PHP Namespace Syntax: What is the Difference with Braces vs. without Braces? -

php offers 2 syntax declaring namespaces. can use namespace no braces or braces seen below.

without braces

namespace foo/bar; class any{} 

with braces

namespace foo/bar {    class any{} } 

is there difference in functionality or behavior of these 2 ways of using namespaces or both work/function same way?

there different reasons each case, there good example on php site.

the reason you'd use curly brackets around namespace if there multiple namespaces in 1 file or need have global non-namespaced code in same file code contained within namespace.

also if there multiple namespaces in 1 file, non-bracketed syntax allowed well.

as per php guidelines not recommended , if can, keep 1 namespace per file.
