Just a quickie. I had to see if a selected country (selected by 3-letter code) was in Europe, but couldn’t find a handy function online for it.

So, here it is:

function inEurope($code){
  return in_array($code,array(
    'ALB','AND','ARM','AUT','AZE','BLR','BEL','BIH','BGR','HRV','CYP',
    'CZE','DNK','EST','FIN','FRA','GEO','DEU','GRC','HUN','ISL','IRL',
    'ITA','KAZ','LVA','LIE','LTU','LUX','MKD','MLT','MDA','MCO','MNE',
    'NLD','NOR','POL','PRT','ROU','RUS','SMR','SRB','SVK','SVN','ESP',
    'SWE','CHE','TUR','UKR','GBR','VAT'
  ));
}

That returns true or false depending on whether the submitted $code (an “ISO 3166-1 alpha-3” code) is in Europe or not.
