Use In Traits¶
use is a keyword for traits and classes: it imports another trait in the current structure.
The import federates all the defined structures in both traits and classes: the methods, the properties and the constants.
There may be naming conflicts between the imported traits and the host structure: the conflicts may be between an import and the host structure, or between two distinct imported traits.
In that case, there is a mechanism to resolve the conflicts: the insteadof keyword allows the host to choose between several competing implementation.
The as keyword is also available to create aliases from the import structures. These aliases shall not introduce new naming conflicts.
<?php
trait T {
function foo() {}
}
trait T2 {
use T {
T::foo as goo; // aliasing
T::foo insteadof foo; // aliasing
T2::foo as hoo; // aliasing
}
function foo() {}
}
?>
