There are two php files in the same directory
Question:
How do I call the static methods of class a and class b in index.php respectively in class c in indexb.php?
How to fill in namespace and use?
File 1: index.php
<code>namespace {
use
class a{
static public function speak($a)
{
echo $a;
}
}
}
namespace {
use
class a{
static public function speak($a)
{
echo $a.$a;
}
}
}
</code>
File 2: indexb.php
<code>namespace Php {
class c
{
}
}</code>

{
}
}</code>
File index.php:
<code><?php
namespace A{
class A{
static public function speak($a)
{
echo $a;
}
}
}
namespace B{
class B{
static public function speak($a)
{
echo $a;
}
}
}</code>
File indexb.php
<code><?php
namespace PHP{
use A\A;
use B\B;
class C{
public static function test(){
include "index.php";
A::speak("I am A!");
B::speak("I am B!");
}
}
//测试
\PHP\C::test();
}</code>
Run indexb.php and the result is I am A! I am B!
Is this the result you want?
index.php
<code><?php
namespace test{
class a
{
static public function speak($a)
{
echo $a;
}
}
}
namespace test2{
class b
{
static public function speak($a)
{
echo $a.$a;
}
}
}</code>
indexb.php
<code><?php
namespace testt{
include 'index.php';
use test\a;
use test2\b;
class c
{
public $a;
public function speak()
{
// var_dump(new a);
// \test\a::speak($this->a);
a::speak($this->a);
// \test2\b::speak($this->a);
b::speak($this->a);
}
}
$c = new \testt\c();
$c->a = 'zhansan';
$c->speak();
}</code>
