how to show output?

[ADITYA NAYAK]

1. A text field Like:
Enter Address: ____________________
2. On clicking submit, you should show a value computed by a logic below.
3. Logic:
Make a http call to an url of this format:
http://blockchain.info/q/addressbalance/<address>
Where <address> is the value given above in the text field.
4. The output of the above http call should be zero.
Some sample address are given below:
1933phfhK3ZgFQNLGSDXvqCn32k2buXY8a will return like 20000
1FeexV6bAHb8ybZjqQMjJrcCrHGW9sb6uF will return like 7995705650837
1NibBDZPvJCm568CZMnJUBJoPyUhW7aSag will return 0
HOW TO WRITE CODE FOR THIS??

what have you tried?

What I would do to achieve this ADITYA NAYAK is as followed;

Create a $_POST html fieldset and form, code my script to wait for data to be posted. Using the posted data from the input, I would then use CURL to execute the URL and return the output into a variable where I can manipulate the output, then echo the output to the browser.

Perhaps this might be a good method for you too? Be careful of XSS vulnerabilities in your code.
