[PHP] return multiple value from function

[sanjay]

Hi List,

I am new to php programming and wanted to know if it is possible to return
multiple value from a function like cgi programs.
How can I get the following result using php.

($var1, $var2) = myfunction($a,$b);


function myfunction($c,$d)
{
   // code
// code
return ($e,$f);
}

no, it's not possible to do it that way.  If you need to return multiple
values from a function, your best bet is to return an array or some kind of
record structure.

By design, in almost all languages, functions only return a single value.

?php
function funca($a,$b)
{
$q=$a;
$w=$b;
return array($w,$q);
}

$e=123;
$r=456;

list($z,$x) = funca($e,$r);
print $z, $x\n;
?

No. But it is possible to get similar results.

a) Return an array

  $result = myfunction($a, $b);
  echo $result['e'];
  echo $result['f'];


  function myfunction($c, $d) {
do
something
$result['e'] = $this_is_e;
$result['f'] = $this_is_f;
return $result;
  }


b) Use references

  myfunction($c, $d, $e, $f);

  echo $e;
  echo $f;
 
  function myfunction($c, $d, $e, $f) {
do
something
$e = $this_is_e;
$f = $this_is_f;
  }

Best you can do is return an array and call it like this:

function myfunction($a,$b)
{
$r[0] = $a + 1;
$r[1] = $b + 1;
return $r;
}

list($c,$d) = myfunction(10,20);

Adapt to your needs.
