Linux下独立添加PHP扩展模块mbstring
环境php5.2.13, 不支持mbstring扩展
假如php的源码包在/usr/local/src/php-5.2.13
php安装目录是/usr/local/php
# cd /usr/local/src/php-5.2.13/ext/mbstring/
# rpm -qa|egrep "autoconf|gcc" 这个是检测这些组件是否安装,没有安装请执行下面这句,否则会报错
# yum -y install autoconf gcc gcc-c++
# phpize
# ./configure --with-php-config=/usr/local/bin/php-config
# make
# make install
执行完毕后在php.ini里增加extension=mbstring.so
重启web服务器, 看一下phpinfo, 应该支持mbstring了!
1.安装crul
wget http://curl.haxx.se/download/curl-7.19.6.tar.gz
tar -zxvf curl-7.19.6.tar.gz
cd curl-7.19.6
./configure --prefix=/usr/local/curl
make
make install
2.编译生成扩展
进入php源程序目录中的ext目录中,这里存放着各个扩展模块的源代码,选择你需要的模块,比如curl模块:
cd curl
执行phpize生成编译文件,phpize在PHP安装目录的bin目录下
/usr/local/php5/bin/phpize
运行时,可能会报错:Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONF
environment variable is set correctly and then rerun this script.,需要安装autoconf:
yum install autoconf(RedHat或者CentOS)、apt-get install autoconf(Ubuntu Linux)
生成配置文件,并编译生成模块:
/usr/local/php5/bin/phpize
./configure --with-curl=/usr/local/curl --with-php-config=/usr/local/php5/bin/php-config
make
make install
生成的文件在(如:/usr/local/php5/extensions/no-debug-non-zts-20090626/)
这样,curl.so就被复制到PHP对应目录(如:/usr/local/php5/extensions/)
3.修改配置
在php.ini里,设置扩展目录:
extension_dir = "/usr/local/php5/extensions/"
并添加扩展模块引用:
extension = curl.so
4.检查并重启Apache
/usr/local/php5/bin/php -v
执行这个命令时,php会去检查配置文件是否正确,如果有配置错误,这里会报错,可以根据错误信息去排查

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.

VS Code system requirements: Operating system: Windows 10 and above, macOS 10.12 and above, Linux distribution processor: minimum 1.6 GHz, recommended 2.0 GHz and above memory: minimum 512 MB, recommended 4 GB and above storage space: minimum 250 MB, recommended 1 GB and above other requirements: stable network connection, Xorg/Wayland (Linux)

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.

The reasons for the installation of VS Code extensions may be: network instability, insufficient permissions, system compatibility issues, VS Code version is too old, antivirus software or firewall interference. By checking network connections, permissions, log files, updating VS Code, disabling security software, and restarting VS Code or computers, you can gradually troubleshoot and resolve issues.

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.

VS Code is available on Mac. It has powerful extensions, Git integration, terminal and debugger, and also offers a wealth of setup options. However, for particularly large projects or highly professional development, VS Code may have performance or functional limitations.
