[RESOLVED] Mixing array elements with a variable string

$lang = array(
'city'  => 'Dallas',
'stateabb'  => 'TX'
);

$title = "About {$lang['city']}, {$lang['stateabb']} USA";
$title = "About " . {$lang['city']} . ", " . {$lang['stateabb']} . " USA";
$title = "About " . $lang['city'] . ", " . $lang['stateabb'] . " USA";
$title = "About " . $lang['city']; . ", " . $lang['stateabb']; . " USA";
$title = "About $lang['city'];, $lang['stateabb']; USA";

I can't seem to get this to work. I either get an error message or the city and state is blank.

// yes:
$title = "About {$lang['city']}, {$lang['stateabb']} USA";

// no (mixing concatenation and complex notation:
$title = "About " . {$lang['city']} . ", " . {$lang['stateabb']} . " USA";

// yes:
$title = "About " . $lang['city'] . ", " . $lang['stateabb'] . " USA";

// no (first semicolon terminates statement):
$title = "About " . $lang['city']; . ", " . $lang['stateabb']; . " USA";

// no (need complex notation [curly braces] when using quoted array key within double-quoted string):
$title = "About $lang['city'];, $lang['stateabb']; USA";

Don't forget the sprintf function, this can also help with string formatting

$title = sprintf( "About %s, %s USA", $lang['city'], $lang['stateabb']);

And when it gets at all complex, you can break everything into separate lines:

$text = sprintf(
    "blah blah blah %s blah blah %f blah blah blah %s.",
    preg_replace('/\s+/', ' ', $foo['bar'],
    $foo['total'] / $foo['num_entries'],
    date('Y-m-d', $foo['date'])
);

...which keeps things pretty compact while still being pretty readable (and maintainable).

Thanks to both of you for the information. It was a great help! I'll study up on the sprintf function, sounds interesting.
Thanks again.
