php - 显示数据库内容

问题描述

我正在尝试使用 php 显示数据库“hospitaldb”，收集“医生”内容。我在集合中有电子邮件、密码、fname、lname 字段。当我尝试显示这些字段时，我收到错误消息：

注意：未定义索引：第 40 行 C:\xampp\htdocs\phpmongodb\viewdoctor.php 中的电子邮件

注意：未定义索引：第 41 行 C:\xampp\htdocs\phpmongodb\viewdoctor.php 中的密码

注意：未定义索引：第 42 行 C:\xampp\htdocs\phpmongodb\viewdoctor.php 中的 fname

注意：未定义索引：第 43 行 C:\xampp\htdocs\phpmongodb\viewdoctor.php 中的 lname

$server = "mongodb://localhost:27017/hospitaldb";
    try{
        $connection = new MongoDB\Client($server);
        /*$hospitaldb = $connection->test;*/
        $hospitaldb = $connection->hospitaldb;
    }catch (MongoConnectionException $ConErrMsg)
    {
        echo "$ConErrMsg";
    }

    $data = "<table style='border:1px solid red;";
    $data .= "border-collapse:collapse' border='1px'>";
    $data .= "<thead>";
    $data .= "<tr>";
    $data .= "<th>First Name</th>";
    $data .= "<th>Last Name</th>";
    $data .= "<th>Email</th>";
    $data .= "<th>Password</th>";
    $data .= "</tr>";
    $data .= "</thead>";
    $data .= "<tbody>";

    try{
        $db = $connection->hospitaldb;
        $collection = $db->doctors;
        $cursor = $collection->find();

        foreach ($cursor as $document)
        {
            $data .= "<tr>";
            $data .= "<td>" . $document["email"] . "</td>";
            $data .= "<td>" . $document["password"]."</td>";
            $data .= "<td>" . $document["fname"]."</td>";
            $data .= "<td>" . $document["lname"]."</td>";
            $data .= "</tr>";

        }

    }catch (MongoException $mongoException)
    {
        echo "$mongoException";
    }

输出 ：

object(MongoDB\Model\BSONDocument)#20 (1) {
  ["storage":"ArrayObject":private]=>
  array(5) {
    ["_id"]=>
    object(MongoDB\BSON\ObjectId)#16 (1) {

解决方案

您发布的问题对我有用：

我的设置：php 7.2 线程安全从这里下载适用于 windows 的 DLL https://pecl.php.net/package/mongodb/1.5.3/windows。我把它放在 ext 文件夹中。

作曲家.json

    "require": {
        "mongodb/mongodb": "^1.4"
    }
}

从您的帖子中执行 php 代码

<?php
require_once __DIR__ . "/vendor/autoload.php";
$server = "mongodb://localhost:27017/hospitaldb";
    try{
        $connection = new MongoDB\Client($server);
        /*$hospitaldb = $connection->test;*/
        $hospitaldb = $connection->hospitaldb;
    }catch (MongoConnectionException $ConErrMsg)
    {
        echo "$ConErrMsg";
    }

    $data = "<table style='border:1px solid red;";
    $data .= "border-collapse:collapse' border='1px'>";
    $data .= "<thead>";
    $data .= "<tr>";
    $data .= "<th>First Name</th>";
    $data .= "<th>Last Name</th>";
    $data .= "<th>Email</th>";
    $data .= "<th>Password</th>";
    $data .= "</tr>";
    $data .= "</thead>";
    $data .= "<tbody>";

    try{
        $db = $connection->hospitaldb;
        $collection = $db->doctors;
        $cursor = $collection->find();

        foreach ($cursor as $document)
        {
            $data .= "<tr>";
            $data .= "<td>" . $document["first_name"] . "</td>";
            $data .= "<td>" . $document["last_name"]."</td>";
            $data .= "</tr>";

        }

    }catch (MongoException $mongoException)
    {
        echo "$mongoException";
    }

    var_dump($data);
