How to inherit static methods in php

How to inherit static methods in php:

Before, I have been wondering whether subclasses can override static functions. , so I wrote a test code, the code is as follows:

<?php
Class A
{
var $a=&#39;I/&#39;m A&#39;;
function write()
{
echo &#39;I can be overriden!<br />&#39;;
}
static function no_write()
{
echo &#39;Can I be overriden?<br />&#39;;
}
 
}
 
Class B extends A
{
function write()
{
echo &#39;Override from A successfully!<br />&#39;;
}
static function no_write()
{
echo &#39;Can I override successful?<br />&#39;;
}
}
$a=new A;
$a->write();
$a->no_write();
 
$b=new B;
echo $b->a.&#39;<br />&#39;;  //Attributes can be inherited
$b->write();
$b->no_write();       //static methods can be overriden
?>
Copy after login

The running results are as follows:

I can be overriden!
Can I be overriden?
I&#39;m A
Override from A successfully!
Can I override successful?
Copy after login

So, static functions can be overridden in subclasses, but not in java It’s so clear, I’m going to write some more code myself to test it. a
