Functions

[fesan]

Happy Saturday.

 

Can someone explain why this code returns nothing?

 

function test(){
$test = "test";
}

test();
echo $test;}

because variables are local to functions. You need

 

function test(){
   $test = "test";
   return $test;
}


echo $test();

ahh... Thanks.

And if there are allot of variables i need to get out of the function?

Do i have to return them all?

Multiple values are usually easiest to return in an array.

[50r]

function test(){

$test = "test";

$foo ="me";

$boo ="we";

return array($test,$foo,$boo);

}

$array = test();

 

then go ahead and use the valuable from the array.
