don*_*aur 5 php xml jquery wsdl jsonp
我有一个API调用.该调用返回XML,我将XML转换为数组,然后使用json_encode在jsonp调用中发回响应.我正在做的是工作,但API不允许我按状态过滤,按开始和结束时间过滤,并确保房间可用.
几个jsponp调用让它变得疯狂.再一次,我所拥有的是工作,但我需要找到一种方法来再次使用我的结果过滤.我已经返回了正确的状态和正确的日期,但我仍然需要过滤掉时间.如果时间目前是上午10点29分,我不想显示从上午10点半开始预订的房间,因为直到上午10点半才开始预订.因此,如果我当前的时间是上午10:29,我需要过滤我的数组中的事件,并且只显示具有当前时间的开始和结束时间的事件.
从上午10点到11点的预订应该留在我的阵列中,但是从下午2-4点开始的预订不应该出现在我的阵列中.正如我所说,数组首先是一个返回的XML文档,然后是一个数组,然后是JSON,所以在技术上我可以使用任何工作来过滤.PHP以XML格式过滤,PHP过滤数组.甚至Javascript也可以通过我的ajax调用来准备PHP文件.
在我将其转换为JSON并返回之前,这是我的数组.我过滤的时间应该是TimeEventStart和TimeEventEnd.我可以使用当前的Javascript时间或PHP日期函数时间.我可以过滤数组或使用类似XMLPath的东西进行过滤.不确定什么是最有效的,最好的.

我的数组是从XML中的SOAP调用返回的.我正在获取XML并使用
$sxml = simplexml_load_string($xml)
然后我使用一个名为xmlToArray的函数将它放入发布的数组中.
$axml = xmlToArray($sxml);
在转换为Array然后转换为JSON之前,这是XML.

您可以使用Xpath过滤XML.Xpath 1.0无法比较字符串,但您也可以注册php函数.
所以用PHP编写条件:
function isBetween($current, $min, $max) {
$current = strtotime($current.'Z');
$min = strtotime($min.'Z');
$max = strtotime($max.'Z');
return $current >= $min && $current <= $max;
}
创建DOM文档并加载XML.创建Xpath实例注册PHP命名空间和函数.
$dom = new DOMDocument();
$dom->loadXml($xml);
$xpath = new DOMXpath($dom);
$xpath->registerNamespace("php", "http://php.net/xpath");
$xpath->registerPhpFunctions('isBetween');
定义使用该函数过滤Data元素节点的Xpath表达式:
// use gmtime() for current time
$now = strtotime('2014-05-13T14:00:00Z');
$expression = sprintf(
'/Bookings/Data[
php:function("isBetween", "%s", string(GMTStartTime), string(GMTEndTime))
]',
gmdate('Y-m-d\\TH:i:s', $now)
);
使用Xpath表达式获取Data元素节点:
$result = [];
foreach($xpath->evaluate($expression) as $dataNode) {
$record = [];
// convert the matching data into a record array
foreach ($xpath->evaluate('*', $dataNode) as $childNode) {
$record[$childNode->localName] = $childNode->nodeValue;
}
$result[] = $record;
}
var_dump($result);
好的，所以我写了一些 PHP 函数，来过滤出您需要的内容。
要比较 php 中的日期，最简单的方法是将它们转换为 Unix 时间。这就是第一个函数的作用。Unix 时间是自 1970 年 1 月 1 日以来经过的时间（以秒为单位）。转换它们的优点是您可以简单地使用 < 和 > 运算符来比较两个时间。
下一个函数 (nowBetween) 检查当前时间是否在通过 ($start 和 $end) 给出的两个时间之间。
然后我获取了 JSON 字符串（因为当我写这篇文章时我们并没有真正看到 XML 源）并将其转换为 PHP 数组。我们可以确定它是数组，因为json_decode中的第二个参数设置为 true。
最后但并非最不重要的一点是，我循环遍历 JSON 内容的“数据”部分中的所有预订，读取 GMTStart 和 GMTEnd 时间，并使用我们的函数检查当前时间是否在它们之间。如果不是这样，那么我从 $bookings 数组中删除预订。
结果仅是具有正确停留时间的预订。我的输出现在是空的，但那是因为您的预订日期是从 2014 年 5 月 9 日开始...当我调整它的工作时间时。
我希望这个答案适合您的需求。
function convertDateTime($datetime) {
//FORMAT IS date("YYYY-MM-DDThh:mm:ss")
$datetime = str_replace("T"," ",$datetime);
return date("U",strtotime($datetime));
}
function nowBetween($start,$end) {
$now = gmdate("U");
$start = convertDateTime($start);
$end = convertDateTime($end);
if ($start <= $now && $end > $now)
{
return true;
}
else
{
return false;
}
}
