table.php (MongoDB Operation database class file)

Copy Code code as follows:

<?php
Require_once ' hrs/mongo/config.php ';
Abstract class Hrs_mongo_table
{
protected $_db = ';
protected $_name = ';
Protected $_data = Array ();
protected $c _options = Array (

protected function _setadapter ($database = ') {
if (! $database)
throw new Zend_exception (' MongoDB database name cannot be empty ');

Public Function __construct () {

Find cursor
/*
* Get Cursor Object
*/
Public function Look ($where =array (), $fields =array ()) {
if ($this->testlink ()) {
if ($fields) {
Return $where? $this->_db->find ($where, $fields): $this->_db->find ()->fields ($fields);
}else{
Return $where? $this->_db->find ($where): $this->_db->find ();

}
return false;

}
protected function Testlink () {

}
}

IMPORTANT NOTE!!!
The first of these methods

Copy Code code as follows:

Find cursor
/*
* Get Cursor Object
*/
Public function Look ($where =array (), $fields =array ()) {
if ($this->testlink ()) {
if ($fields) {
Return $where? $this->_db->find ($where, $fields): $this->_db->find ()->fields ($fields);
}else{
Return $where? $this->_db->find ($where): $this->_db->find ();
}
}
return false;
}

The second method

Copy Code code as follows:

Public function Find ($where =array (), $field =array ()) {
if ($this->testlink ()) {
$this->_data = $this->_db->find ($where, $field)->sort (Array ("_id" =>-1));
}
return $this;
}

Copy Code code as follows:

/*
* Get Cursor Object
*/
Public Function getcursor () {
return $this->_data;
}

The second need is find to get the not array
Find ($where)->getcursor (); Mongocursor Object

Pay attention.
Find () returns the current object
The ToArray () method converts the current object to an array
The GetCursor () method converts the current object to the Mongocursor object (Cursor objects)
