php - 循环遍历xml并将数据存储到MySQL表中

Question

XML输出如下

<?xml version="1.0" encoding="UTF-8"?>
<Country code="GR">

   <Regions>
      <Region translation="null">Athens Airport</Region>
      <Region translation="null">Athens Coast</Region>
      <Region translation="null">Athens Suburbs-Attica</Region>
      <Region translation="null">Athens</Region>
      <Region translation="null">Central Greece-Etoloakarnania</Region>
      <Region translation="null">Central Greece-Evritania</Region>
      <Region translation="null">Central Greece-Ioannina</Region>
      <Region translation="null">Central Greece-Karditsa</Region>
      <Region translation="null">Central Greece-Larissa</Region>
      <Region translation="null">Central Greece-Magnissia</Region>
   </Regions>
</Country>

每个地区都有城市，如下

<?xml version="1.0" encoding="UTF-8"?>
<Country code="GR">
   <Cities>
      <City translation="null">Acharnes</City>
      <City translation="null">Achladies</City>
      <City translation="null">Achladochori</City>
      <City translation="null">Adamas</City>
      <City translation="null">Afandou</City>
      <City translation="null">Afiartis</City>
      <City translation="null">Agali</City>
      <City translation="null">Aghia Anna</City>
      <City translation="null">Aghia Paraskevi</City>
</Cities>

我需要的是将每个地区和国家下的所有城市插入到一个表中。一个国家有多个地区，一个地区有多个城市。我尝试过的是

$regions = array("GR" => "Greece", "BR" => "Brazil", "US" => "USA");

foreach ($regions as $code => $country) {

    $url = "URL which gives an xml output"
    file_put_contents($code . '.xml', file_get_contents($url));

    $xml = simplexml_load_file($code".xml") or die("Error: Cannot create object");

    foreach ($xml->children() as $row) {
        $region = $row->Region;
    }
}

如何循环并将其保存在 mysql 中..？TIA

如果您的 .XML 输出如下所示:

<?xml version="1.0" encoding="UTF-8"?>
<Country>
    <Code></Code>
    <Regions>
        <Region>
            <Name></Name>
            <Cities>
                <City></City>
                <City></City>
                <City></City>
            </Cities>
        </Region>
        <Region>
            <Name></Name>
            <Cities>
                <City></City>
                <City></City>
                <City></City>
            </Cities>
        </Region>
    </Regions>
</Country>
<Country>
    <Code></Code>
    <Regions>
        <Region>
            <Name></Name>
            <Cities>
                <City></City>
                <City></City>
                <City></City>
            </Cities>
        </Region>
        <Region>
            <Name></Name>
            <Cities>
                <City></City>
                <City></City>
                <City></City>
            </Cities>
        </Region>
    </Regions>
</Country>

你应该在你的 php 中执行此操作:

$url = "URL which gives an xml output";
$xml = new SimpleXMLElement($url);
foreach($xml->children() as $country){
    // Query to insert the country into the countries table by $country->Code
    foreach($country->Regions as $region){
        // Query to insert the region into the regions table by $country->Code and $region->Name
        foreach($region->Cities as $city){
            // Query to insert the city into the cities table by $country->Code and $region->Name and $city->City
        }
    }
}
