php和swf通信

Jun 23, 2016 pm 02:32 PM

SWF和PHP通信(LoadVars类的sendAndLoad方法存,解析XML的方式取):
SWF←PHP:PHP用echo写xml文件,SWF直接解析该文件。(我以前纳闷为什么蓝色的RSS是PHP格式的,学到这里才明白。)
  SWF→PHP:swf用“sendAndLoad”(data_lv.uname="张三")发送变量,php用$name=$_POST['uname']接收变量。

  注:
  1、留言本其实就是这两个小的过程,PHP相当于一个桥梁。强烈建议将2和3都写出一个简单的例子,例子运行成功了,留言本没开始写就已经完成一大半了。
  2、sendAndLoad既可以发送变量给php,也可以接收php的变量(类似于swf读取文本)。可以看火山的教程,很详细。

  开始制作(做好上面的准备工作,下面的会很好理解):

图1
1、SWF读取数据
  ①和②MySQl→PHP→SWF
  PHP用“SELECT”从MySQl那里取,再写成xml给SWF读。

图2
 2、SWF储存数据
  ③和④SWF→PHP→MySQl
  SWF用“sendAndLoad”给PHP,PHP用“INSERT”给MySQl。

图3
 解决乱码(解决数据库中的中文读出来是"????"):
  在用PhpAdmin建立数据库的时候选择“utf8-geeral-ci”编码。
  在php文件的查询语句前,加上:mysql_query("set names 'utf8'");
  php模块化(便于以后修改):
  连接数据库的语句写在单独的文件中,如connectdb.php。
  则写数据(datatosql.php)和读数据(datatoxml.php)的文件中加上:require "connectdb.php"即可。
  MySQL排错函数(如操作有错,根据提示会很方便修改):
  mysql_errno(出错号); mysql_error(出错原因)。
  php的日期函数(更详细的可参考其他帮助):
  data("Ymd,l,H:i"); //20080608,Sunday,09:28
  SWF实时刷新(保证读取最新数据):
  swf发送并获取实时变量:data_lv.sendAndLoad("datatosql.php?n="+random(9999), data_lv, "post");
  swf读取实时xml:myXML.load("datatoxml.php?n="+random(9999))

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. 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? 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.

What are Enumerations (Enums) in PHP 8.1? What are Enumerations (Enums) in PHP 8.1? Apr 03, 2025 am 12:05 AM

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

Describe the SOLID principles and how they apply to PHP development. 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.
