下面要提供了是一款常用的php 常用分页代码哦，功能全面。

function multi($total, $perPage, $curPage, $pageUrl, $maxPages = 0, $page = 10, $autoGoTo = TRUE, $simple = FALSE) {
 $multiPage = '';
 $pageUrl .= strpos($pageUrl, '?') ? '&amp;' : '?';
 $realPages = 1;
 if($total > $perPage) {
  $offset = 2;

  $realPages = @ceil($total / $perPage);
  $pages = $maxPages && $maxPages < $realPages ? $maxPages : $realPages;

  if($page > $pages) {
   $from = 1;
   $to = $pages;
  } else {
   $from = $curPage - $offset;
   $to = $from + $page - 1;
   if($from < 1) {
    $to = $curPage + 1 - $from;
    $from = 1;
    if($to - $from < $page) {
     $to = $page;
    }
   } elseif ($to > $pages) {
    $from = $pages - $page + 1;
    $to = $pages;
   }
  }

  $multiPage = ($curPage - $offset > 1 && $pages > $page ? '<a href="'.$pageUrl.'page=1" class="first"'.$ajaxtarget.'>1 ...</a>' : '').
   ($curPage > 1 && !$simple ? '<a href="'.$pageUrl.'page='.($curPage - 1).'" class="prev"'.$ajaxtarget.'>&lsaquo;&lsaquo;</a>' : '');
  for($i = $from; $i <= $to; $i++) {
   $multiPage .= $i == $curPage ? '<strong>'.$i.'</strong>' :
    '<a href="'.$pageUrl.'page='.$i.($ajaxtarget && $i == $pages && $autoGoTo ? '#' : '').'"'.$ajaxtarget.'>'.$i.'</a>';
  }

}

function dhtmlspecialchars($string) {

  }
 } else {
