Call to undefined function

I am trying to call a method from a different class in a different file. However, When I run the code i get the following error:

Fatal error: Call to undefined function getFxRate() in fxCalc.php

Here is the code I am trying to build:

fxCalc.php

//call fxDataModel class
require_once('fxDataModel.php');
$fxRate = getFxRate($inputCurrency, $outputCurrency);
$txtOutput = $txtInput * $fxRate;

fxDataModel.php

   public static function getFxRate($inputCurrency, $outputCurrency)
    {
        $fxRate = $currencies[$inputCurrency][$outputCurrency];
        return $fxRate;
    }

Any help would be appreciated.

Say if your name of the class infxDataModel.php is FxModel

Then you need to call your method like

$fxRate = FxModel::getFxRate($inputCurrency, $outputCurrency);

instead of

$fxRate = getFxRate($inputCurrency, $outputCurrency);

That is because your function is declared as static. The static calls are made by using :: operator followed by the class name.
