put this lot outside of the class for whatever currencies your using

global $G_cur;
$G_cur['CURRENCY'] = array(
'CURRENCY_CAD' => array(
'SourceCurSymbol' => 'C$',
'SourceIntlSymbol' => 'CAD'
),
'CURRENCY_EUR' => array(
'SourceCurSymbol' => '€',
'SourceIntlSymbol' => 'EUR'
),
'CURRENCY_USD' => array(
'SourceCurSymbol' => '$',
'SourceIntlSymbol' => 'USD'
),
'CURRENCY_GBP' => array(
'SourceCurSymbol' => 'PD',
'SourceIntlSymbol' => 'GBP'
),
);


and then later on in your class

in the construct declare global $G_cur;

and then can be called whereever in the class

$this->m_fSourceCurSymbol = $G_cur['CURRENCY'][$szCurrencyFrom]['SourceCurSymbol'];
$this->m_fSourceIntlSymbol = $G_cur['CURRENCY'][$szCurrencyFrom]['SourceIntlSymbol'];
$this->m_fTargetCurSymbol = $G_cur['CURRENCY'][$szCurrencyTo]['SourceCurSymbol'];
$this->m_fTargetIntlSymbol = $G_cur['CURRENCY'][$szCurrencyTo]['SourceIntlSymbol'];

hope that sorts it out
