使用带有foreach的sql将xml插入sql？

Question

首先，我有一个来自 unibet.com 的 xml 提要，如下所示：

    <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<betOfferResponse>
    <events>
        <name>Red Star Belgrade - CSKA Moscow</name>
        <homeName>Red Star Belgrade</homeName>
        <awayName>CSKA Moscow</awayName>
        <start>2018-02-13T17:00Z</start>
        <group>Europa League</group>
        <type>ET_MATCH</type>
        <sport>FOOTBALL</sport>
        <state>NOT_STARTED</state>
        <liveBetOffers>true</liveBetOffers>
        <openForLiveBetting>false</openForLiveBetting>
        <id>1004394826</id>
        <groupId>2000051195</groupId>
        <path>
            <id>1000093190</id>
            <name>Football</name>
            <englishName>Football</englishName>
        </path>
        <path>
            <id>2000051195</id>
            <name>Europa League</name>
            <englishName>Europa League</englishName>
        </path>
    </events>
    <events>
        <name>FC Astana - Sporting Lisbon</name>
        <homeName>FC Astana</homeName>
        <awayName>Sporting Lisbon</awayName>
        <start>2018-02-15T16:00Z</start>
        <group>Europa League</group>
        <type>ET_MATCH</type>
        <sport>FOOTBALL</sport>
        <state>NOT_STARTED</state>
        <liveBetOffers>true</liveBetOffers>
        <openForLiveBetting>false</openForLiveBetting>
        <id>1004394832</id>
        <groupId>2000051195</groupId>
        <path>
            <id>1000093190</id>
            <name>Football</name>
            <englishName>Football</englishName>
        </path>
        <path>
            <id>2000051195</id>
            <name>Europa League</name>
            <englishName>Europa League</englishName>
        </path>
    </events>

但是当我使用我的脚本读取 xml 数据并将其放入我的数据库时，它不起作用，因为这些：

 <betOfferResponse>

但是当我创建自己的 xml 时只使用下面的数据，它就可以工作。但它不能循环文件并获取第二个条目等等..

这是我的 php 代码：

    <?php


$xml=simplexml_load_file("test.xml") or die("Error: Cannot create object");
$connection = mysqli_connect("localhost", "root", "password", "tipstr") or die ("ERROR: Cannot connect");

/* Assumes that the number of IDs = number of customers */
$size = sizeOf($xml->id);
$i = 0; //index

/* Add each customer to the database, See how we reference it as    $xml->ENTITY[INDEX] */
while($i != $size) 
{
    print_r($xml);
    echo $xml->id[$i]; //Test

    $sql = "INSERT INTO xf_nflj_sportsbook_event (event_id, category_id, user_id, username, title, description, event_status, date_create, date_open, date_close, date_settle, date_edit, event_timezone, wagers_placed, amount_staked, amount_paidout, likes, like_users, view_count, outcome_count, comment_count, thread_id, prefix_id, last_comment_date, limit_wagers_single_outcome) VALUES ('$xml->id',2,1,'tipstr', '$xml->name', '$xml->sport', 'open', 1517755596,1517755596,1517761200,1517761200,0,'Europe/London', 0, 0,0,0,0,0,0,0,0,0,0,0)";
    mysqli_query($connection, $sql) or die ("ERROR: " .mysqli_error($connection) . " (query was $sql)");

    $i++; //increment index
}


mysqli_close($connection);

我做错了什么？如何循环/foreach 插入查询，以便它可以获取整个文件而不仅仅是第一个文件，以及如何让它从 unibet 读取 xml？

编辑： 很抱歉没有添加我成功时使用的 xml。但这里是：

我没有收到任何特殊错误，当我在 xml 中添加更多项目时，只有我写入的 php 错误。所以尝试检查控制台中的网络选项卡，但也没有。

感谢 Nigel Ren 给了我正确的公式，这是所有缺失数据的正确答案..

现在我终于可以从 unibet 的 xml 中获取数据了 :)

 <?php


$xml=simplexml_load_file("xml url") or die("Error: Cannot create object");
$connection = mysqli_connect("localhost", "root", "password", "db_name") or die ("ERROR: Cannot connect");

/* Assumes that the number of IDs = number of customers */
$size = sizeOf($xml->id);
$i = 2; //index

/* Add each customer to the database, See how we reference it as    $xml->ENTITY[INDEX] */
while($i != $size) 
{
    print_r($xml);
    echo $xml->id[$i]; //Test
    foreach($xml->events as $event) //Extract the Array Values by using Foreach Loop
    {
    $sql = "INSERT INTO xf_nflj_sportsbook_event (event_id, category_id, user_id, username, title, description, event_status, date_create, date_open, date_close, date_settle, date_edit, event_timezone, wagers_placed, amount_staked, amount_paidout, likes, like_users, view_count, outcome_count, comment_count, thread_id, prefix_id, last_comment_date, limit_wagers_single_outcome) VALUES ('$event->id',2,1,'tipstr', '$event->name', '$event->sport', 'pending', 1517755596,1517755596,1517761200,1517761200,0,'Europe/London', 0, 0,0,0,0,0,0,0,0,0,0,0)";
    mysqli_query($connection, $sql) or die ("ERROR: " .mysqli_error($connection) . " (query was $sql)");

    $i++; //increment index
    }
}


mysqli_close($connection);

您应该更改循环以使其更容易...

<?php
$xml=simplexml_load_file("xml url") or die("Error: Cannot create object");
$connection = mysqli_connect("localhost", "root", "password", "db_name") or die ("ERROR: Cannot connect");

foreach ( $xml->events as $event )  {
    $sql = "INSERT INTO xf_nflj_sportsbook_event
                (event_id, category_id, user_id, username, title,
                description, event_status, date_create, date_open,
                date_close, date_settle, date_edit, event_timezone,
                wagers_placed, amount_staked, amount_paidout, likes,
                like_users, view_count, outcome_count, comment_count, thread_id,
                prefix_id, last_comment_date, limit_wagers_single_outcome)
        VALUES ('{$event->id}',2,1,'tipstr', '{$event->name}', '{$event->sport}',
                'open',
                1517755596,1517755596,1517761200,1517761200,0,'Europe/London',
                0, 0,0,0,0,0,0,0,0,0,0,0)";
     mysqli_query($connection, $sql) or die ("ERROR: " .mysqli_error($connection) . " (query was $sql)");
}

请注意，我已更改数据嵌入字符串的方式，因为每个元素现在都称为 $event 我已将它们更改为 {$event->id} 等。

您还应该查看准备好的语句，因为您可以准备此语句一次，然后对每行数据执行多次。

这不会产生任何输出，只是将数据从文件中插入到数据库中。
