What are some best practices for organizing PHP code into modules?

Organizing PHP code into modules helps improve code readability, maintainability, and reusability. One best practice is to create separate files for each module, grouping related functions and classes together. Additionally, using namespaces can help prevent naming conflicts and make it easier to organize and locate modules within a project. 

// Example of organizing PHP code into modules using namespaces

// File: MathFunctions.php
namespace MyProject\MathFunctions;

function add($a, $b) {
    return $a + $b;
}

function subtract($a, $b) {
    return $a - $b;
}

// File: StringFunctions.php
namespace MyProject\StringFunctions;

function reverse($str) {
    return strrev($str);
}
