CI默认的rewrite url中是类似这样的,例如你的CI根目录是在/CodeIgniter/下,你的下面的二级url就类似这样http://localhost/CodeIgniter/index.php/welcome。不太好看,怎么把其中的index.php取掉呢?
1. 打开apache的配置文件,conf/httpd.conf :
LoadModule rewrite_module modules/mod_rewrite.so,把该行前的#去掉。
搜索 AllowOverride None(配置文件中有多处),看注释信息,将相关.htaccess的该行信息改为AllowOverride All。
2. 在CI的根目录下,即在index.php,system的同级目录下,建立.htaccess,直接建立该文件名的不会成功,可以先建立记事本文件,另存为该名的文件即可。内容如下(CI手册上也有介绍):
RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]
如果文件不是在www的根目录下,例如我的是:http://www.nowamagic.net/CodeIgniter/,第三行需要改写为RewriteRule ^(.*)$ /CodeIgniter/index.php/$1 [L]。
另外,我的index.php的同级目录下还有js文件夹和css文件夹,这些需要过滤除去,第二行需要改写为:RewriteCond $1 !^(index\.php|images|js|css|robots\.txt)
3.将CI中配置文件(system/application/config/config.php)中$config['index_page'] = "index.php";将$config['index_page'] = ""; 。
/*
|--------------------------------------------------------------------------
| Index File
|--------------------------------------------------------------------------
| Typically this will be your index.php file, unless you've renamed it to
| something else. If you are using mod_rewrite to remove the page set this
| variable so that it is blank.
*/
$config['index_page'] = '';

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.
