Php的配置参数有很多,这里只做一些常用参数的说明。
首先下载php源码包http://www.php.net
当然了在安装之前,你需要安装很多依赖包,否则安装过程会出错,可能还需要单独编译安装一些源码包,具体可根据实际情况而定。此处只针对php的常用参数做说明,其他不做解释。
通过./configure --help |less查看其相关参数,确实有太多了。
php编译安装
./configure \
--prefix=/usr/local/php5 \【指定php的安装路径】
--with-gd \【启用gd库的支持】
--with-zlib \【启用zlib库】
--with-mysql=/usr/local/mysql/ \【指定mysql的安装位置,适用于集成环境,如果数据分离,则无需表明路径,启用mysql即可】
--with-config-file-path=/usr/local/php5【指定php.ini文件的位置】
--enable-mbstring \【启用多字节、字符串支持】
--enable-fpm \【启用ftp模块,cgi方式安装】
--with-mysql-sock=/tmp/mysqld.sock \【指定mysql sock文件位置】
--with-mysqli=/usr/local/mysql/bin/mysql_config【mysqli文件目录】
--with-iconv \【启用iconv函数各种字符集之间的转换】
--enable-xml \【启用xml支持】
--enable-bcmath \【打开图片大小调整,这个貌似zabbix监控的时候会用到】
--enable-shmop \【启用shmop支持,此模块是一个易于使用的功能集,允许php读,写,创建和删除UNIX共享内存段】
--enable-sysvsem \【共享内存插件和shmop配合使用】
--enable-mbregex \【启用正则】
--enable-ftp \【启用ftp支持】
--enable-gd-native-ttf \【支持TrueType字符串函数库】
--with-openssl \【启用openssl的支持,这对于安全传输有很好的作用】
--enable-pcntl \【freeTDS需要用到】
--enable-sockets \【启用sockets支持模块】
--with-xmlrpc \【启用xml-rpc的c语言支持】
--enable-soap \【soap简单对象访问协议是交换数据的一种协议规范,是一种对象访问协议,大致分为四个部分,封装-编码规则-rpc表示-绑定】
--enable-session \【启用session会话选项,使用非常广泛】
--with-gettext \【开启GNU的gettext支持,编码库用的到】
--with-jpeg-dir
--with-freetype-dir \【启用对freetype的支持,可以google一下看看这个模块的具体含义】
--enable-zip \【启用zip压缩】
--enable-sysvmsg \【启用消息队列模块】
--enable-sysvshm \【启用系统v信号支持】
--with-pdo-mysql=/usr/local/mysql/【启用pdo的mysql扩展,对php的版本有要求,php5以上,pdo扩展本身并不能执行任何数据库操作,必须使用一个pdo驱动来访问数据库】
然后
make && make install
――――――――――――――――――――――――――――――――――――――――――――
php还有很多模块,比如memcache,redis,zend,等等。相对来说,php5以上版本开启了灵活的安装方式,有些模块,即使你没有安装也没关系,等需要的时候再安装也可以,基本上无需重新编译就可以安装扩展模块。

对于安装完成之后,可以通过php的info函数来产看当前php安装的所有功能。也可以通过命令查看

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.
