Google is a wonderful ! While most of us use it for searching the web for information , few are aware that it has an inbuilt calculator which can also be used for converting a currency into another . Doing so is really simple , you just type ” AMOUNT CURRENCY_CONVERTING_FROM in CURRENCY_CONVERTING_TO ” and search , the inbuilt calculator will give you the result .For example , if one wants to convert 1 U.S Dollar into Euro , he shall type “1 USD in EUR” .
Now lets get to the topic of this post , Google also has a secret calculator API ( http://www.google.com/ig/calculator ) that is usually used for iGoogle gadgets , but since its free and open , anyone can use it .
So if you want to convert a currency into another using the API , your callback URL would look like :
www.google.com/ig/calculator?hl=en&q=AMOUNT-FROM_CURRENCY=?TO_CURRENCY
// 1 USD in EUR example
www.google.com/ig/calculator?hl=en&q=1USD=?EUR
In the above example , you get a string which looks like "{lhs: "1 U.S. dollar",rhs: "0.838574423 Euros",error: "",icc: true}" . You can easily explode() the string using php and extract the required data .
To make things easier for you , here is a simple php function that converts a currency into another using the Google calculator API . This example uses cURL , so you have to have it enabled for this code to work .
To make things easier for you , here is a simple php function that converts a currency into another using the Google calculator API . This example uses cURL , so you have to have it enabled for this code to work .
The value returned by Google usually has 9 decimal places , you can round it off to a no. of digits after decimal of you choice using the round() function . By default the above function rounds the value to 3 digits after decimal .
Now here is how you can use the function in your scripts
Hope this has helped you with converting currencies using php on your website
Enum是计算机编程语言中的一种数据类型---枚举类型。 在实际问题中，有些变量的取值被限定在一个有限的范围内。 例如，一个星期内只有七天 我们通常这样实现上面的定义：
