因为要做某项目的一个新功能,而这个新功能又是用公司新开发的框架做的。
该框架甚是NB啊,NB到什么地方那。主要有一下几点:
1、该框架无文档;
2、该框架源码中无注释;
3、除了那帮主线开发人员我们部门很少有人熟悉使用;
如果想使用这个框架做东西,只有一条路:看源码,先了解框架的实现原理,然后再用这个鸟玩意做东西。
当我看到一个处理request的类的时候,如下代码映入眼帘:
<p class="sycode"> 1 static function get_base_url(){ 2 $filename = ( isset ( $_SERVER [ ' SCRIPT_FILENAME ' ])) ? basename ( $_SERVER [ ' SCRIPT_FILENAME ' ]) : '' ; 3 if ( isset ( $_SERVER [ ' ORIG_SCRIPT_NAME ' ]) && basename ( $_SERVER [ ' ORIG_SCRIPT_NAME ' ]) === $filename ) { 4 $base_url = $_SERVER [ ' ORIG_SCRIPT_NAME ' ]; 5 } elseif ( isset ( $_SERVER [ ' SCRIPT_NAME ' ]) && basename ( $_SERVER [ ' SCRIPT_NAME ' ]) === $filename ) { 6 $base_url = $_SERVER [ ' SCRIPT_NAME ' ]; 7 } elseif ( isset ( $_SERVER [ ' PHP_SELF ' ]) && basename ( $_SERVER [ ' PHP_SELF ' ]) === $filename ) { 8 $base_url = $_SERVER [ ' PHP_SELF ' ]; 9 } else { 10 $path = isset ( $_SERVER [ ' PHP_SELF ' ]) ? $_SERVER [ ' PHP_SELF ' ] : '' ; 11 $file = isset ( $_SERVER [ ' SCRIPT_FILENAME ' ]) ? $_SERVER [ ' SCRIPT_FILENAME ' ] : '' ; 12 $segs = explode ( ' / ' , trim ( $file , ' / ' )); 13 $segs = array_reverse ( $segs ); 14 $index = 0 ; 15 $last = count ( $segs ); 16 $base_url = '' ; 17 do { 18 $seg = $segs [ $index ]; 19 $base_url = ' / ' . $seg . $base_url ; 20 ++ $index ; 21 } while (( $last > $index ) && ( false !== ( $pos = strpos ( $path , $base_url ))) && ( 0 != $pos )); 22 } 23 24 $request_uri = self :: get_request_uri(); 25 if ( 0 === strpos ( $request_uri , $base_url )) { 26 return self :: dirname ( $base_url ); 27 } 28 if ( 0 === strpos ( $request_uri , dirname ( $base_url ))) { 29 return self :: dirname ( $base_url ); 30 } 31 32 $truncatedrequest_uri = $request_uri ; 33 if (( $pos = strpos ( $request_uri , ' ? ' )) !== false ) { 34 $truncatedrequest_uri = substr ( $request_uri , 0 , $pos ); 35 } 36 37 $basename = basename ( $base_url ); 38 if ( empty ( $basename ) || ! strpos ( $truncatedrequest_uri , $basename )) { 39 return ; 40 } 41 42 if (( strlen ( $request_uri ) >= strlen ( $base_url )) 43 && (( false !== ( $pos = strpos ( $request_uri , $base_url ))) && ( $pos !== 0 ))) { 44 $base_url = substr ( $request_uri , 0 , $pos + strlen ( $base_url )); 45 } 46 return rtrim (self :: dirname ( $base_url ) , ' / ' ); 47 } </p>
要学的东西真是太多了,今天第一次看见$_SERVER['ORIG_SCRIPT_NAME']这个变量。做什么的?还真不清楚。
以前我只是知道$_SERVER['SCRIPT_NAME'']这个变量。
我一向是追根究底,有什么不清楚的,如果不弄出来,难受啊。
用度娘搜索了下,见下面这段话:
要知道PHP当前是通过CGI来运行,还是在Apache内部运行,可以检查一下环境变量orig_script_name。
如果PHP通过CGI来运行,这个变量的值就是/Php/Php.exe。
如果Apache将PHP脚本作为模块来运行,该变量的值应该是/Phptest.php
这才恍然大悟啊。原来是这个原因啊。
看样子,想把php学好,学精还要大下一番功夫啊。
仅此为记。

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
