2 Variables from a function

[Adam W]

Is it possible to return more than 1 variable from a function and if so how do I do it.

 

Thanks

no... however... if you declare a variable a global... you can use it outside...

 

function test(){
global $test;
$test='snuffalufagus';
return 'test';
}
echo test();
echo $test;

Thanks - that is a pity, I know that you can do this in python, I'll just do 2 calls to seperate functions.

ya... cuz as soon as you return a value... function ends then and there...

You could return an array.

 

<?php

  function foo() {
    $a = 'foo';
    $b = 'bar';
    return array($a,$b);
  }

  $foo = foo();
  echo $foo[0].$foo[1];

?>

You could also return an object if wanted...

 

<?php

  function foo() {
    $return->a = 'foo';
    $return->b = 'bar';
    return $return;
  }

  $foo = foo();
  echo $foo->a.$foo->b;

?>

Not like that you couldn't. You need to define the class first and its alot of overhead for no gain really.

I should note that it does work with PHP 4.x, just tested.

 

I am unsure with PHP 5, so you could be right given the right version of PHP.

 

But that does work with PHP 4.

 

Whether or not it is considered "correct" or "good" programming I guess is something else...

Sorry frost, I take that back. Learn something everyday. Just tested it on 5.2.2 and yeah.. its works.

 

I could have swarn theat would have generated a 'method called on a non object' or whatever error that is.

I used to think that too, until one day I tried it out. My life has not been the same since ^.- =)

 

But as I stated, unsure if it is good programming or not, as PHP may decide that it should throw an error one day. But as far as I know it works and there is no less efficiency or anything and it works pretty nicely
