php - Returning 2 values from a function -

-

this question has answer here:

is possible return 2 values when calling function output values, example, have this:

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

which output 1, want chose ouput, e.g. ids($sid), still output 1.

is possible?

you can return 1 value. can use array contains other 2 values:

return array($uid, $sid);

then access values like:

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

you use associative array:

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

and accessing it:

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