如何在PHP中连接字符串？

Question

I have three strings:

$str1 = "abc"; $str2 = "def"; $str3 = "ghi";

I can get the value of all of them like this:

echo "$str1$str2$str3";

But I heard there is a way to join them together, so I can echo all of them without quotes.

You're looking for string concantation.

It's

echo $str1 . $str2 . $str3;

See http://nz2.php.net/language.operators.string for more information.
