Abstract class Phalcon\Mvc\Model\Resultset

implements Phalcon\Mvc\Model\ResultsetInterface, Iterator, Traversable, SeekableIterator, Countable, ArrayAccess, Serializable

This component allows to Phalcon\Mvc\Model returns large resulsets with the minimum memory consumption Resulsets can be traversed using a standard foreach or a while statement. If a resultset is serialized it will dump all the rows into a big array. Then unserialize will retrieve the rows as they were before serializing.

<?php

 //Using a standard foreach
 $robots = Robots::find(array("type='virtual'", "order" => "name"));
 foreach ($robots as $robot) {
  echo $robot->name, "\n";
 }

 //Using a while
 $robots = Robots::find(array("type='virtual'", "order" => "name"));
 $robots->rewind();
 while ($robots->valid()) {
  $robot = $robots->current();
  echo $robot->name, "\n";
  $robots->next();
 }

Methods

public next ()

Moves cursor to next row in the resultset

public int key ()

Gets pointer number of active row in the resultset

public rewind ()

Rewinds resultset to its beginning

public seek (int $position)

Changes internal pointer to a specific position in the resultset

public int count ()

Counts how many rows are in the resultset

public boolean offsetExists (int $index)

Checks whether offset exists in the resultset

public Phalcon\Mvc\ModelInterface offsetGet (int $index)

Gets row in a specific position of the resultset

public offsetSet (int $index, Phalcon\Mvc\ModelInterface $value)

Resultsets cannot be changed. It has only been implemented to meet the definition of the ArrayAccess interface

public offsetUnset (int $offset)

Resultsets cannot be changed. It has only been implemented to meet the definition of the ArrayAccess interface

public int getType ()

Returns the internal type of data retrieval that the resultset is using

public Phalcon\Mvc\ModelInterface getFirst ()

Get first row in the resultset

public Phalcon\Mvc\ModelInterface getLast ()

Get last row in the resultset

public Phalcon\Mvc\Model\Resultset setIsFresh (boolean $isFresh)

Set if the resultset is fresh or an old one cached

public boolean isFresh ()

Tell if the resultset if fresh or an old one cached

public Phalcon\Mvc\Model\Resultset setHydrateMode (int $hydrateMode)

Sets the hydration mode in the resultset

public int getHydrateMode ()

Returns the current hydration mode

public Phalcon\Cache\BackendInterface getCache ()

Returns the associated cache for the resultset

public Phalcon\Mvc\ModelInterface current ()

Returns current row in the resultset

public Phalcon\Mvc\Model\MessageInterface [] getMessages ()

Returns the error messages produced by a batch operation

public boolean delete ([Closure $conditionCallback])

Deletes every record in the resultset

public Phalcon\Mvc\Model [] filter (callback $filter)

Filters a resultset returning only those the developer requires

<?php

 $filtered = $robots->filter(function($robot){
    if ($robot->id < 3) {
            return $robot;
    }
});

abstract public array toArray () inherited from Phalcon\Mvc\Model\ResultsetInterface

Returns a complete resultset as an array, if the resultset has a big number of rows it could consume more memory than currently it does.
