如何解决这个问题请帮我解决这个问题
<?php if($row->price):?><tr class='"style1'"><td width='200'><b>Price US $:</b></td><td>Price in Dollar:
<?php
function currencyExchange($amount,$baseCurrency,$quoteCurrency) {
$open = fopen("http://quote.yahoo.com/d/quotes.csv?s=$baseCurrency[0]$quoteCurrency[0]=X&f=sl1d1t1c1ohgv&e=.csv", "r");
$exchangeRate = fread($open, 2000);
fclose($open);
$exchangeRate = str_replace("'"", "", $exchangeRate);
$exchangeRate = explode(",", $exchangeRate);
$results = ($exchangeRate[1]*$amount);
$results = number_format ($results, 2);
$amount = number_format ($amount);
$timeStamp = strtotime($exchangeRate[2]);
$timeStamp = date('F d, Y', $timeStamp);
$timeStamp = "$timeStamp $exchangeRate[3]";
echo "$results'n";
}
// for additional currency ticker symbols visit: http://finance.yahoo.com/currency-converter
$usd = array('USD','US Dollars');
$INR = array('INR','Indian Rupees');
$usd = array('usd','US DOLLARS');
$b = str_replace( ',', '', $row->price );
if( is_numeric( $b ) ) {
$row->price = $b;
}
currencyExchange("$b",$INR,$usd);
?></td></tr><?php endif; ?>
在尝试使用仅适用于数字的函数之前，测试金额是否为数字。
替换：
$results = ($exchangeRate[1]*$amount);
$results = number_format ($results, 2);
$amount = number_format ($amount);
带有：
if (is_numeric($amount)) {
$results = ($exchangeRate[1]*$amount);
$results = number_format ($results, 2);
} else {
$results = 'update soon';
}
您不需要在$amount上调用number_format()，因为您从不打印该值。
将列设置为9999999999（这将解决数字问题），然后测试这些数字的传入，如果找到，则很快返回
