a. : PHP的名称方法
原标题:self:: vs className:: inside static className methods in PHP

我猜测可能没有任何区别,而是个人偏好,但在阅读各种购买力平价代码时,我有两种途径进入方法类别。

∗∗∗ 差异:

class Myclass
{
    public static $foo;

    public static function myMethod ()
    {
        // between:
        self::$foo;
        // and
        MyClass::$foo;
    }
}
最佳回答

(说明:初步版本说没有区别。) 实际存在

确实有小的分歧。 序号:n t。 这只有在PHP5.3+中贴有固定约束力的

在静态电话中,PHP5.3+记住最初称为一类。 使用<代码>Name:使PHP“forget”这一数值(即,转至}Name),而sol: 考虑:

<?php
class A {
    static function foo() {
        echo get_called_class();
    }
}
class B extends A {
    static function bar() {
        self::foo();
    }
    static function baz() {
        B::foo();
    }
}
class C extends B {}

C::bar(); //C
C::baz(); //B
问题回答

如果你能够自食其力,并用“MyClass”。

$instance = new Myclass();
$variable = $instance::$foo
