Php namespace usage and description

: This article mainly introduces the usage and description of php namespace. if you are interested in PHP tutorials, refer to it. The namespace solves the problem of duplicate names.

For example, both directory a and directory B have model files;
Add namespace a to the beginning of the model file under directory;

Namespacea; classmodel {}

Add namespace B to the beginning of the model file under directory B;

Namespaceb; classmodel {}

When referencing a file, new/space name/class name (model here)

Require ("a \ model. class. php"); $ model = new/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) ;}) ;}; script

The above describes the usage and description of php namespace (namespace), including some content, and hope to help those who are interested in PHP tutorials.
