What steps can be taken to avoid errors when working with PHP functions in scripts?

To avoid errors when working with PHP functions in scripts, it is important to ensure that the function exists before calling it. This can be done using the `function_exists()` function to check if the function is defined. Additionally, it is recommended to handle any potential errors or exceptions that may occur when calling the function. 

if (function_exists('my_function')) {
    // Call the function
    my_function();
} else {
    // Handle the case when the function is not defined
    echo 'Function does not exist';
}
