PHP min( ) Function

The min() function of PHP is used to find the lowest value in an array, or the lowest value of several specified values. The min() function can take an array or several numbers as an argument and return the numerically minimum 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:

min(array_values)  

or

min(value1, value2, ...)

Parameters: This function accepts two different types of parameters 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 min() function returns the numerically minimum value.

Examples:

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

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

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

Program 1:

<?php

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

?>

Output:

4

Program 2:

<?php

echo (min(array(28, 36, 87, 12)));

?>

Output:

12

Important points to note :

• min() function is used to find the numerically minimum number.
• min() function can be used on two or more than two values or it can be used on an array.
• The value returned is of mixed data type.
