$this->set_current_page( $page )这句里面的set_current_page是什么意思呢？
这个不是属性是方法吧前面也没有定义啊

<code>class Java_Pagination
{
    protected $_total = 0;
    protected $_total_page = 0;
    protected $_page = 1;
    protected $_page_size = 10;
    protected $_link = '';
    protected $_grep = 3;
 
    protected $_admin = false;
    protected $_css_next = 'next-page';
    protected $_css_prev = 'prev-page';
    protected $_css_curr = 'curr-page';
    protected $_css_page = 'page-nav inline-block';
 
    public function __construct ( $page, $page_size, $total, $admin = false )
    {
        $this->set_current_page( $page );
        $this->set_page_size( $page_size );
        $this->set_total( $total );
 
        if ( $admin )
        {
            $this->_admin = $admin;
        }
        //$this->_link = $_SERVER['REQUEST_URI'];
        $this->set_link( $_SERVER['REQUEST_URI'] );
    }
    }</code>

两种可能：

1.你没有把代码看全，下面有这个类方法；

2.这个类是不是继承了其他类，即：

<code class="php">class Java_Pagination extends SomeClass
{
    //your code...
}</code>

这个类没有继承么？

类或父类的方法set_current_page

这个好像是ThinkPHP里面的数据库操作

有一种可能是需要子类实现

你代码应该没有看全，有继承别的类，或者下方有实现该方法.单单是这样的话 php 是会自己报错的
