Do you have a sample conversion rate?

[salman233]

TAKE IT AS AN EXAMPLE LIKE 1EURO=2USD OR 2USD =1 EURO

[phpJoeMo]

OK, so I found these sample rates here:  http://www.x-rates.com/

 

You basically need either an array, or a table in mysql to store the conversion rates.  I think an array would work nicely:

$conversions = array(
    'USD'=>1,
    'GBP'=>1.62343,
    'CAD'=>1.02554
);

 

Having that, you then would neet some way to convert the data.  Probably a function:

function br()
{
echo '<br/>';
}
function converter($need, $have, $value, $conversionArray)
{
($conversionArray[$have] / $conversionArray[$need]) * value;
}
var_dump($conversions);
br();
echo converter('USD', 'GBP', 5.25, $conversions);
br();
echo converter('GBP', 'CAD', 5.25, $conversions);

 

Try it and let me know how it works.

Sorry, did some error testing at the CLI,

 

This works great:

$conversions = array(
    'USD'=>1,
    'GBP'=>1.62343,
    'CAD'=>1.02554
);
function br()
{
echo '<br/>';
}
function converter($need, $have, $value, $conversionArray)
{
return (($conversionArray[$have] / $conversionArray[$need]) * $value);
}
var_dump($conversions);
br();
echo converter('USD', 'GBP', 5.25, $conversions);
br();
echo converter('GBP', 'USD', 5.25, $conversions);
br();
echo converter('GBP', 'CAD', 5.25, $conversions);

REALLY THANKS JOE I AM GOING TO TRY IT PLEASE ELABORATE MORE AS I AM A BEGINNER

[phpJoeMo]

Where would you like me to start?

[salman233]

FROM CREATING TABLE VALUES TO FETCHING THEM I REALLY APPRECIATE YOUR HELP BROTHER

[phpJoeMo]

OK,

 

In the example above we created an 'associative array'.  This basically means that we are identifying the values of the array with 'keys' that contain string values.  IE $conversions['USD'] = 1 in our case above.

 

We created a function that accepts 4 arguments as parameters:

function converter($need, $have, $value, $conversionArray)

$need is the key value we want.

$have is the key value we have.

$value is the amount we have.

$conversionArray is the array containing the Keys / values of our conversions.

 

you can read more at http://www.php.net/manual/en/language.types.array.php,

however I recommend you download the files locally for quicker reference:

http://www.php.net/download-docs.php

 

I have a .chm file on my desktop    I love having it there!

I hate to be the jerk, but you could do some of the coding. This is the "Help forum", not the "free labor" forum.  If you give us bad code, we will help you fix it -- gladly.  If you tell us to do all the work, you should be in the freelance section.

 

edit Just noticed the freelance section is gone. Smeh. PM someone, and offer to pay them.

THANKS JOE U HELPED ALOT MATE

[phpJoeMo]

Hey salman, I don't mind being of help.  Jons does have a point though.  Learning these topics will take a lot of time, trial & error, and studying.  You can do it though!

 

I would start off by installing xampp if you haven't already done so,  you can create databases and tables fairly easy with phpmyadmin.

 

Study the mysql functions in the php docs function->database extensions -> mysql reference.

 

Try out some code, read, learn, try some more, when you run into a wall, come back and start a new thread.

 

Good Luck!
