tp5分页效果，中间数字化的设置。

核心分页默认文件的路径：tp5\thinkphp\library\think\paginator\driver\Bootstrap.php

 /**
     * 页码按钮
     * @return string
     */
	 /*
    protected function getLinks()
    {
}

这个函数是我们要修改替换的！

我这里推荐一个：http://www.thinkphp.cn/code/3000.html

 public $rollPage=1;//侧面显示个数
protected function getLinks()
 {
 if ($this->simple)
 return '';
 
 $block = [
 'first' => null,
 'slider' => null,
 'last' => null
 ];
 
 $side = $this->rollPage;
 $window = $side * 2;
 
 if ($this->lastPage < $window +1) {
 $block['slider'] = $this->getUrlRange(1, $this->lastPage);
 
 } elseif ($this->currentPage <= $window-1) {
 
 $block['slider'] = $this->getUrlRange(1, $window + 1);
 } elseif ($this->currentPage > ($this->lastPage - $window+1)) {
 $block['slider'] = $this->getUrlRange($this->lastPage - ($window), $this->lastPage);
 
 } else {
 
 $block['slider'] = $this->getUrlRange($this->currentPage - $side, $this->currentPage + $side);
 }
 
 $html = '';
 
 if (is_array($block['first'])) {
 $html .= $this->getUrlLinks($block['first']);
 }
 
 if (is_array($block['slider'])) {
 
 $html .= $this->getUrlLinks($block['slider']);
 }
 
 if (is_array($block['last'])) {
 $html .= $this->getUrlLinks($block['last']);
 }
 
 return $html;
 }

控制器中如何智能化设置呢？注意上面的：public $rollPage=1;//侧面显示个数

我们在控制器中的引用是这样的：
