Are there any best practices for dividing long scripts into smaller, more manageable parts in PHP?

When dealing with long scripts in PHP, it is best practice to divide them into smaller, more manageable parts to improve readability, maintainability, and reusability. One way to achieve this is by breaking down the script into separate functions or classes based on their functionality.

// Long script before dividing into smaller parts

function longScript() {
    // Code for a long script here
}

// Dividing into smaller parts

function partOne() {
    // Code for first part of the script here
}

function partTwo() {
    // Code for second part of the script here
}

// Call the smaller parts in sequence
partOne();
partTwo();
