PHP max( ) Function

The max() function of PHP is used to find the numerically maximum value in an array or the numerically maximum value of several specified values. The max() function can take an array or several numbers as an argument and return the numerically maximum value among the passed parameters. The return type is not fixed, it can be an integer value or a float value based on input.

Syntax:

max(array_values)  

or

max(value1, value2, ...)

Parameters: This function accepts two different types of arguments which are explained below:

1. array_values : It specifies an array containing the values.
2. value1, value2, … : It specifies two or more than two values to be compared.

Return Value: The max() function returns the numerically maximum value.

Examples:

Input : max(12, 4, 62, 97, 26)
Output : 97

Input : max(array(28, 36, 87, 12))
Output : 87

Below programs illustrate the working of max() in PHP:

Program 1:

<?php

echo (max(12, 4, 62, 97, 26));

?>

Output:

97

Program 2:

<?php

echo (max(array(28, 36, 87, 12)). "<br>");

?>

Output:

87
