“Fatal error: Cannot redeclare ”

Question

I have a function(this is exactly how it appears, from the top of my file):

Answer 1

Since the code you've provided does not explicitly include anything, either it is being incldued twice, or (if the script is the entry point for the code) there must be a auto-prepend set up in the webserver config / php.ini or alternatively you've got a really obscure extension loaded which defines the function.

Answer 2

I want to add my 2 cent experience that might be helpful for many of you.

If you declare a function inside a loop (for, foreach, while), you will face this error message.

Answer 3

I'd recommend using get_included_files - as Pascal says you're either looking at the wrong file somehow or this function is already defined in a file that's been included.

require_once is also useful if the file you're attempting to include is essential.

Answer 4

or you can't create function in loop

• such as

  for($i=1; $i<5; $i++) { function foo() { echo 'something'; } }

foo();
//It will show error regarding redeclaration

Answer 5

You're probably including the file functions.php more than once.

Answer 6

you can check first if name of your function isn`t exists or not before you write function By

  if (!function_exists('generate_salt'))
{
    function generate_salt()
    {
    ........
    }
}

OR you can change name of function to another name
