我的代碼是：$xml = simplexml_load_file('http://www.floatrates.com/daily/gel.xml');        $cur = array($xml);$array = json_decode(json_encode($cur), true);$newArr = [];foreach ($array as $value) {    foreach($value['item'] as $key){        array_push($newArr, [ $key['targetCurrency'] => $key ]);        print '<pre>'; print_r($newArr); print '</pre>';    }}輸出為https://prnt.sc/terpnc我需要像這個例子一樣：[USD] => Array(    [title] => 1 GEL = 0.32613048 USD    [link] => http://www.floatrates.com/gel/usd/    [description] => 1 Georgian lari = 0.32613048 U.S. Dollar    [pubDate] => Thu, 9 Jul 2020 12:00:01 GMT    [baseCurrency] => GEL    [baseName] => Georgian lari    [targetCurrency] => USD    [targetName] => U.S. Dollar    [exchangeRate] => 0.32613048    [inverseRate] => 3.06625741    [inverseDescription] => 1 U.S. Dollar = 3.06625741 Georgian lari)[EUR] => Array(    [title] => 1 GEL = 0.28808543 EUR    [link] => http://www.floatrates.com/gel/eur/    [description] => 1 Georgian lari = 0.28808543 Euro    [pubDate] => Thu, 9 Jul 2020 12:00:01 GMT    [baseCurrency] => GEL    [baseName] => Georgian lari    [targetCurrency] => EUR    [targetName] => Euro    [exchangeRate] => 0.28808543    [inverseRate] => 3.47119257    [inverseDescription] => 1 Euro = 3.47119257 Georgian lari)我怎樣才能像示例中那樣做到這一點？順便說一句，使用我的代碼，我多次獲得相同的值，例如您可以看到 [USD] => 數組 149 次。
