Laravel 4 - Convert arrays of objects into individual objects

问题

I hope you can help me with this simple problem in converting arrays of objects to individual objects. So I can directly call their attributes.

What I mean is, I have this data listed below:

array(3) {
  [0]=>
  object(stdClass)#259 (8) {
    ["id"]=>
    int(2)
    ["author_id"]=>
    int(2)
    ["title"]=>
    string(17) "The Emperorasdasd"
    ["publisher"]=>
    string(15) "De publishing"
    ["created_at"]=>
    string(19) "2013-10-11 12:49:00"
    ["updated_at"]=>
    string(19) "2013-10-12 09:44:58"
    ["date_published"]=>
    string(10) "02-12-2013"
    ["name"]=>
    string(8) "John Doe"
  }
  [1]=>
  object(stdClass)#260 (8) {
    ["id"]=>
    int(1)
    ["author_id"]=>
    int(1)
    ["title"]=>
    string(4) "Demo"
    ["publisher"]=>
    string(10) "ooqwwoeqoe"
    ["created_at"]=>
    string(19) "2013-10-12 09:45:31"
    ["updated_at"]=>
    string(19) "2013-10-12 09:45:36"
    ["date_published"]=>
    string(10) "26-12-1993"
    ["name"]=>
    string(11) "Demo"
  }
  [2]=>
  object(stdClass)#261 (8) {
    ["id"]=>
    int(1)
    ["author_id"]=>
    int(1)
    ["title"]=>
    string(12) "Read My Mind"
    ["publisher"]=>
    string(13) "TF Publishing"
    ["created_at"]=>
    string(19) "2013-10-12 09:46:53"
    ["updated_at"]=>
    string(19) "2013-10-12 09:46:53"
    ["date_published"]=>
    string(10) "30-11-2009"
    ["name"]=>
    string(11) "James Mones"
  }
}

How will I convert the 3 item array into 3 individual objects? So I can call them directly like: $books->id, not $books[0]->id ?

回答1:

Its not 100% clear what you mean, whether you want the three objects as seperate variables or you just need a way of accessing them.

A simple foreach should suffice.

foreach ( $collection as $model ) 
{
    $id = $model->id;
}

alternatively the answer supplied by Eugen would grab specific indexes to variables for you to use.

回答2:

Is this, what you mean?

$book0 =& $books[0];
$book1 =& $books[1];
$book2 =& $books[2];

echo $book0->id

回答3:

You can use

list($books1, $books2, $books3) = $arrayOfObjects;

DEMO.

So, if your $arrayOfObjects has three objects inside it then every objects will be extracted from the array and will be stored in variables supplied in the list and you can use the first object like

echo $books1->id;
echo $books2->id;
echo $books3->id;

Also, using a loop you can do it like

foreach($arrayOfObjects as $books) {
    echo $books->id;
}
