Split an array into multiple arrays

Hi,

I have below an array I want to split in three separate arrays. One array contains the username, second array contains Firstname and the thrid array contains Lastname.

How can I achieve that?

Array ( [0] => Array ( [username] => admin [firstname] => Portal [lastname] => Administrator ) [1] => Array ( [username] => vipin [firstname] => Vipin [lastname] => Kumar ) )

Try this

/* Your array */
$arr = array(
  array(
    "username"=>"admin",
    "firstname"=>"Portal",
    "lastname"=>"Administrator"),
  array(
    "username"=>"vipin",
    "firstname"=>"Vipin",
    "lastname"=>"Kumar"));

/* New arrays */
$usernames = array();
$firstnames = array();
$lastnames = array();
foreach($arr as $user){  
  $usernames[] = $user["username"];
  $firstnames[] = $user["firstname"];
  $lastnames[] = $user["lastname"];
}

Or with this code for (somewhat) better performance:

$usernameArray = array();
$firstnameArray = array();
$lastnameArray = array();

// assume that your current array is named $currentArray
for ($i = 0, $j = count($currentArray); $i < $j; $i++){
  $usernameArray[] = $currentArray[$i]["username"];
  $firstnameArray[] = $currentArray[$i]["firstname"];
  $lastnameArray[] = $currentArray[$i]["lastname"];
}
// now you have them in separate array
