php开发之表单的插入和获取
1，表单的插入
表单的插入操作步骤如下：
a,在html的body>…/body>标记中添加一个表单
b,在表单中添加表单元素
具体示例代码如下：
<form name ="form1" method = "post" enctype ="multipart/form-data" action ="index.php"> <table width ="405" border ="1" cellpading ="1" cellspacing ="1" bordercolor ="#FFFFFF" bgcolor ="#999999"> <tr bgcolor ="FFCC33"> <td width ="103" height ="25" align ="right"> 姓名：</td> <td width ="144" height ="25"> <input name ="user" type ="text" id ="user" size ="20" maxlength ="100"> </td> </tr> <tr bgcolor ="#FFCC33"> <td width ="103" height ="25" align ="right">性别：</td> <td height ="25" colspan ="2" align ="left"> <input name ="sex" type ="radio" value ="男" checked>男 <input name ="sex" type ="radio" value ="女">女 </td> </tr> <tr bgcolor ="#FFCC33"> <td width ="103" height ="25" align ="right">密码：</td> <td width ="289" height ="25" colspan ="2" align ="left"> <input name ="pwd" type ="password" id ="pwd" size ="20" maxlength ="100"> </td> </tr> <tr bgcolor ="#FFCC33"> <td height = "25" align ="right">爱好：</td> <td height ="25" colspan ="2" align ="left"> <input name ="fond[]" type ="checkbox" id = "fond[]" value ="音乐">音乐 <input name ="fond[]" type ="checkbox" id ="fond[]" value ="其他">其他 </td> </tr> <tr bgcolor ="#FFCC33"> <td height ="25" align ="right">写真</td> <td height ="25" colspan ="2"> <input name ="phpto" type ="file" size ="20" maxlength ="1000" id ="photo"> </td> </tr> <tr bgcolor ="#FFCC33"> <td height ="25" align ="right">个人简介：</td> <td height ="25" colspan ="2"> <textarea name ="intro" cols ="28" rows ="4" id ="intro"></textarea> </td> </tr> <tr bgcolor ="#FFCC33"> <td height ="25" colspan ="3"> <input name ="submit" type ="submit" value ="提交"> <input name ="submit2" type ="reset" value ="重置"> </td> </tr> </table></form>
运行结果如下：
2，表单的获取
(1) 使用POST方法提交表单
应用POST方法时，只需要将<form>中表单的method属性设置为POST即可。
示例代码如下：
user.html文件代码如下：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml" lang="en_US" xml:lang="en_US"><!-- * Created on 2015年3月24日 * * To change the template for this generated file go to * Window - Preferences - PHPeclipse - PHP - Code Templates --> <head> <title> </title> </head> <body> <form name ="form1" method ="post" enctype ="multipart/form-data" action ="index.php"> <table width ="300" border ="0" cellpading ="0" cellspacing ="0"> <tr> <td height ="30" align ="right">姓名：</td> <td height ="30"> <input name ="userName" type ="text" size ="20"> <input name ="submit" type ="submit" value ="提交"> </td> </tr> </table></form> </body></html>
index.php的代码如下：
<?php include("user.html"); $userName =$_POST["userName"]; echo $userName; ?>运行结果如下：
可以看到表单上的数据已经通过post方法传递给了服务器。
(2)使用GET方法提交表单
GET方法是提交表单方法的默认方法，使用GET提交的参数会附加到url地址的后面，具体格式如下：
在这里user.html文件还是用上面的，把form的method属性改为get就好了。
index.php的代码如下：
<?php include("user.html"); $userName =$_GET["userName"]; echo $userName; ?>运行结果如下：
可以看到参数已经被附加到url的后面了。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
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,
How does session hijacking work and how can you mitigate it in PHP?
Apr 06, 2025 am 12:02 AM
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.
Describe the SOLID principles and how they apply to PHP development.
Apr 03, 2025 am 12:04 AM
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.

Explain late static binding in PHP (static::).
Apr 03, 2025 am 12:04 AM
Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
