如果没有大括号可以说明它有多少陈述？ [关闭]

Question

OK, I got the answer. It was not so clear to me in PHP documentation. Thanks

I know, this question is simple, but I unfortunately I cannot answer it by myself :(

So, the question is, when some developer uses the if statement without braces, for how many lines next to if statement the if works?

More specific, let's say I have the following code:

if(1 == 1)
    SayHello();
    SayYourName('Nikos');
    SayYourAge(32);

Will all of this function calls be executed if the 1 is equal to 1? Or will it execute only the first one?

Answer 1

if condition without {} will only execute first statement, In your case.

if(1 == 1)
    SayHello();
    SayYourName('Nikos');
    SayYourAge(32);

SayHello(); will only be executed when if condition will satisfy now other two line will also execute.
