PHP namespace (namespace) usage and description

Namespaces are the problem of resolving duplicate names.

For example, A and B two directories have a model file;
Add namespace A at the beginning of the model file named under Directory A;

namespacea;classmodel{}

Give namespace B at the beginning of the model file under the B catalogue;

namespaceb;classmodel{}

New/Spatial Name/class name when referencing a file (model here)

require("a\model.class.php");$modelnew  /a/model;

'). addclass (' pre-numbering '). Hide (); $ (this). addclass (' has-numbering '). Parent (). append ($numbering); for (i = 1; i <= lines; i++) {$numbering. Append ($ ('

'). Text (i)); }; $numbering. FadeIn (1700); }); });

The above describes the PHP namespace (namespace) usage and description, including the aspects of the content, I hope that the PHP tutorial interested in a friend helpful.
