Question

我试图从xml文件中获取变量并将其保存为php文件

     $xmlresponse = simplexml_load_string($dom->saveXML());
   $shipmentid = $xmlresponse->ListInboundShipmentsResult->ShipmentData->member->ShipmentId;
 echo '<br />' . $shipmentid . '<br />';


 $todaydt = new DateTime('today');
 $today3 = $todaydt->format('m-d-Y') . PHP_EOL;
 $today = rtrim($today3);
$var_str = var_export($shipmentid, true);
$var = "<?php\n\n\$shipmentid = $var_str;\n\n?>";
file_put_contents('shipmentid_' . $today . '.php', $var);

 }

但是在我的shipmentid_11-11-2016.php文件中，它正在给我

$ shipmentid = SimpleXMLElement :: __ set_state（array（ 0 =＆gt; ＆＃39; shipmentid＆＃39 ;, ））;

如何保存变量，只需

即可

$ shipmentid =＆＃39; shipmentid＆＃39;;

Answer 1

当你这样做时

 SELECT 'ASDF' c1, MAX (SUM (1)) c2
    FROM DUAL where 'ASDF' <> 'ASDF'
GROUP BY dummy

php隐式地将echo '<br />' . $shipmentid . '<br />';值转换为字符串。 $shipmentid没有这样做，所以你需要自己转换它：

var_export

接下来的事情是$var_str = strval($shipmentid);是一个字符串，并且不包含任何引号。所以，你需要自己写引号：

$var_str

SimpleXML Export＆＃34; SimpleXMLElement :: __ set_state（array（＆＃34; in Variable
