在使用laravel分页时候，默认的分页样式不是自己想要的，需要自己修改。

默认样式是 < 1 2 3 4 5 6 7 8 9 10 11 12 13 14 ... 98 99 >

这个样式太丑了，而且我不想要这么多的 页码，只想实现如下的页码

< 1 2 3 4 5 6 7 >     < 6 7 8 9 10 11 >      < 11 12 13 14 15 16 17 18 19 20 >

php原生代码

<?php 
//分页显示页面数量,取值范围 3-n
$paging_number = 7;
if($paging_number<3){
	$paging_number = 3;
}
//当前页
$paging_current_page = $_GET['p'];
//共几页
$paging_last_page = 15;

if(($paging_number%2) == 0){
	if($paging_last_page <= $paging_number){
		$paging_start = 1;
		$paging_end = $paging_last_page;
	}else if($paging_current_page < ($paging_number/2+1)){
		$paging_start = 1;
		$paging_end = $paging_number;
	}else if($paging_current_page >= ($paging_number/2+1) && (($paging_current_page + ($paging_number/2 - 1)) <= $paging_last_page)){
		$paging_start = $paging_current_page - ($paging_number/2);
		$paging_end = $paging_current_page + ($paging_number/2 - 1);
	}else{
		$paging_start = $paging_last_page - $paging_number + 1;
		$paging_end = $paging_last_page;
	}
}else{
	if($paging_last_page <= $paging_number){
		$paging_start = 1;

	}else if($paging_current_page < ceil($paging_number/2)){
		$paging_start = 1;
		$paging_end = $paging_number;
	}else if($paging_current_page >= ceil($paging_number/2) && (($paging_current_page + floor($paging_number/2)) <= $paging_last_page)){

	}else{

	}
}
