Usage and description of php namespace

Namespace is to solve the problem of duplicate names.

For example, there are model files in both directories a and b;
Add namespace a to the beginning of the model file under the name of directory a;

namespacea;
classmodel{
}

Add namespace b to the beginning of the model file under the name of directory b;

namespaceb;
classmodel{
}

When referencing the 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 ').text(i)); }; $numbering.fadeIn(1700); }); });

The above introduces the usage and description of PHP's namespace (namespace), including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
