Question

我正在开发一个显示属性的网站。我有一个巨大的XML feed，我把它放入一个数组中。

function search_results($department = '', $post_code = '', $min_price = '', $max_price = '', $type = '', $bedrooms = '') {
    foreach($this->xml->property as $property) {
        if($property->department == $department) {
            $this->properties[] = $property; 
        }
    }
    $this->filter_results();
}

首先根据“For Sale”或“To Rent”等部门过滤XML。我想现在能够根据我通过函数传递的变量来搜索这个数组。例如：

if($this->properties->regionID == $post_code) {
    $this->properties[] = $property;
}

但这不起作用。这将在名为Results的类中。我将如何搜索阵列。我看了一下使用array_filter（）;但我无法使它工作，当我print_r它时会返回Array（）。

有谁知道如何搜索/过滤数组？

这是print_r时数组的样子：

数组（[0] =＆gt; SimpleXMLElement对象（[propertyID] =＆gt; 1 [branchID] =＆gt; 1 [clientName] =＆gt;名称[branchName] =＆gt;分支[部门] =＆gt;租赁[ referenceNumber] =＆gt; 1 [addressName] =＆gt; 4 [addressNumber] =＆gt; SimpleXMLElement对象（）[addressStreet] =＆gt;地址[address2] =＆gt; address2 [address3] =＆gt; address3 [address4] =＆gt; SimpleXMLElement Object（）[addressPostcode] =＆gt; postcode [country] =＆gt; postcode [displayAddress] =＆gt; address [propertyBedrooms] =＆gt; 1 [propertyBathrooms] =＆gt; 1 [propertyEnsuites] =＆gt; 0 [propertyReceptionRooms] = ＆gt; 1 [propertyKitchens] =＆gt; 1 [displayPropertyType] =＆gt;单位/公寓[propertyType] =＆gt; 2 [propertyStyle] =＆gt; 16 [propertyAge] =＆gt; 0 [floorArea] =＆gt; 0.00 [floorAreaUnits] =＆gt; sq ft [propertyFeature1] =＆gt;已转换的校舍[propertyFeature2] =＆gt;市中心位置[propertyFeature3] =＆gt;现代装修[propertyFeature4] =＆gt; SimpleXMLElement对象（）[propertyFeature5] =＆gt; S impleXMLElement Object（）[propertyFeature6] =＆gt; SimpleXMLElement Object（）[propertyFeature7] =＆gt; SimpleXMLElement Object（）[propertyFeature8] =＆gt; SimpleXMLElement Object（）[propertyFeature9] =＆gt; SimpleXMLElement Object（）[propertyFeature10] =＆gt; SimpleXMLElement Object（）[rent] =＆gt; 525 [rentFrequency] =＆gt; 1 [toLetPOA] =＆gt; 0 [studentProperty] =＆gt; SimpleXMLElement Object（）[availability] =＆gt; 2 [mainSummary] =＆gt;摘要。 [fullDescription] =＆gt; SimpleXMLElement Object（）[dateLastModified] =＆gt; 2014-05-02 [featuredProperty] =＆gt; 0 [regionID] =＆gt; 27 [纬度] =＆gt; SimpleXMLElement Object（）[longitude] =＆gt; SimpleXMLElement Object（）[flags] =＆gt; SimpleXMLElement Object（）[images] =＆gt; SimpleXMLElement对象（[image] =＆gt;数组（[0] =＆gt;图像[1] =＆gt;图像[2] =＆gt;图像[3] =＆gt;图像[4] =＆gt;图像）））< / p>

有谁知道我将如何搜索此查询，例如

$post_code = 43; $min_price = 300; $max_price = 500

等等。

查看代码，逻辑对我来说似乎很好。虽然可能会导致问题。在代码的第4行，您有：

$this->properties[] = $property;

这意味着你有一系列属性。

但是，您正试图直接访问该对象：

if($this->properties->regionID == $post_code) {
    $this->properties[] = $property;
}

这对我来说很奇怪。您正在尝试查看abject是否具有所需的属性，然后将同一对象保存为数组。

所以我想，一旦你构建了你的$this->properties数组，你只需要循环它并应用你的过滤器来返回一个属性数组，只需要你想要的：

foreach($this->properties as $singleProperty) 
{
    if($singleProperty->regionID == $post_code) 
    {
        $this->foundProperties[] = $singleProperty;
    }
}

过滤数组
