Returning two values from a function [duplicate]

Question

Is it possible to return two values when calling a function that would output the values?

For example, I have this:

<?php     function ids($uid = 0, $sid = '')     {         $uid = 1;         $sid = md5(time());          return $uid;         return $sid;     }      echo ids(); ?> 

Which will output 1. I want to chose what to ouput, e.g. ids($sid), but it will still output 1.

Is it even possible?

Answer 1

You can only return one value. But you can use an array that itself contains the other two values:

return array($uid, $sid); 

Then you access the values like:

$ids = ids(); echo $ids[0];  // uid echo $ids[1];  // sid 

You could also use an associative array:

return array('uid' => $uid, 'sid' => $sid); 

And accessing it:

$ids = ids(); echo $ids['uid']; echo $ids['sid']; 

Answer 2

Return an array or an object if you need to return multiple values. For example:

function foo() {     return array(3, 'joe'); }  $data = foo(); $id = $data[0]; $username = $data[1];  // or: list($id, $username) = foo();
