Basic PHP collection

I have an entry that could have several comments associated with that entry.

If I were doing this in C# I would build a collection of these comments. However, I'm unfamiliar with a way to do this in PHP.

My current thought process is to have a comment object that has a method that would build and data_array based off of IDs and then just call that object and utilize the data that way.

Is that the easiest most basic way of doing that? Or is there a better (right way) of building a collection for PHP?

My pseudo code:

class entry
var $id
var $text


class comments
var $id
var $entryId
var $text
var $data_array;

function getCollectionById(){
    while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
    $da[$i] = array('entryId'=开发者_C百科>$row["entryId"],'text'=>$text);
    }
    $this->data_array = $da;
}

The arrays can simulate collections very effectively:

$my_collection = array();

// some loop to populate your collection

$my_collection[] = new Comment(...); // adds a new object to the end of the collection

//end loop

you can loop through it with foreach

foreach($my_collection as $comment):
   print_r($comment);
endforeach;
