optional parameters in functions

[eluser]InsiteFX[/eluser]
Hi,

Code:

if (empty($variable)
{
   // variable is empty no value
   dothis;
}
else
{
    // variable has a value
    dothis;
}

// Or you can do a single check like this

if ( ! empty($variable)
{
   // variable has a value
   dothis;
}

Enjoy
