添加一些文本到PHP代碼 - 爲傻瓜

Question

在此先感謝您閱讀此。

我對PHP或編碼一無所知，我一直在試圖遵循一些互聯網指南，爲一段代碼添加一些文字。該代碼用於執行一些自動貨幣轉換，並將其嵌入到在彈出窗口中打開的文章中。

我拼命地試圖在每個單獨的轉換前添加幾個字。我已經添加了下面的代碼 - 輸出是最後三行，並且我想在每行前添加一些文本（每行不同的文本），但是我一直遇到麻煩，我可以' t看起來沒錯。

我會非常感激任何想法，我甚至不確定這是可能的。

我想在最後三行的前面添加一些內容。

這可能嗎？我會感謝任何和所有的想法，在此感謝您的時間。

最良好的祝願， 本

試試這個：

Answer 2

雖然最後三行調用貨幣轉換，輸出實際上是所有在這一行做了：

echo "$amount $baseCurrency[1] = $results $quoteCurrency[1]<br>"; 

您可以添加y文本，您想要該行的開始，並且它將反映在每次轉換的輸出中。例如：

echo "Look some extra text $amount $baseCurrency[1] = $results $quoteCurrency[1]<br>"; 

發生了什麼是最後三行中的每一行運行函數currencyExchance（）。該功能使用echo命令打印輸出。 echo命令只是輸出文本（你把它放在引號中）或php變量。

希望有所幫助。

Answer 3

如果你想改變輸出到包括在前面一些文本功能currencyExchange的輸出是在底部，這樣的：

echo "$amount $baseCurrency[1] = $results $quoteCurrency[1]<br>"; 

這樣你就可以添加這些類似的話，每次你調用currencyExchange它會添加這些話

echo "Some Extra Words $amount $baseCurrency[1] = $results $quoteCurrency[1]<br>"; 

或修改方法類似@patrick建議之前，我可以打後到接受可變3個字。 :)

Answer 4

您的函數立即回聲的結果，這是恕我直言，不理想。所以，而不是引入第四個參數，我會做以下。

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, 0); 
$amount = number_format ($amount); 
$timeStamp = date('F d, Y'); 
$timeStamp = "$timeStamp $exchangeRate[3]"; 

return "$amount $baseCurrency[1] = $results $quoteCurrency[1]"; 
$timestamp; 
} 

// for additional currency ticker symbols visit: http://finance.yahoo.com/currency-converter 
$usd = array('USD','USD'); 
$eur = array('EUR','Euro'); 
$jpy = array('JPY','Japanese Yen'); 
$gbp = array('GBP','British Pounds'); 
$aud = array('AUD','Australian Dollars'); 
$chf = array('CHF','Swiss Francs'); 
$cad = array('CAD','Canadian Dollars'); 
$krw = array('KRW','KRW'); 

// amount, base currency, quote currency. 
echo "the result is ".currencyExchange("25",$usd,$krw); 
echo "Blabla ".currencyExchange("20",$usd,$krw); 
echo "TEST: ".currencyExchange("39",$usd,$krw); 

?> 

這使您可以更加靈活地處理輸出，將結果包裝在一個表中。

echo "<table>"; 
echo "<tr><td>first request </td><td>".currencyExchange("25",$usd,$krw)."</td></tr>"; 
echo "<tr><td>next</td><td>".currencyExchange("20",$usd,$krw)."</td></tr>"; 
echo "<tr><td>and so</td><td>".currencyExchange("39",$usd,$krw)."</td></tr>"; 
echo "</table>"; 

我認爲應該將函數的目的從你對結果做的事情中分離出來。
