easy question functions and returning values

dc2_jspec

how do I return multiple values from a function?

ie:

function whatever()
{
$i = 1;
$p = 2;
$h = 3;
//return i, p, h
}

whatever();

echo $i;
echo $p;
echo $h;

THANKS.

return only allows one variable out. So try and make it an array if you have more than one.

Hi,

try following:

function test() {
  return array('i'=>1, 'p'=>2, 'h'=>3);
}

$t = test();
echo $t['i'];
echo $t['p'];
echo $t['h'];

Hi,

or you could do following too:

function test() {
  GLOBAL $i, $p, $h;
  $i = 1;
  $p = 2;
  $h = 3;
}

test();
echo $i;
echo $p;
echo $h;

oh, gotcha. thanks.....one more thing while we are on the subject

I always have to do the following with functions:

$my_returned_value = whatever();

echo $my_returned_value;

Can I not do this?:

whatever();

echo $my_returned_value;

-for some reason that doesn't work for me. I return values like this, is there something else I need to do to make it work:

return $my_returned_value;

Well it must be done from my knowledge. As a function must be called. And echo 'ing it is calling it. Allowing $vars to be used that were in the function
