PHP 长稿子分页 手动插入分页标签

<?php $contents = $rs['content'];
			function conpage($contents) {  
			$pagesss='#page#';  //设定分页标签  
			$a=strpos($contents,$pagesss);  
			if($a){  
			$con=explode($pagesss,$contents);  
			$cons=count($con);   
			@$p = ceil($_GET['p']);  
			if(!$p||$p<0) $p=1;  
			$url=$_SERVER["REQUEST_URI"];  
			$parse_url=parse_url($url);  
			$url_query=$parse_url["query"];  
			if($url_query){  
			$url_query=ereg_replace("(^|&)p=$p","",$url_query);  
			$url=str_replace($parse_url["query"],$url_query,$url);  
			if($url_query) $url.="&p"; else $url.="p";  
			}else {  
			$url.="?p";  
			}  
			if($cons<=1) return false;//只有一页时不显示分页  
			$pagenav="<div class=\"lyztpage\">";  
			for($i=1;$i'.$p.'';  
				}else{  
					$pagenav.="<a href="%24url=%24i">$i</a>";  
				}  
			}  
			$pagenav.="";  
			return $con[$p-1].$pagenav;  
			}else{  
			return $contents;  
			}
