Aim. Multiple times (in multiple places) need to check value of array key and based on the value inside foreach need to echo currency code.

Have array (as example), named $data_pvn_1_ii_each_invoice_debit

Array ( 
[0] => Array ( [VatCodeCountryCode] => IE [VatCode] =>123456 ) 
[1] => Array ( [VatCodeCountryCode] => GB [VatCode] =>958725 ) 
)

Here define variable which includes abbreviations of countries, where currency is euro.

$country_codes_with_euro_currency = array( 'AT', 'BE', 'CY', 'DE', 'EE', 'GR', 'ES', 'FI', 'FR', 'IE', 'IT', 'LU', 'MT', 'NL', 'PT', 'SI', 'SK' );

Then multiple times (in multiple places) need to check value of [VatCodeCountryCode] and based on country code need to echo currency

At first trying to get [VatCodeCountryCode].

foreach($data_pvn_1_ii_each_invoice_debit as $i => $result){
$trim_result_vat_country_code = trim($result[VatCodeCountryCode]);
}

Then function (part of function)

function myTest($trim_result_vat_country_code) {

if ( in_array($trim_result_vat_country_code), $country_codes_with_euro_currency) ) {
return $currency_code = 'EUR'; 
}

elseif ( $trim_result_vat_country_code == 'GB' ) {
return $currency_code = 'GBP';
}   

}

And then need to echo currency code (also only part of code)

<?php foreach($data_pvn_1_ii_each_invoice_debit as $i => $result){?>
<tr><td>
<?php echo myTest($trim_result_vat_country_code); ?>
</td></tr>
<tr><td>content of other td</td></tr>
<?php }?>

First problem: code does not work with ( in_array($trim_result_vat_country_code), $country_codes_with_euro_currency) )

Second problem: echo myTest($trim_result_vat_country_code); returns only last result. For array key VatCodeCountryCode there are values IE and GB. So need to echo currencies EUR and GBP. But echo only GBP

First Problem : 

if( in_array($trim_result_vat_country_code), $country_codes_with_euro_currency))

should be 

if( in_array($trim_result_vat_country_code, $country_codes_with_euro_currency))

In in_array function second parameter should be an array.

Second Problem :

foreach($data_pvn_1_ii_each_invoice_debit as $i => $result){
  $trim_result_vat_country_code = trim($result[VatCodeCountryCode]);
}

Your above code holds only the last record.That is why myTest function returns only last records.

Solution : 

<?php foreach($data_pvn_1_ii_each_invoice_debit as $i => $result){?>
<tr><td>
<?php echo myTest($result['VatCodeCountryCode']); ?>
</td></tr>
<tr><td>content of other td</td></tr>
<?php }?>

Modifiy your myTest function

function myTest($trim_result_vat_country_code) {
    global $country_codes_with_euro_currency;
    if ( in_array($trim_result_vat_country_code, $country_codes_with_euro_currency) ) {
        return $currency_code = 'EUR';
    } elseif ( $trim_result_vat_country_code == 'GB' ) {
        return $currency_code = 'GBP';
    }
}
