Why do I get a fatal error "redeclaring" a function that's only declared once?

Question

(Coding PHP with MySQL)

Fatal error: Cannot redeclare logged_in() (previously declared in C:\xampp\htdocs\Project\Func\user.func.php:9) in C:\xampp\htdocs\Project\Func\user.func.php on line 9

I'm making a function to check if a user is logged in. I declare the function as logged_in() {}, but the function causes the error seen above, even though I've never declared it before.

The function didn't work when it was defined either, with an isset and a reference to MySQL code.

May you show the complete line declaring the function? – apaderno Aug 20 '11 at 10:16 — apaderno, Aug 20 '11 at 10:16

It must have been declared previously somewhere.

Maybe you are including user.func.php twice?

+1 Here's a hint to prevent such errors: prefer `include_once` over `include`! – feeela Aug 20 '11 at 11:27

If you can't work out whether you've declared it before, use this function in a separate test class. It'll identify how many times you've called the function.

If it says it's being called before, download a search program like grepWin and search your public_html folder for the file that's hosting your rogue function.
