LAMP中PHP功能 的动态扩展
php的动态扩展
我的php版本是php-5.4.6,现在在线跑着lamp,但是目前不支持gd扩展,不想重新编译安装,所以我想尝试一下给php来个动态扩展
第一步,需要执行phpize生成先关的编译包
[root@localhost src]# cd php-5.4.6/ext
里面有各种扩展,当然也有我要选的gd,既然我想装gd,为了避免出错先
[root@localhost ext]# yum install gd-devle -y
[root@localhost ext]# cd gd

[root@localhost gd]# phpize
[root@localhost gd]# ./configure && make && make install
在执行这一步的时候报错了
/usr/src/php-5.4.6/ext/gd/gd.c:1582: error: too many arguments to function ;zend_list_insert‘
解决这个问题vi /usr/src/php-5.4.6/ext/gd/gd.c
将zend_list_insert(font, le_gd_font TSRMLS_CC) 改为zend_list_insert(font, le_gd_font )然后保存,重新编译安装即可。
安装成功后会出现下面的语句
Installing shared extensions: /usr/local/lib/php/extensions/no-debug-zts-20090626/
第二步,修改php配置文件
编译完成后
[root@localhost gd]# cd modules/
[root@localhost modules]# ls
gd.so
生成一个gd.so的库文件,需要加到php.ini的扩展中,然后需要在/usr/local/lib/php.ini文件中加下面两行
vi /usr/loca/lib/php.ini
extension_dir="/usr/local/lib/php/extensions/no-debug-zts-20090626/"
extension=gd.so
第三步,重启apache服务即可

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.
