本文實例講述了PHP動態柱狀圖實現方法。分享給大家供大家參考。具體分析如下:
1.需求
查詢最近一個月的數據總條數和審核通過的條數,做成柱狀圖
2.實現代碼:
<!DOCTYPE html> <?php //計算上一個月的今天 function last_month_today($time){ $last_month_time = mktime(date("G", $time), date("i", $time),date("s", $time), date("n", $time), 0, date("Y",$time)); $last_month_t = date("t", $last_month_time); if ($last_month_t < date("j", $time)) { return date("Y-m-t H:i:s", $last_month_time); } return date(date("Y-m", $last_month_time) . "-d", $time); } ?> <?php include dirname(dirname(dirname(__FILE__))).'/config.php'; $endDate = date('Y-m-d'); $date = strtotime($endDate); $beginDate= last_month_today($date); //查詢最近一個月的總的數據條數 $sql = 'select count(*) from newpro where p_date>\''.$beginDate.'\' and p_date<\''.$endDate.'\''; //$sql = "select count(*) from newpro where p_date>'$beginDate' and p_date <'$endDate'";//這條語句也可以 $d = db()->query($sql)->fetch(PDO::FETCH_NUM); //echo "總的數據條數:".$d[0]; //查詢審核通過的數據條數 $sql2=$sql.' and is_pa_check_first=1 and is_pa_check_second=1 and is_pa_check_third=1'; $d2 = db()->query($sql2)->fetch(PDO::FETCH_NUM); //echo "審核通過的數據條數:".$d2[0]; //查詢一次審核通過的條數 $sql3=$sql.' and is_pa_check_first=1'; $d3 = db()->query($sql3)->fetch(PDO::FETCH_NUM); //查詢二次審核通過的條數 $sql4=$sql.' and is_pa_check_first=1 and is_pa_check_second=1'; $d4 = db()->query($sql4)->fetch(PDO::FETCH_NUM); ?> <html> <head> <meta charset="utf-8"/> <style> table{ cellpadding:0px; cellspacing:0px; } p{ padding:0px; margin:0px; } div{ background-color:#669900; width:50px; } #div1{ height:200px; } </style> <script type="text/javascript" src="../../../js/jquery-1.7.2.min.js"></script> </head> <body> <table border="0" > <tr align="center" valign="bottom"> <td> <p><?php echo $d[0]?></p> <div id="div1"></div> </td> <td > <p><?php echo $d3[0]?></p> <div style="height:<?php $str=floor(($d3[0]/$d[0])*200); echo $str.'px'?>"></div> </td> <td > <p><?php echo $d4[0]?></p> <div style="height:<?php $str=floor(($d4[0]/$d[0])*200); echo $str.'px'?>"></div> </td> <td > <p><?php echo $d2[0]?></p> <div style="height:<?php $str=floor(($d2[0]/$d[0])*200); echo $str.'px'?>"></div> </td> </tr> <tr align="center" valign="top"> <td><p>總計</p></td> <td><p>一審通過</p></td> <td><p>二審通過</p></td> <td><p>審核通過</p></td> </tr> </table> </body> </html>
3.效果圖如下所示:
希望本文所述對大家的php程序設計有所幫助。
