Is it recommended to store PHP code in separate files rather than executing it inline?

It is recommended to store PHP code in separate files rather than executing it inline for better code organization, reusability, and maintainability. By separating code into different files, it becomes easier to manage and update specific functionalities without affecting the entire codebase. Additionally, it allows for better collaboration among developers working on different parts of the project. 

// Example of storing PHP code in a separate file

// File: functions.php
function calculateSum($num1, $num2) {
    return $num1 + $num2;
}

// File: index.php
include 'functions.php';

$sum = calculateSum(5, 3);
echo $sum; // Output: 8
