What are the implications of not having function overloading in PHP on code organization and maintainability?

Without function overloading in PHP, developers may need to create multiple functions with different names to achieve similar functionality for different parameter types. This can lead to code duplication, reduced readability, and increased maintenance overhead. To address this issue, developers can use conditional statements within a single function to handle different parameter types and behaviors. 

function calculate($a, $b, $operation) {
    if ($operation === 'add') {
        return $a + $b;
    } elseif ($operation === 'subtract') {
        return $a - $b;
    } elseif ($operation === 'multiply') {
        return $a * $b;
    } elseif ($operation === 'divide') {
        if ($b != 0) {
            return $a / $b;
        } else {
            return "Cannot divide by zero";
        }
    } else {
        return "Invalid operation";
    }
}

echo calculate(5, 3, 'add'); // Output: 8
echo calculate(10, 4, 'multiply'); // Output: 40
echo calculate(8, 2, 'divide'); // Output: 4
