? PHP Math min() & max()

? Quick Overview

The min() and max() functions in PHP are used to determine the smallest and largest values from a group of values or an array. They are commonly used in calculations, data validation, and analytics.

? Key Concepts

• min() finds the lowest value
• max() finds the highest value
• Works with arrays or comma-separated values

? Syntax / Theory

• min(array)
• max(array)
• min(value1, value2, ...)
• max(value1, value2, ...)

? Code Example: min()

// Finding the smallest value in an array
<?php
$values = array(5, 10, 15, 20, 25);
$min_value = min($values);
echo $min_value;
?>

? Code Example: max()

// Finding the largest value in an array
<?php
$values = array(5, 10, 15, 20, 25);
$max_value = max($values);
echo $max_value;
?>

? Live Output / Explanation

The first example outputs 5 because it is the smallest value. The second example outputs 25 because it is the largest value in the array.

? Interactive Concept

You can dynamically test different values by modifying the array numbers and observing how the output changes instantly.

? Use Cases

• Finding highest scores or lowest prices
• Validating minimum or maximum limits
• Analyzing numeric datasets
