1、连接MYSQL数据库代码 <?php $connec=mysql_connect("localhost","root","root") or die("不能连接数据库服务器: ".mysql_error()); mysql_select_db("liuyanben",$connec) or die ("不能选择数据库: ".mysql_error()); mysql_query("set names 'gbk'"); ?>
2、读取数据库,并实现循环输出 <?php $sql="select * from liuyan order by ly_id desc"; $conn=mysql_query($sql,$connec); while($rs=mysql_fetch_array($conn)){ ?> 循环的内容......... <?php } ?>
3、如何实现分页,包括两个函数,两个调用 1)两个函数 <? //分页函数 function genpage(&$sql,$page_size=2) { global $prepage,$nextpage,$pages,$sums; //out param $page = $_GET["page"]; $eachpage = $page_size; $pagesql = strstr($sql," from "); $pagesql = "select count(*) as ids ".$pagesql; $conn = mysql_query($pagesql) or die(mysql_error()); if($rs = mysql_fetch_array($conn)) $sums = $rs[0]; $pages = ceil(($sums-0.5)/$eachpage)-1; $pages = $pages>=0?$pages:0; $prepage = ($page>0)?$page-1:0; $nextpage = ($page<$pages)?$page+1:$pages; $startpos = $page*$eachpage; $sql .=" limit $startpos,$eachpage "; } // 显示分页 function showpage() { global $page,$pages,$prepage,$nextpage,$queryString; //param from genpage function $shownum =10/2; $startpage = ($page>=$shownum)?$page-$shownum:0; $endpage = ($page+$shownum<=$pages)?$page+$shownum:$pages;
32.节日倒计时 <Script Language="JavaScript"> var timedate= new Date("October 1,2002"); var times= "国庆节"; var now = new Date(); var date = timedate.getTime() - now.getTime(); var time = Math.floor(date / (1000 * 60 * 60 * 24)); if (time >= 0) document.write( "现在离"+times+"还有: "+time +"天") </Script>
33.打开窗口即最大化 <script language="JavaScript"> <!-- Begin self.moveTo(0,0) self.resizeTo(screen.availWidth,screen.availHeight) // End --> </script>
