如何在php中获取SimpleXMLElement中的数组元素？

$xml = '<root>
            <fruits>
                <fruit>
                    <name>Apple</name>
                    <color>Red</color>
                </fruit>
                <fruit>
                    <name>Banana</name>
                    <color>Yellow</color>
                </fruit>
            </fruits>
        </root>';

// 将XML字符串转换为SimpleXMLElement对象
$simpleXml = new SimpleXMLElement($xml);

// 获取fruits元素下的所有fruit元素
$fruits = $simpleXml->fruits->children();

// 遍历fruit元素并获取数组元素
foreach ($fruits as $fruit) {
    $name = (string) $fruit->name;
    $color = (string) $fruit->color;
    
    echo "Fruit: $name, Color: $color" . PHP_EOL;
}

Fruit: Apple, Color: Red
Fruit: Banana, Color: Yellow
