Setting default function parameters with variable in php

[bacardibaby]

I would like to do something like:\[code\]function func($var1 = 'Hello', $var2 = "{$var1} World") { echo $var2; }\[/code\]This is not possible!My idea is to avoid extra code lines inside my function but I don't know if that is possible.Does someone know if a similar procedure is possible in php?Thanks.
