Cannot redeclare urlEncodeKeys() (previously declared in

This error occurs when a function named urlEncodeKeys() is declared more than once in the same program or file. To fix this, you need to ensure that the function is only declared once.

One way to do this is to check if the function has already been declared before declaring it again. You can use the function_exists() function to do this. Here is an example:

if (!function_exists('urlEncodeKeys')) {
function urlEncodeKeys() {
// function code here
}
}

This code first checks if the function urlEncodeKeys() already exists. If it does not exist, it declares the function. If it already exists, it does not declare the function again.

Alternatively, you can move the function to a separate file and include it in your main file using the include_once() or require_once() function. This ensures that the function is only declared once.

For example, you can create a file named functions.php and define the urlEncodeKeys() function in it. Then, in your main file, you can include the functions.php file using the require_once() function:

require_once('functions.php');

This will include the functions.php file only once and ensure that the urlEncodeKeys() function is only declared once as well.
