PHP简单分页的实现

程序的关键点是页码的获取

";    $url=$_SERVER["PHP_SELF"];    $pageNow =isset($_GET['pageNow'])?$_GET['pageNow']:1;    $start=($pageNow-1)*$every;    $allsql = "select * from {$table};";    // die();    // $sql = "select * from test;";    $rest = $conn->query($allsql);    $field = $rest->fetch_fields();    $fieldNum = count($field);   //字段数量    //获取数据量    $rowNum = $rest->num_rows;    // echo "记录条数:".$rowNum;    $allpage=ceil($rowNum/$every);    // echo "----每页分$every"."条时有$allpage"."页
";    // $pageNow=($pageNow-1)*$every;    echo "

"; // echo "

测试信息表 添加

"; // echo "

$pageNow"."页

"; echo ""; for ($i=0; $i ".$field[$i]->name.""; } echo ""; //显示分页 $sql="select * from $table limit $start,$every;"; // echo $sql; $newRest = $conn->query($sql); while($row = $newRest->fetch_row()){ echo ""; for ($j=0; $j ".$row[$j].""; } echo ""; } echo ""; echo "

"; echo "

"; echo "$pageNow/$allpage"; echo "首页"; if($pageNow==1){ echo "上一页"; }else{ $pagePre=$pageNow-1; echo "上一页"; } // echo "上一页"; // echo "下一页"; if($pageNow==$allpage){ echo "下一页"; }else{ $pageNext=$pageNow+1; // echo "

$pageNow

"; echo "下一页"; } echo "尾页"; echo "

"; echo ""; echo "选择分页"; for($i=1;$i$i"; } echo ""; echo "

"; echo "

";$conn->close();}//实际使用一个测试数据表echo pagef(10,'test');?>
