use variable in a construct sintax?

[eluser]chefnelone[/eluser]
Hello
I need to use a variable in this sintax:

Code:

echo $photos->title;?>

Something like:

Code:

$_SESSION['lang_txt'] = '_en';
// THEN I NEED: $photos->title_en;

// TRIED WITH:
echo $photos->title.$_SESSION['lang_txt'];
//BUT...NOT WORKING


// IT DOES THE JOB WITH THIS:
$title_lang = 'title'.$_SESSION['lang_txt'];
echo $photos->$title_lang;

//BUT I'M LOOKING TO DO IT IN ONE SINGLE LINE...

thanks

Assuming the object property title_en exists, you can use

Code:

echo $photos->{'title'.$_SESSION['lang_txt']};
