PHP Array variable Declare as alias

Question

I will declare an array just once. Value would like to call again and again as the key alias. please any one can help me? example:

I have :

<?php
$id =  $profile[0]->id;
$roll = $profile[0]->roll;
$photo = $profile[0]->photo;
$active = $profile[0]->active;
?>

I neeed :

<?php
$var as $profile[0];
$id =  $var->id;
$roll = $var->roll;
$photo = $var->photo;
$active = $var->active;
?>

It can be done with foreach () . However, I would like to work on Alias. i need any good idea..

Answer 1

foreach($profile[0] as $key => $val) {
    $$key = $val;
}

Answer 2

You could use list() construct for this purpose.

list($profile) = $profiles;
$id = $profile->id;
$roll = $profile->roll;
$photo = $profile->photo;
$active = $profile->active;

The variable $profile is equivalent to $profiles[0] . So, you could stick with this way of doing it.

Answer 3

I think you can try this

    <?php
    // this line you can try
    $var = array();

    // your code
    $var = $profile[0];
    $id =  $var->id;
    $roll = $var->roll;
    $photo = $var->photo;
    $active = $var->active;
    ?>

I'm not 100% sure of what you're looking for but I feel you're after references , more specifically to assign by reference :

$profile = array(
    0 => (object)array(
        'id' => '314',
        'roll' => 'XYZ',
        'photo' => 'foo.jpg',
        'active' => true,
    ),
);

$var = &$profile[0];

$id =  $var->id;
$roll = $var->roll;
$photo = $var->photo;
$active = $var->active;

var_dump($id, $roll, $photo, $active);

string(3) "314"
string(3) "XYZ"
string(7) "foo.jpg"
bool(true)

Now $var is a variable name that points to the same object that $profile[0] that you can modify it through either variables:

$var->photo = 'flowers.gif';
var_dump($profile);

array(1) {
  [0]=>
  &object(stdClass)#1 (4) {
    ["id"]=>
    string(3) "314"
    ["roll"]=>
    string(3) "XYZ"
    ["photo"]=>
    string(11) "flowers.gif"
    ["active"]=>
    bool(true)
  }
}

Of course, all this is kind of overkill if you don't actually need to alter the original array and this would suffice:

$var = $profile[0];
