我正在尝试使用php读取json对象,如下所示:
I am trying to read a json object using php as follows

$jsonres = json_decode($jsonObject, true);

{"Data":"[{\"CurrencySymbol\":\"AU$\",\"CurrencyDescription\":\"Austrailian Dollar\",\"CurrencyRate\":135.42,\"CurrencyType\":\"AUD\",\"RequestDate\":\"\\\/Date(1408041000000)\\\/\",\"PolicyId\":\"\",\"QuotationId\":0,\"SellingRate\":135.42},{\"CurrencySymbol\":\"£.\",\"CurrencyDescription\":\"British pound sterling\",\"CurrencyRate\":212.62,\"CurrencyType\":\"GBP\",\"RequestDate\":\"\\\/Date(1408041000000)\\\/\",\"PolicyId\":\"\",\"QuotationId\":0,\"SellingRate\":212.62},{\"CurrencySymbol\":\"EURO\",\"CurrencyDescription\":\"Euro\",\"CurrencyRate\":171.2,\"CurrencyType\":\"EUR\",\"RequestDate\":\"\\\/Date(1408041000000)\\\/\",\"PolicyId\":\"\",\"QuotationId\":0,\"SellingRate\":171.2},{\"CurrencySymbol\":\"¥.\",\"CurrencyDescription\":\"Japanese yen\",\"CurrencyRate\":1.6809,\"CurrencyType\":\"JPY\",\"RequestDate\":\"\\\/Date(1408041000000)\\\/\",\"PolicyId\":\"\",\"QuotationId\":0,\"SellingRate\":1.6809},{\"CurrencySymbol\":\"SIN$\",\"CurrencyDescription\":\"Singapore Dollar\",\"CurrencyRate\":107.3,\"CurrencyType\":\"SGD\",\"RequestDate\":\"\\\/Date(1408041000000)\\\/\",\"PolicyId\":\"\",\"QuotationId\":0,\"SellingRate\":107.3},{\"CurrencySymbol\":\"Rs.\",\"CurrencyDescription\":\"Sri Lankan Rupees\",\"CurrencyRate\":1,\"CurrencyType\":\"LKR\",\"RequestDate\":\"\\\/Date(1408041000000)\\\/\",\"PolicyId\":\"\",\"QuotationId\":0,\"SellingRate\":1},{\"CurrencySymbol\":\"CHF\",\"CurrencyDescription\":\"Swiss Frank\",\"CurrencyRate\":141.71,\"CurrencyType\":\"CHF\",\"RequestDate\":\"\\\/Date(1408041000000)\\\/\",\"PolicyId\":\"\",\"QuotationId\":0,\"SellingRate\":141.71},{\"CurrencySymbol\":\"US$.\",\"CurrencyDescription\":\"United States dollar\",\"CurrencyRate\":135,\"CurrencyType\":\"USD\",\"RequestDate\":\"\\\/Date(1408041000000)\\\/\",\"PolicyId\":\"\",\"QuotationId\":0,\"SellingRate\":137}]","ID":1}
我需要在html选择中列出货币,我用下面的方法列出了货币.
I need to list down currency in a html selection and i used following to do so.
echo '<select>';
foreach($jsonres->Data as $option)
{ echo '<option value=' . $option->CurrencyDescription . '>' . $option->CurrencyDescription . '</option>';
}
echo '</select>';
结果是我得到一个空选择,我需要加载"CurrencyDescription"作为选项值.请帮我解决一下这个.并请解释我犯了什么错误,因为我是php和json的新手.
I am getting an empty selection as a result and i need to load 'CurrencyDescription ' as option value. Please help me with this. and please explain what is the error i made because i am new to php and json.
完整代码如下
<?php
$jsonObject = file_get_contents("http://10.12.12.189:9080/NonMotorServices/CommonServices.svc/FetchCurrency");
$jsonres = json_decode($jsonObject, true);
echo '<select>';
foreach($jsonres->Data as $option)
{ echo '<option value=' . $option->CurrencyDescription . '>' . $option->CurrencyDescription . '</option>';
}
echo '</select>';
