I'm having a folder path which I need to concatenate with subfolder which is being stored in variable for ex:
I've a path somepath\theme
now I want to add theme named in the folder something like this somepath\theme\themeone
I've this themeone stored in variable and trying to concatenate
$themename = 'themeone';
$path = 'somepath\theme\' . $themename;
I'm getting an error unexpected end of file.
Look at the syntax highlighting. You're last slash is escaping the apostrophe causing your string to not terminate. As a result you are left with an open string. You need to escape that backslash.
$themename = 'themeone';
$path = 'somepath\\theme\\' . $themename;
