What are the best practices for implementing PHP scripts quickly without wasting time?

When implementing PHP scripts quickly, it's important to follow best practices to avoid wasting time. One way to do this is to organize your code into separate files for better readability and maintainability. Additionally, using functions and classes can help streamline your code and make it easier to reuse. Finally, make sure to test your scripts thoroughly to catch any errors early on.

// Example of organizing code into separate files
// index.php
include 'functions.php';

// functions.php
function greet() {
    echo 'Hello, World!';
}

// Using functions to streamline code
function add($num1, $num2) {
    return $num1 + $num2;
}

// Testing scripts
echo add(2, 3); // Output: 5
