Concatenation of an array

[chuy08]

given the following array:

$sql['city'] = 'Fremont';
$sql['state']= "CA";
$sql['zip'] = "94538"

how would you concatenate these array variables to appear as follows:

Fremont, CA  94538

I have tried the following:

$faddress = ($sql['city'].$sql['state'].$sql['zip']);
print $faddress;

But this returns

FremontCA94538

How do I add spaces to this array concatenation?

Try:
[code]
$faddress = "{$sql['city']}, {$sql['state']}, {$sql['zip']}";
[/code]

[code]echo join(' ', $sql);[/code]
