What Namespaces are in PHP? Live online class just for 10 USD.
The PHP namespaces are way of encapsulating some items. We can understand the namespace with the explanation of directory structure in an operating systems. We can not store different files with the unique name in a directory. We can store different files with unique name in separate directories. We should mention full path of the file to open from a command prompt. The same principle will be used in the PHP programming language also.
The three types of php code are affected by namespaces, they are classes, functions and constants. The keyword ‘namespace’ keyword will be used to declare the namespace at the top of the php file before any other code.
We can also declare sub-namespaces just like directories and files in hierarchical structure of a file system. We can declare multiple namespaces in the same php file. It is recommended to use the bracketed syntax for each name space. This not a good idea to combine different namespaces into same file. The primary use of defining multiple namespaces in same php file is to combine multiple php scripts into the same file. PHP code should not exist outside of the namespace except for an opening declare statement.
