没有{？有可能使用die / echo等吗？

Question

So, Well I was wondering, Is it possible to do this;

if($pro == true)
    echo "He's";
    echo "a";
    echo "pro.";

Or do I need to use { } ? Thanks.

Answer 1

It depends on your intentions. With your code

if($pro == true)
    echo "He's";
    echo "a";
    echo "pro.";

The result (if $pro is true) will be:

He'sapro.

If $pro is false it will be

apro.

If you don't want that output on false, please add the braces.

if($pro == true) {
    echo "He's ";
    echo "a ";
    echo "pro.";
}
