Php 将XML导入MySQL数据库

我不熟悉编码，试图从一个XML文件创建一个数据库，该文件是一个行业、公司名称和符号列表。我看到了一些PHP代码示例，这些代码将数据导入MySQL，如下所示：

<?php

$url ="http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.industry%20where%20id%20in%20(select%20industry.id%20from%20yahoo.finance.sectors)&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys";
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url); //getting url contents

$data = curl_exec ($ch); //execule curl request
curl_close($ch);

$xml = simplexml_load_string($data);

$con=mysql_connect("localhost", "root", ""); //connect to server
mysql_select_db("symbol_list", $con) or die(mysql_error()); //select database

foreach ($xml -> item as $row) {
    $industry = $row -> industry;
    $company = $row -> name;
    $symbol = $row -> symbol;

// perform sql query


$sql = "INSERT INTO 'symbols_xml' ('industry', 'company', 'symbol')"
    . "VALUES ('$industry', '$company', '$symbol')";

$result = mysql_query($sql);
if (!$result) {
    echo 'MySQL ERROR';
} else {

    echo 'SUCCESS';
}


                            }

?>

    #| Industry  | Company    | Symbol
    -|----------- ------------ -------
    1| Aluminium | Alcoa Inc. | AA.BA

等等

我最近刚开始学习PHP和数据库，所以如果这是一个浪费您时间的愚蠢问题，请原谅我。xD

谢谢。

实际上你离得不远

要获取属性，可以通过两种方式进行：

将其作为一个数组来访问

$node['attributeName']

使用名为attributes（）的方法，还可以执行以下操作：

$node->attributes（）->attributeName

以下是您的代码更新：

<?php

$url ="http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.industry%20where%20id%20in%20(select%20industry.id%20from%20yahoo.finance.sectors)&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys";
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url); //getting url contents

$data = curl_exec ($ch); //execule curl request
curl_close($ch);

$xml = simplexml_load_string($data);

$con=mysql_connect("localhost", "root", ""); //connect to server
mysql_select_db("symbol_list", $con) or die(mysql_error()); //select database

foreach ($xml->results->industry as $industryNode) 
{
    foreach ($industryNode->company as $companyNode) 
    {
        $industry = (string) $industryNode['name'];
        $company = (string) $companyNode['name'];
        $symbol = (string) $companyNode['symbol'];

        // perform sql query
        $sql = "INSERT INTO 'symbols_xml' ('industry', 'company', 'symbol')"
            . "VALUES ('$industry', '$company', '$symbol')";

        $result = mysql_query($sql);
        if (!$result) 
        {        
            echo 'MySQL ERROR';
        } 
        else 
        {
            echo 'SUCCESS';
        }
    }
}

results->industry as$industryNode）
{
foreach（$industryNode->companyas$companyNode）
{
$industry=（字符串）$industryNode['name']；
$company=（字符串）$companyNode['name']；
$symbol=（字符串）$companyNode['symbol']；
//执行sql查询
$sql=“插入到“符号xml”（“行业”、“公司”、“符号”）中”
"价值("工业","公司","符号");；
$result=mysql\u查询（$sql）；
如果（！$result）
{        
回显“MySQL错误”；
} 
其他的
{
呼应"成功",；
}
}
}

非常感谢！这个“节点”的东西似乎很有效，因为现在我至少从一个“if”语句中得到了一个“MySQL错误”消息。你知道mysql\u查询有什么错吗？做一个

echo$sqlecho die（mysql_error（））if（！$result）

语句，则代码>在内部。您还可以复制粘贴输出到您喜爱的mysql客户端的查询，并查看错误。太棒了，再次感谢。问题在于语法错误-不应该在$sql=“INSERT-INTO'symbols\u xml”（行业、公司、符号）中添加“around column names”，这样做的代码要简单得多。PHP将XML文件导入数据库-

            . "VALUES ('$industry', '$company', '$symbol')";

        $result = mysql_query($sql);
        if (!$result) 
        {
