你正在对网址进行urlencoding，这会破坏网址。尝试

$url = "http://query.yahooapis.com/v1/public/yql?q=";
$url .= urlencode("select * from yahoo.finance.xchange where pair in ('USDUSD','USDEUR','USDGBP','USDINR','USDAED','INRINR','INREUR','INRGBP','INRAED','INRUSD')");
$url .= "&env=";
$url .= urlencode("store://datatables.org/alltableswithkeys"));

修改

首先没有看到第二个GET参数，更新了代码。
