PHP插入文档mLab

我是mLab的新手，尝试在mLab上向我的mongodb插入相同的简单文档。首先，每当我运行代码时，我都可以使用shell（命令行）将一些文档插入到数据库中，我发现以下错误：

Fatal error: Uncaught MongoDB\Driver\Exception\ConnectionTimeoutException:
No suitable servers found (`serverSelectionTryOnce` set): [connection timeout calling ismaster on 'ds157390.mlab.com:57390'] in C:\xampp\htdocs\MongoDB\vendor\mongodb\mongodb\src\Collection.php:726 
Stack trace: #0 C:\xampp\htdocs\MongoDB\vendor\mongodb\mongodb\src\Collection.php(726): MongoDB\Driver\Manager->selectServer(Object(MongoDB\Driver\ReadPreference)) 
#1 C:\xampp\htdocs\MongoDB\azureConnect.php(46): MongoDB\Collection->insertMany(Array) #2 {main} thrown in C:\xampp\htdocs\MongoDB\vendor\mongodb\mongodb\src\Collection.php on line 726

PHP代码：

<?php

ini_set('max_execution_time', 0);

require 'vendor/autoload.php';

$seedData = array(
  array(
    'decade' => '1970s',
    'artist' => 'Debby Boone',
    'song' => 'You Light Up My Life',
    'weeksAtOne' => 10
),
array(
    'decade' => '1980s',
    'artist' => 'Olivia Newton-John',
    'song' => 'Physical',
    'weeksAtOne' => 10
),
array(
    'decade' => '1990s',
    'artist' => 'Mariah Carey',
    'song' => 'One Sweet Day',
    'weeksAtOne' => 16
),
 );

 $uname = "test";
 $pword = "test";
 $uri = "mongodb://".$uname.":".$pword."@ds157390.mlab.com:57390/data4estate";

 $conn = new MongoDB\Client($uri);

 $songs = $conn->data4estate->songs;

 $songs->insertMany($seedData);

尝试按照说明进行连接超时：


尝试将超时选项设置为连接字符串

您可以在php MongoClient上设置socketTimeoutMS，如下所示：

$uri = "mongodb://".$uname.":".$pword."@ds157390.mlab.com:57390/data4estate?connectTimeoutMS=300000";
