PHP7 MongDB 安裝與使用

咱們使用 pecl 命令來安裝：

 /usr/local/php7/bin/pecl install mongodb

執行成功後，會輸出如下結果：

……
Build process completed successfully
Installing '/usr/local/php7/lib/php/extensions/no-debug-non-zts-20151012/mongodb.so'
install ok: channel://pecl.php.net/mongodb-1.1.7
configuration option "php_ini" is not set to php.ini location
You should add "extension=mongodb.so" to php.ini

接下來咱們打開 php.ini 文件，添加 extension=mongodb.so 配置。

能夠直接執行如下命令來添加。

echo "extension=mongodb.so" >> `/usr/local/php7/bin/php --ini | grep "Loaded Configuration" | sed -e "s|.*:\s*||"`

注意：以上執行的命令中 php7 的安裝目錄爲 /usr/local/php7/，若是你安裝在其餘目錄，須要相應修改 pecl 與 php 命令的路徑。

Mongodb 使用

PHP7 鏈接 MongoDB 語法以下：

$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");

插入數據

將 name 爲"baidu" 的數據插入到 test 數據庫的 runoob 集合中。

<?php
$bulk = new MongoDB\Driver\BulkWrite;
$document = ['_id' => new MongoDB\BSON\ObjectID, 'name' => 'baidu'];

$_id= $bulk->insert($document);

var_dump($_id);

$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");  
$writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000);
$result = $manager->executeBulkWrite('test.runoob', $bulk, $writeConcern);
?>

讀取數據

這裏咱們將三個網址數據插入到 test 數據庫的 sites 集合，並讀取迭代出來：

<?php
$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");  

// 插入數據
$bulk = new MongoDB\Driver\BulkWrite;
$bulk->insert(['x' => 1, 'name'=>'Baidu', 'url' => 'http://www.baidu.com']);
$bulk->insert(['x' => 2, 'name'=>'Google', 'url' => 'http://www.google.com']);
$bulk->insert(['x' => 3, 'name'=>'taobao', 'url' => 'http://www.taobao.com']);
$manager->executeBulkWrite('test.sites', $bulk);

$filter = ['x' => ['$gt' => 1]];
$options = [
    'projection' => ['_id' => 0],
    'sort' => ['x' => -1],
];

// 查詢數據
$query = new MongoDB\Driver\Query($filter, $options);
$cursor = $manager->executeQuery('test.sites', $query);

foreach ($cursor as $document) {
    print_r($document);
}
?>

輸出結果爲：

stdClass Object
(
    [x] => 3
    [name] => taobao
    [url] => http://www.taobao.com
)
stdClass Object
(
    [x] => 2
    [name] => Google
    [url] => http://www.google.com
)
