the arguments.

Example

In this example, we will use max() to return the maximum of two specified numbers:
