读取rrs的php
以前因为做学校论坛的需要,曾经写过一个读取shou论坛rrs的一段php,写出来以供大家参考
php
// 下面就是定义函数来提取数据:
// 处理开始标记的属性指
// $attrs是一个多维数组,键值为属性名, 值就是该属性的值
function startElement( $parser , $element_name , $attrs ){
global $temp , $current_tag ;
$current_tag = $element_name ;
switch ( $element_name ){
case ' ITEM ' :
echo '' ;
break ;
default :
break ;
}
}
// $current_tag告诉我们正在处理的标记,我们随后会在characterData函数中使用
function endElement( $parser , $element_name , $attrs ){
global $temp , $current_tag ;
switch ( $element_name ){
case ' ITEM ' :
return_page( $temp );
$temp = '' ;
break ;
default :
break ;
}
}
// 传送给此函数的是元素间的数据
// 例如,对
function characterData( $parser , $data ){
global $current_tag , $temp , $catID ;
switch ( $current_tag ){
case ' TITLE ' :
$temp [ ' title ' ] = $data ;
$current_tag = '' ;
break ;
case ' LINK ' :
$temp [ ' url ' ] = $data ;
$current_tag = '' ;
break ;
case ' AUTHOR ' :
$temp [ ' author ' ] = $data ;
$current_tag = '' ;
case ' DESCRIPTION ' :
$temp [ ' description ' ] = $data ;
$current_tag = '' ;
default :
break ;
}
}
?>
php
function return_page(){
global $temp ;
echo ' o ' . $temp [ ' title ' ] . '
' ;
}
// 分析的内容,即rrs的未知,可以是网络位置,也可以是文件
$xml_file = ' http://club.sohu.com/list-70th-0-0.xml ' ;
// 定义字符集,默认是UTF-8
//$type = 'UTF-8';
// 建立解析器
$xml_parser = xml_parser_create ();
// 设置解析选项
//xml_parser_set_option($xml_parser, XML_OPTION_CASE_FOLDING, true);
//xml_parser_set_option($xml_parser, XML_OPTION_TARGET_ENCODING, 'UTF-8');
// 告诉PHP发现元素时要调用什么函数
// 这些函数同时也处理元素的属性
xml_set_element_handler ( $xml_parser , ' startElement ' , ' endElement ' );
// 告诉PHP对字符数据调用什么函数
xml_set_character_data_handler ( $xml_parser , ' characterData ' );
if ( ! ( $fp = fopen ( $xml_file , ' r ' ))) {
die ( " 因网络问题,暂时无法获得数据,请稍候刷新再试 " );
}
// 通过循环来解析整个文件
while ( $data = fread ( $fp , 1024 ))
{
xml_parse ( $xml_parser , $data , feof ( $fp ));
}
fclose ( $fp );
xml_parser_free ( $xml_parser );
?>
另外可以加一段,用来预载网页的javascript的脚本

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 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.

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.

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.

RESTAPI design principles include resource definition, URI design, HTTP method usage, status code usage, version control, and HATEOAS. 1. Resources should be represented by nouns and maintained at a hierarchy. 2. HTTP methods should conform to their semantics, such as GET is used to obtain resources. 3. The status code should be used correctly, such as 404 means that the resource does not exist. 4. Version control can be implemented through URI or header. 5. HATEOAS boots client operations through links in response.

In PHP, exception handling is achieved through the try, catch, finally, and throw keywords. 1) The try block surrounds the code that may throw exceptions; 2) The catch block handles exceptions; 3) Finally block ensures that the code is always executed; 4) throw is used to manually throw exceptions. These mechanisms help improve the robustness and maintainability of your code.

The main function of anonymous classes in PHP is to create one-time objects. 1. Anonymous classes allow classes without names to be directly defined in the code, which is suitable for temporary requirements. 2. They can inherit classes or implement interfaces to increase flexibility. 3. Pay attention to performance and code readability when using it, and avoid repeatedly defining the same anonymous classes.
