我有一個函數foo,它返回一個具有以下結構的數組,我正在努力解決的問題是有沒有更好的方法來構建我的PHP,因爲我不確定每個foreach中的索引, ListingIdCodeigniter身份不明索引

目標:

我想要寫一個foreach循環,從外部XML文檔獲取XML <Name>(沒有編寫本節還因爲我需要從foo通過ListingID進入網址得到<Name>

PHP:

$test0 = $this->foo(); 
    $test = $test0[0]['ListingId']; 

結構:

Array ([0] => Array ([ListingId] => SimpleXMLElement Object ([0] => 532712629) [ListingCategory] => SimpleXMLElement Object ([0] => 0350-5748-3400-)) [1] => Array ([ListingId] => SimpleXMLElement Object ([0] => 532712202) [ListingCategory] => SimpleXMLElement Object ([0] => 0350-5748-3400-)) [2] => Array ([ListingId] => SimpleXMLElement Object ([0] => 532711566) [ListingCategory] => SimpleXMLElement Object ([0] => 0350-5748-3400-)) [3] => Array ([ListingId] => SimpleXMLElement Object ([0] => 532710864) [ListingCategory] => SimpleXMLElement Object ([0] => 0350-5748-3400-)) [4] => Array ([ListingId] => SimpleXMLElement Object ([0] => 532710271) [ListingCategory] => SimpleXMLElement Object ([0] => 0350-5748-3400-)) [5] => Array ([ListingId] => SimpleXMLElement Object ([0] => 532691526) [ListingCategory] => SimpleXMLElement Object ([0] => 0350-5748-3400-)) [6] => Array ([ListingId] => SimpleXMLElement Object ([0] => 527496168) [ListingCategory] => SimpleXMLElement Object ([0] => 0350-5748-3399-)))

你能澄清?我已經重讀了幾次,並不確定你在問什麼 –

這裏一樣。把一些預期的產出。可能是那麼清楚。 – itachi

@DavidNguyen我同意已經改變 –

試試這個方法:

foreach($this->foo() as $foo) { 
    //here you can use your ListingId 
    var_dump($foo['ListingId']); 
}
