Question

我有多个XML文档，其中包含来自API的输出 - 此输出是来自我们的票务系统的支持票据。我正在尝试计算状态设置为特定状态的票证。

XML输出如下所示（尽管7个文档中有更多请求元素）。

<response uri="/api/xml/getRequestsByView">
<result>
    <status>Success</status>
    <statuscode>200</statuscode>
    <requests>
        <request>
            <form name="requestID">12345</form>
            <form name="userTimeFormat">dd MMM yyyy, HH:mm:ss</form>
            <form name="contact">Name</form>
            <form name="status">Open</form>
            <form name="statusID">1</form>
            <form name="priority">P3 Minor</form>
            <form name="supportRep"/>
            <form name="supportRepCostPerHour">0.00</form>
            <form name="createdTime">20 Jun 2017, 08:22:00</form>
            <form name="updatedTime">20 Jun 2017, 08:23:11</form>
            <form name="dueByTime"/>
            <form name="isOverDue">false</form>
            <form name="accountID"/>
            <form name="account"/>
            <form name="subject">Subject Name</form>
        </request>
        <request>
            <form name="requestID">12346</form>
            <form name="userTimeFormat">dd MMM yyyy, HH:mm:ss</form>
            <form name="contact">Contact Name</form>
            <form name="status">Open</form>
            <form name="statusID">1</form>
            <form name="priority">P3 Minor</form>
            <form name="supportRep"/>
            <form name="supportRepCostPerHour">0.00</form>
            <form name="createdTime">20 Jun 2017, 08:21:58</form>
            <form name="updatedTime">20 Jun 2017, 08:23:10</form>
            <form name="dueByTime"/>
            <form name="isOverDue">false</form>
            <form name="accountID"/>
            <form name="account"/>
            <form name="subject">Subject Name</form>
        </request>
    </requests>
</result>

到目前为止，我创建了以下函数 - 我从下面得到的输出是“1440”。它应该工作，因为当我替换count元素以回显每个匹配时，输出显示具有匹配状态的每个票证的状态 - 只是计数元素似乎不按预期运行。

function countPriority($status){
    $files = array("includes/xml-1.xml","includes/xml-2.xml","includes/xml-3.xml","includes/xml-4.xml","includes/xml-5.xml","includes/xml-6.xml","includes/xml-7.xml");
    $count = 0;
    foreach ($files as $url) {
        $xml = simplexml_load_file($url);
        foreach ($xml->result->requests->request as $request){
            if ($request->form['3'] == $status){
                $count+= count($request);
            }
        }
        return $count;
    }
}

对于PHP / Coding，我是一个完整的新手，因此非常感谢任何建议或帮助。

这里似乎有一个错误：$count+= count($request);。如果您只是想计算具有特定状态的票数，那么您只需将计数器加1，例如$count++;。相反，您正在做的是将$count的值增加每个$request中的元素数量。

另外，正如评论中所指出的，您应该将return语句移出foreach循环，否则您的方法只会循环遍历数组中的第一个文件。

所以你的方法应该是这样的：

function countPriority($status){
    $files = array("includes/xml-1.xml","includes/xml-2.xml","includes/xml-3.xml","includes/xml-4.xml","includes/xml-5.xml","includes/xml-6.xml","includes/xml-7.xml");
    $count = 0;
    foreach ($files as $url) {
        $xml = simplexml_load_file($url);
        foreach ($xml->result->requests->request as $request){
            if ($request->form['3'] == $status){
                $count++;
            }
        }
    }
    return $count;
}
