Up until yesterday I had a perfectly working budget organizer site/app working with iGoogle.
Through PHP, using the following little line
file_get_conten
Still a very useful solution by QuestionerNo27. Since early 2015, however, Yahoo YQL apparently slightly changed the XML output of their api. 'Name' now no longer translates into a string like 'USD to EUR', but to 'USD/EUR' and should in the code above be referenced this way:
$toeur = array(
'usd' => $exchange['USD/EUR']
instead of
$toeur = array(
'usd' => $exchange['USD to EUR']
and in a similar fashion for other currency conversions.
Never mind! Solved it!
For anyone interested, here's what I did to get my code to work (with the least chnges possible) with the Yahoo YQL:
// ** GET EXCHANGE INFO FROM YAHOO YQL ** //
$url = 'http://query.yahooapis.com/v1/public/yql?q=select * from yahoo.finance.xchange where pair in ("USDEUR", "EURUSD")&env=store://datatables.org/alltableswithkeys'; //<-- Get the YQL info from Yahoo (here I'm only interested in converting from USD to EUR and vice-versa; you should add all conversion pairs you need).
$xml = simplexml_load_file($url) or die("Exchange feed not loading!"); //<-- Load the XML file into PHP variable.
$exchange = array(); //<-- Build an array to hold the data we need.
for($i=0; $i<2; $i++): //<-- For loop to get data specific to each exchange pair (you should change 2 to the actual amount of pairs you're querying for).
$name = (string)$xml->results->rate[$i]->Name; //<-- Get the name of the pair and turn it into a string (this looks like this: "USD to EUR").
$rate = (string)$xml->results->rate[$i]->Rate; //<-- Do the same for the actual rate resulting from the conversion.
$exchange[$name] = $rate; //<-- Put the data pairs into the array.
endfor; //<-- End for loop. :)
// ** WORK WITH EXCHANGE INFO ** //
$toeur = array( //<-- Create new array specific for conversion to one of the units needed.
'usd' => $exchange['USD to EUR'], //<-- Create an array key for each unit used. In this case, in order to get the conversion of USD to EUR I ask for it from my $exchange array with the pair Name.
'eur' => 1); //<-- The way I coded the app, I found it more practical to also create a conversion for the unit into itself and simply use a 1, which translates into "do not convert"
$tousd = array(
'eur' => $exchange['EUR to USD'],
'usd' => 1);
This is basically all you need to get all the exchange info you want. After that, you use it all something like this:
amount*$toxxx['coin'];
So, say I wanted to know how many Euro is 100 USD right now:
100*$toeur['usd'];
Piece of cake!
I created a routine to convert the currency based on @QuestionerNo27 http://jamhubsoftware.com/geoip/currencyconvertor.php?fromcur=USD&tocur=EUR&amount=1 you can consume this
<?php
$fromcur = $_GET['fromcur'];
$tocur = $_GET['tocur'];
$amt = $_GET['amount'];
// ** GET EXCHANGE INFO FROM YAHOO YQL ** //
$url = 'http://query.yahooapis.com/v1/public/yql?q=select * from yahoo.finance.xchange where pair in ("'.$fromcur.$tocur.'")&env=store://datatables.org/alltableswithkeys'; //<-- Get the YQL info from Yahoo (here I'm only interested in converting from USD to EUR and vice-versa; you should add all conversion pairs you need).
$xml = simplexml_load_file($url) or die("Exchange feed not loading!"); //<-- Load the XML file into PHP variable.
$exchange = array(); //<-- Build an array to hold the data we need.
for($i=0; $i<2; $i++): //<-- For loop to get data specific to each exchange pair (you should change 2 to the actual amount of pairs you're querying for).
$name = (string)$xml->results->rate[$i]->Name; //<-- Get the name of the pair and turn it into a string (this looks like this: "USD to EUR").
$rate = (string)$xml->results->rate[$i]->Rate; //<-- Do the same for the actual rate resulting from the conversion.
$exchange[$name] = $rate; //<-- Put the data pairs into the array.
endfor; //<-- End for loop. :)
// ** WORK WITH EXCHANGE INFO ** //
$conv = $fromcur . '/' . $tocur;
$toeur = array( //<-- Create new array specific for conversion to one of the units needed.
$tocur => $amt*$exchange[$conv], //<-- Create an array key for each unit used. In this case, in order to get the conversion of USD to EUR I ask for it from my $exchange array with the pair Name.
$fromcur => $amt,
"ex_amt" =>$amt*$exchange[$conv]); //<-- The way I coded the app, I found it more practical to also create a conversion for the unit into itself and simply use a 1, which translates into "do not convert"
echo json_encode($toeur);
