Difference Between Min and Max Function in PHP

Introduction

In this article I will explain the min and max functions in PHP. Both functions are available as math functions. I will discuss the min() function first.

The "min()" function returns the number with the lowest value.

Syntax

min($value)

Parameter	Description
$value	Returns the lowest value

Example

The following example shows how to use the min() function:

<?php

echo min(2, 3, 1, 6, 7)." ";

echo min(array(2, 4, 5))." ";

echo min(0, 'Hi..Gaye')." ";

echo min('Hi..Gaye', 0)." ";

echo min('Hi..Gaye', -1)." ";

$value = min(array(2, 4, 8), array(2, 5, 1));

$value = min('string', array(2, 5, 7), 42);

Output

The "max()" function returns the number with the highest value.

Syntax

max($value)

Parameter	Description
$value	Returns the highest value

Example

The following example shows how to use the max() function:

<?php

echo max(1, 3, 5, 6, 7)." ";

echo max(array(2, 4, 5))." ";

echo max(0, 'Hi..Dude')." ";

echo max('Hi..Dude', 0)." ";

echo max('42', 3)." ";

echo max(-1, 'Hi..Dude')." ";

$val = max(array(2, 2, 2), array(1, 1, 1, 1));

$val = max(array(2, 4, 8), array(2, 5, 7));

$val = max('string', array(2, 5, 7), 42);
