The example in this article describes the PHP dynamic histogram implementation method. Share it with everyone for your reference. The specific analysis is as follows:
1. Demand
Query the total number of data items and the number of approved items in the last month, and make a histogram
2. Implementation code:
<!DOCTYPE html> <?php //计算上一个月的今天 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); //查询最近一个月的总的数据条数 $sql = 'select count(*) from newpro where p_date>\''.$beginDate.'\' and p_date<\''.$endDate.'\''; //$sql = "select count(*) from newpro where p_date>'$beginDate' and p_date <'$endDate'";//这条语句也可以 $d = db()->query($sql)->fetch(PDO::FETCH_NUM); //echo "总的数据条数:".$d[0]; //查询审核通过的数据条数 $sql2=$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 "审核通过的数据条数:".$d2[0]; //查询一次审核通过的条数 $sql3=$sql.' and is_pa_check_first=1'; $d3 = db()->query($sql3)->fetch(PDO::FETCH_NUM); //查询二次审核通过的条数 $sql4=$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>总计</p></td> <td><p>一审通过</p></td> <td><p>二审通过</p></td> <td><p>审核通过</p></td> </tr> </table> </body> </html>

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
