php - PHP 将 XML 的标记值保存到 PHP 变量

Question

嗨，在这行代码之后：
$client = new SoapClient("http://rscnagahrd/OracleWS/Oracle.asmx?WSDL");
$result = $client->getFoods();
$objResult = simplexml_load_string($result->getFoodsResult->any);

我想将标签中的值提取$objResult到 PHP 变量中。

什么时候I var_dump($objResult);

我得到：

object(SimpleXMLElement)#4 (1) { 
["NewDataSet"]=> object(SimpleXMLElement)#5 (1) { 
    ["Table"]=> array(4) { 
        [0]=> object(SimpleXMLElement)#6 (4) { 
            ["FOOD_ID"]=> string(1) "1" 
            ["FOOD_NAME"]=> string(6) "Burger" 
            ["FOOD_DESC"]=> string(15) "100% Beef Patty" 
            ["FOOD_PRICE"]=> string(2) "25" 
        } 
        [1]=> object(SimpleXMLElement)#7 (4) { 
            ["FOOD_ID"]=> string(1) "2" 
            ["FOOD_NAME"]=> string(4) "Coke" 
            ["FOOD_DESC"]=> string(6) "Drinks" 
            ["FOOD_PRICE"]=> string(2) "10" 
        } 
        [2]=> object(SimpleXMLElement)#8 (4) { 
            ["FOOD_ID"]=> string(1) "3" 
            ["FOOD_NAME"]=> string(5) "Pepsi" 
            ["FOOD_DESC"]=> string(6) "Drinks" 
            ["FOOD_PRICE"]=> string(2) "10" 
        } 
        [3]=> object(SimpleXMLElement)#9 (4) { 
            ["FOOD_ID"]=> string(1) "4" 
            ["FOOD_NAME"]=> string(12) "French Fries" 
            ["FOOD_DESC"]=> string(16) "Made from France" 
            ["FOOD_PRICE"]=> string(2) "15" 
        } 
    } 
} 

}

例如，我想将所有带有 TAG“FOOD_NAME”的项目分配给 PHP 变量
$foodname(0)

Answer 1

试试这个：

$foodname = array();
foreach ($objResult->NewDataSet->Table as $table) {
    $foodname[] = $table->FOOD_NAME;
}

echo $foodname[0]; // first element of the array
