Pseudo "Multi-inheritance" of PHP5.4 and above -- trait syntax, php5.4 -- trait

In earlier versions of PHP, classes cannot implement multi-inheritance. Therefore, we must consider "chain inheritance" when we want to achieve multi-inheritance. In later versions of PHP, trait syntax is updated, to implement "Multi-inheritance"

<? Php

 

Trait PHP

{

Public function pcode ()

{

Echo 'I can write PHP Code ';

}

}

Trait Java

{

Public function jcode ()

{

Echo 'I can write JAVA Code ';

}

}

Class Stu

{

Use PHP, Java;

}

$ Stu = new Stu;

$ Stu-> pcode (); // output result I can write PHP code

$ Stu-> jcode (); // The output result is that I can write PHP code. I can write JAVA code.
