一个php分页函数

<?php

if($page>1 && $p<=$page){
$firstPage = $p == 0 ? “<span>首页</span>” : (‘<a href=”‘.$baseUri.'”>首页</a>’);

$previousPages=”;
for ($i=max(array(0,$p-4));$i<$p;$i++){
$previousPages.='<a href=”‘.$baseUri. ‘&p=’ . $i . ‘”>’.($i+1).'</a>’;
}
$currentPage='<span>’ . ($p + 1) . ‘</span>’;
$nextPages=”;
for ($i=$p+1,$end=min(array($page,$p+5));$i<$end;$i++){
