Use variables in functions as parameter

[Flybersite]

Hello

I want to use variables in my config.php file (which is actually an array $config)

But Zend studio keeps giving me errors about it:

Can I use them or not?

function databaseConnect($host = $config['database_host'],$username,$password,$database,$port = '3306',$socket = '')

like the first parameter

thanks

Nope. As stated in the manual: "The default value must be a constant expression, not (for example) a variable, a class member or a function call. "

A workaround is to make the default argument be null, and then test for it in the function itself. However, note that once you provide a default argument, all the following parameters must also have default arguments.
