    ▪php操作mongo数据库的小例子      1、连接Mongo服务器   代码示例: <?php //连接localhost:27017 $conn = new Mongo(); //连接远程主机默认端口 $conn = new Mongo('test.com'); //连接远程主机22011端口 $conn = new Mongo('test.com:22011'); //MongoDB有.........

代码示例:

<?php
$link=mysql_connect()(localhost,user,pwd);
if(!$link) echo "失败!"; else echo "成功!";
mysql_close();
?>

代码示例:

<?
$link=mysql_connect('localhost','root','123456');
if($link)
{
echo "success";
}
else {
echo "fail";
}
mysql_close();
?>
 

代码示例:

ScriptAlias /php/ "c:/php/"
AddType application/x-httpd-php .php
Action application/x-httpd-php "/php/php-cgi.exe"

代码示例:

LoadModule php5_module "c:/php/sapi/php5apache2.dll"
AddType application/x-httpd-php .php

代码示例:

<?php
//连接localhost:27017
$conn = new Mongo();
//连接远程主机默认端口
$conn = new Mongo('test.com');
//连接远程主机22011端口
$conn = new Mongo('test.com:22011');
//MongoDB有用户名密码
$conn = new Mongo("mongodb://${username}:${password}@localhost");

//MongoDB有用户名密码并指定数据库blog
$conn = new Mongo("mongodb://${username}:${password}@localhost/blog");
//多个服务器
$conn = new Mongo("mongodb://localhost:27017,localhost:27018");
?>

代码示例:

<?php
//by http://www.
//选择数据库blog
$db = $conn->blog;
//制定结果集（表名：users）

$collection = $db->users;
?>

代码示例:

<?php
//新增
$user = array('name' => 'caleng', 'email' => 'admin@admin.com');
$collection->insert($user);
//修改
$newdata = array('$set' => array("email" => "test@test.com"));
$collection->update(array("name" => "caleng"), $newdata);
//删除
$collection->remove(array('name'=>'caleng'), array("justOne" => true));
//查找
$cursor = $collection->find();
var_dump($cursor);
//查找一条
$user = $collection->findOne(array('name' => 'caleng'), array('email'));
var_dump($user);
?>

代码示例:

<?php
$conn->close();
?>
