一直想规范自己的php代码,终于实现鸟~
0.编码统一使用utf-8
1.缩进:严格缩进,4个空格(Tab)
2.花括号:if语句下方的语句块,无论多少行,统一加花括号。
3.模版:
①
示例1
<!-- <?php print <<<EOT --> <center><br> [ <a href='$db_ceoconnect'>联系我们</a> - <a href='$db_wwwurl'>网站导航</a> ]<br>$db_union[1]<br> <span style="font-size: 11px; font-family: Tahoma, Arial;color: #000000;">Powered by <a href="http://www.ofstar.net" style="color: #000000" target="_blank"><b>Ofstar</b> <b style="color:#FF9900">$ofstar_version</b></a> Copyright © 2003-05 <a href="http://www.ofstar.net" target="_blank" style="color: #000000">Ofstar Team</a><br>$ofstar_spend $ft_gzip</span> </center></body></html> <!-- EOT; ?>-->
示例2
foreach($forumdb as $forum) {if($forum[type]==forum){print <<<EOT <!--版块模版--> <tr height=41> <td width=5% align=center valign=middle class='f_two'><img src='$imgpath/$stylepath/$forum[pic].gif' border=0 alt="php代码规范" ></td> <td width=53% class='f_one' align=left onMouseOver="this.className='f_two'" onMouseOut="this.className='f_one'"><a href='thread.php?fid=$forum[fid]'>$forum[logo]</a> <a href='thread.php?fid=$forum[fid]' class=fnamecolor><b>$forum[name]</b></a><br><span class=smalltxt>$forum[info]</span></td> <td width=7% class='f_two' align=center>$forum[tpc]</td> <td width=7% class='f_one' align=center>$forum[atc]</td> <td class=smalltxt align=center title='$forum[newtitle]' width=16% bgcolor=$forumcolortwo>$forum[newpost]</td> <td width=12% class='f_one' align=center style="max-width:90%">$forum[admin]</td> </tr> <!-- EOT; }
②统一保存为.htm文件。通过PrintEot函数调用
function PrintEot($template,$EXT="htm") { global $tplpath; SafePath($template); if(empty($template)) $template='N'; $path="./template/$template.$EXT"; return $path; } function SafePath($Path){ if(strpos($Path,'..')!==false){ showmsg('非法操作,请返回.....'); } } include PrintEot('login');
4.数据库操作:
①连接
$sqlhost = "localhost"; //数据库地址 $sqlname = ""; //数据库名称 $usename = ""; //数据库用户名 $password = ""; //数据库密码 $conn = @mysql_connect("$sqlhost","$usename","$password"); $conn_b = @mysql_select_db("$sqlname"); if(!$conn) { echo "数据库链接失败,请检查帐号或密码是否正确!"; die; } if(!$conn_b) { echo "数据库打开失败,请检查数据库名称是否正确!"; die; } mysql_query("set names utf8");
保存为conn.php
②读写数据库
global $conn; //全局变量 $sql = "select StaffID, Name, LoginName from Staff"; //sql语句统一放入$sql变量 $query = mysql_query($sql,$conn); //查询sql统一使用mysql_query函数,结果放入$query变量中 $list = array(); while($row = @mysql_fetch_array($query)) //查询结果统一使用mysql_fetch_array函数分割,同时在函数前添加@号防止输出错误信息,结果放入$row变量中 { $list[] = $row; }
5.文件、文件夹命名规范:
①文件夹
图片:images
php源文件:source
模板:template
②文件:
按模块命名:模块_功能,例如 admin_editstaff.php
唉~要大改自己曾经的一个项目了。。

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

The reasons why PHP is the preferred technology stack for many websites include its ease of use, strong community support, and widespread use. 1) Easy to learn and use, suitable for beginners. 2) Have a huge developer community and rich resources. 3) Widely used in WordPress, Drupal and other platforms. 4) Integrate tightly with web servers to simplify development deployment.

PHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.
