板邓:PHP解决Using $this when not in object context in【转】 错误信息:$this引用没有上下文 原因:在PHP5中,static声明的静态方法里不可以使用$this 需要使用self来引用当前类中的方法或是变量。 示例代码如下: <?php namespace syhl\admin\page\record;//命名空间require_once
<?phpclass test {private $a;function t1( ){$this->a=1;//调用属性方式不正确(下面同理) $this->a=1;print $this->$a;// print($this->a); 这里不加括号写空格也是可以的;}function t2( ){$this->$a=2;//$this->a=2;print $this->$a;// print($this->a);}}$re=...

Using $this when not in object context ,一般来说,当你使用某个类,而这个类并没有进行实例化的时候就会出现这种错误。据我的理解,你可能是还没有理解静态变量(函数)和常规类的实例变量的区别,在PHP里,有static修饰的变量和函数不能出现$this。建议你再看看PHP帮助手册里,有关 static 静态...
