how to return multiple values from a function

[ivytony]

I am wondering how to return multiple values from a function, array is a good way to go?

[BlueSkyIS]

yes.

[accident]

yup

 

 

 

function test(){

return array(1, 2, 3);

}

 

 

list($val1, $val2, $val3) = test();

Or you can just assign some global variables inside the function and don't return anything.

 

<?php
function test() {
global $var1, $var2;
list($var1, $var2) = array(1, 2);
}
test();
?>

or assign a by reference function

function swap(&$a,&$b)
{
   $a~=$b;
   $b~=$a;
   $a~=$b;
}

$a1 = 15;
$a2 = 75;

swap($a1,$a2);
echo "$a1,$a2";

Or return an object:

 

<?php

function multiValues($number1, $number2) {

  $vals->average = ($number1+$number2)/2;
  $vals->max = ($number1>$number2)?$number1:$number2;
  $vals->min = ($number1<$number2)?$number1:$number2;
  return $vals;

}

$values = multiValues(5, ;

echo $values->average;
echo $values->max;
echo $values->min;


//Output:
// 6.5
// 8
// 5
?>
