[SOLVED] function: don't require var

[ohdang888]

function test($var){

echo "you entered:". $var;

}

if you leave $var out. it says there is a missing requirement... how do i make $var optional?

function test($arg="default value")

 

The $arg="default value" is only used when the function is called like test();  Otherwise it will use whatever argument is passed to it.  $arg = 1;  test($arg); value of arg is now 1, not its default value.
