IF needs brackets around the expression,

if ( empty($datalanguage) )
      {
      $datalanguage="0";
      }
      else
      {
      $datalanguage= $datalanguage;
      }
0

On an additional matter, code styling..... the IF layout you are using is uncommon but not unknown. It is considered "better" to align the ELSE with its matching IF so that it is obvious that they are related. If you nest multiple IF statements the reason for this becomes obvious. So rather than

if ( empty($datalanguage) )
      {
      $datalanguage="0";
      }
      else
      {
      $datalanguage= $datalanguage;
      }


More like this

if ( empty($datalanguage) )
      {
      $datalanguage="0";
      }
else
      {
      $datalanguage= $datalanguage;
      }


or (my preference)

if ( empty($datalanguage) )  {
      $datalanguage="0";
}
else  {
      $datalanguage= $datalanguage;
}


and for single statements it is not unusual to skip the compounding braces


if ( empty($datalanguage) )  
      $datalanguage="0";
else  
      $datalanguage= $datalanguage;
