大神来帮忙啊!怎么把这两段代码的功能结合起来啊,试了一天了。
情况是要做一个页面,输出数据库的销售记录,卖出3件以上的显示绿色,3件以下白色。
这个功能已经实现了,代码:
<?php$conn = mysql_connect('127.0.0.1:8889', 'root', 'root');mysql_select_db('chanping', $conn);$sql="select * from xiaoshou";$r = mysql_query($sql);?> <?php while($rs = mysql_fetch_assoc($r)) { if($rs["count"] >= "3") { echo ("<tr bgcolor=green>"); }else{ echo ("<tr bgcolor=white>"); }?> <tr> <td><?php echo $rs["xinghao"];?></td><td><?php echo $rs["count"];?></td> </tr> <?php } echo ("</table>");?>
这个是每条记录为一行,垂直显示的。
在这个基础上,希望HTML页面以每3段完整记录(型号和count)为一行历遍下去,网上找了段代码如下:
<?php $a = array (1,2,3,4,5,6,7,8,9,10,11); $i = 0; ?> <table border=1> <tr> <? foreach ($a as $k){ if($i%3==0) {//该处表示需要横向排列的列数. echo "</tr><tr>"; } echo "<td>",$k,"</td>";//该处显示该列的数据. $i ++; } ?>
这两段代码怎么结合起来啊?
能让网页按如下显示
xinghao1 count xinghao2 count xinghao3 count
xinghao4 count xinghao5 count xinghao6 count
xinghao7 count xinghao8 count xinghao9 count
试了很多都不成功 ,求大神帮助!不胜感激!

<?php$conn = mysql_connect('127.0.0.1:8889', 'root', 'root');mysql_select_db('chanping', $conn);$sql="select * from xiaoshou";$r = mysql_query($sql);?><table><?php$index = 1;while($rs = mysql_fetch_assoc($r)){ if($index%3==1) echo('<tr>'); if($rs["count"] >= "3") { echo ("<td bgcolor=green>"); }else{ echo ("<td bgcolor=white>"); }?> <?php echo $rs["xinghao"];?></td><td><?php echo $rs["count"];?></td><?php if($index%3==0) echo('</tr>'); $index++;}--$indexif($index%3!=0) echo('</tr>');?></table>
代码没试过,思路应该是这样
那每行颜色不用区分了?

哥 上次帮助真是太感谢了 !还是要区分的 我就是不明白为什么把数据库表的列放入数据里为什么运行不出来? 麻烦再帮我看下!谢谢

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,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
