mantis - php T_STRING error

While configuring custom fields in mantis i got this error message , any idea

Parse error: syntax error, unexpected T_STRING in
C:\wamp\www\MyProj\custom_strings_inc.php on line 3

The code is

if( lang_get_current() == 'german' ) {
    $defect_impact = 'Defect Impact'; #// German translation of Defect Impact
    $defect_type =  'Defect Type'; #// German translation of Defect Type
    $phase_of_origin =  ’Phase Of Origin’; #// German translation of Phase Of Origin
}else{
# Default (use your preferred language as the default)
    $defect_impact = 'Defect Impact'; // German translation of Defect Impact
    $defect_type =  'Defect Type'; // German translation of Defect Type
    $phase_of_origin =  'Phase Of Origin'; // German translation of Phase Of Origin

}
?>

Answer

Wrong quotes on this line:

$phase_of_origin =  ’Phase Of Origin’;

Should be:

$phase_of_origin =  'Phase Of Origin';
