PHP扩展

PHP5.2、PHP5.3，线程、非线程，IIS、Apache综合下载地址：

http://pan.baidu.com/s/1sjrW6z7

下载相对应的php扩展文件php_mongo.dll，拷入php扩展文件夹里/php/ext，修改php.ini文件，新增下列行：

extension=php_mongo.dll

PHP操作

连接数据库

<span>$conn</span> = <span>new</span> Mongo("mongodb://localhost:27017//admin:admin");

로그인 후 복사

选择数据库和集合

<span>//</span><span>选择数据库blog,如果没有，则创建</span>

<span>$db</span> = <span>$conn</span>-><span>yyd;

</span><span>//</span><span>也可以写成：$db = $conn->selectDB('yyd');


//制定结果集（集合：yyd_test）</span>
<span>$collection</span> = <span>$db</span>-><span>yyd_test;

</span><span>//</span><span>也可以写成：$collection = $db->selectCollection('yyd_test');
//var_dump($collection);</span>

로그인 후 복사

新增数据

<span>$post</span> = <span>array</span>('name' => '22', 'sex' => '32'<span>);

</span><span>$flag</span>=(<span>$collection</span>->insert(<span>$post</span><span>));
</span><span>var_dump</span>(<span>$flag</span>);

로그인 후 복사

查找数据

<span>$arr</span>=<span>array</span><span>();
</span><span>$cursor</span> = <span>$collection</span>->find(<span>$arr</span><span>);
</span><span>foreach</span>(<span>$cursor</span> <span>as</span> <span>$key</span> => <span>$value</span><span>){
    </span><span>echo</span> "<pre class="brush:php;toolbar:false">"<span>;</span>
    <span>echo</span> <span>$value</span>['_id'<span>];
    </span><span>echo</span> '<br>name:'<span>;
    </span><span>echo</span> <span>$value</span>['name'<span>];
    </span><span>echo</span> "<br>sex:"<span>;
    </span><span>echo</span> <span>$value</span>['sex'<span>];
    </span><span>echo</span> "

"; }

条件查找

<span>$arr</span>=<span>array</span>("name"=>"22"<span>);
</span><span>$cursor</span> = <span>$collection</span>->find(<span>$arr</span>);

修改数据

PHP实现对MongoDB的基础操作

<span>$newdata</span> = <span>array</span>('$set' => <span>array</span>("email" => "test@test.com"<span>));
</span><span>$collection</span>->update(<span>array</span>("name" => "22"), <span>$newdata</span><span>);
</span><span>var_dump</span>(<span>$collection</span><span>);

</span><span>$arr</span>=<span>array</span>("name"=>"22"<span>);
</span><span>$cursor</span> = <span>$collection</span>->find(<span>$arr</span><span>);
</span><span>foreach</span>(<span>$cursor</span> <span>as</span> <span>$key</span> => <span>$value</span><span>){
    </span><span>echo</span> "<pre class="brush:php;toolbar:false">"<span>;</span>

로그인 후 복사

    <span>echo</span> <span>$value</span>['_id'<span>];
    </span><span>echo</span> '<br>name:'<span>;
    </span><span>echo</span> <span>$value</span>['name'<span>];
    </span><span>echo</span> "<br>sex:"<span>;
    </span><span>echo</span> <span>$value</span>['sex'<span>];

删除数据

<span>$arr</span>=<span>array</span>("name"=>"22"<span>);

</span><span>$collection</span>->remove(<span>$arr</span><span>);

</span><span>var_dump</span>(<span>$collection</span>);

其它常用操作

<span>//</span><span>关闭连接</span>

<span>$conn</span>-><span>close();


</span><span>//</span><span>删除一个数据库</span>

<span>$conn</span>->dropDB("yyd"<span>);


</span><span>//</span><span>列出所有可用数据库</span>

<span>$dbs</span> = <span>$conn</span>->listDBs();
