How can repeated function declarations in PHP code be avoided to prevent errors?

Repeated function declarations in PHP code can be avoided by checking if a function already exists before declaring it. This can be done using the `function_exists()` function. By checking if a function exists before declaring it, you can prevent errors that may occur due to redeclaring the same function. 

if (!function_exists('myFunction')) {
    function myFunction() {
        // Function implementation here
    }
}
