Teach you step by step how to set up a php8 environment (with solutions to common problems)
This article is provided by the php8 tutorial column to give you a detailed introduction on how to build a php8 environment step by step. I hope it will be helpful to everyone.
1. Download
1. Download https://www.php.net/distributions/php-8.0.0.tar.gz locally and upload the file to /usr/local /src/
2. wget -P /usr/local/src/ https://www.php.net/distributions/php-8.0.0.tar.gz
2. Unzip, compile, install
1, decompress
> cd /usr/local/src/ > tar xzf php-8.0.0.tar.gz > cd php-8.0.0
2, configure compilation parameters, refer to https://www.php.net/manual/zh... to choose the options you need
./configure --prefix=/usr/local/php8 --with-config-file-path=/usr/local/php8/etc --with-fpm-user=www --with-fpm-group=www --with-curl --with-openssl --with-mysqli --with-pdo-mysql --with-iconv --with-mhash --with-zlib --enable-mbstring --enable-gd --enable-gd-jis-conv --enable-sockets --enable-fpm --enable- --enable-xml --enable-pdo --enable-cli --enable-pcntl --enable-soap --enable-opcache --enable-fileinfo --disable-rpath --enable-mysqlnd --with-zip --enable-simplexml --with-libxml --with-sqlite3 --with-pdo-sqlite --enable-phar --enable-tokenizer --enable-cgi
Problem 1:
configure: error: Package requirements (libxml-2.0 >= 2.9.0) were not met: Package 'libxml-2.0', required by 'virtual:world', not found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables LIBXML_CFLAGS and LIBXML_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details.
Problem 1 solved:
> yum install libxml2-devel
Problem 2:
configure: error: Package requirements (sqlite3 > 3.7.4) were not met:
Problem 2 solved:
> yum install sqlite-devel
Problem 3:
configure: error: Package requirements (libcurl >= 7.29.0) were not met:
Problem 3 solved:
> yum install libcurl-devel
Problem 4:
configure: error: Package requirements (libpng) were not met:
Problem 4 solved:
> yum install libpng libpng-devel
Problem 5:
configure: error: Package requirements (oniguruma) were not met:
Solution to problem 5:
> cd /usr/local/src/ > wget http://ftp.altlinux.org/pub/distributions/ALTLinux/Sisyphus/x86_64/RPMS.classic/liboniguruma5-6.9.6-alt1.x86_64.rpm -O liboniguruma5-6.9.6-alt1.x86_64.rpm > rpm -ivh liboniguruma5-6.9.6-alt1.x86_64.rpm > wget http://ftp.altlinux.org/pub/distributions/ALTLinux/Sisyphus/x86_64/RPMS.classic/liboniguruma-devel-6.9.6-alt1.x86_64.rpm -O liboniguruma-devel-6.9.6-alt1.x86_64.rpm > rpm liboniguruma-devel-6.9.6-alt1.x86_64.rpmcli
Problem 6:
configure: error: Package requirements (libzip >= 0.11 libzip != 1.3.1 libzip != 1.7.0) were not met:
Solution to problem 6:
> yum install libzip libzip-devel

3. Compile source code
> make -j2 # This compilation relies on the number of system CPU cores, which will improve performance to a certain extent. Generally, the number of cores should not exceed half.
4. Installation
make install
Installation successful

5. Add environment variables
> vim /etc/profile # 在文件末尾加入 # PATH=$PATH:/usr/local/php8/bin/ # export PATH # :wq 保存并退出 > source /etc/profile # 立刻生效配置 > php -v # 获得如下信息 php -v PHP 8.0.0 (cli) (built: Dec 15 2020 02:46:59) ( NTS ) Copyright (c) The PHP Group Zend Engine v4.0.0-dev, Copyright (c) Zend Technologies
6. Obtain default configuration
// 复制php.ini到编译配置参数指定的目录。php.ini在解压的源码目录里 > cp /usr/local/src/php-8.0.0/php.ini-production /usr/local/php8/etc/php.ini // 复制一份php-fpm的配置模版文件到同级目录 方便备份和修改 > cp /usr/local/php8/etc/php-fpm.conf.default /usr/local/php8/etc/php-fpm.conf // 复制一份php-fpm的扩展配置模板文件到同级目录 方便备份和修改 > cp /usr/local/php8/etc/php-fpm.d/www.conf.default /usr/local/php8/etc/php-fpm.d/www.conf // 复制开启自起脚本到系统启动自动加载脚本目录。fpm/init.d.php-fpm在解压的源码目录里 > cp /usr/local/src/php-8.0.0/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
7. Start automatically after booting
The setting command can be executed
> chmod +x /etc/init.d/php-fpm # 添加可执行权限
Check the self-starting script
> service php-fpm start # 检验服务启动 > service php-fpm stop # 检验服务关闭 // 均正常提示 > chkconfig php-fpm on # 设置开机自动执行php-fpm开机自启动脚本 > reboot # 重启,ssh重连 # 重启后 [root@54skyer ~]# netstat -ntlp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 1097/nginx: master tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1061/sshd tcp 0 0 0.0.0.0:16379 0.0.0.0:* LISTEN 1090/redis-server 0 tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 1083/php-fpm: maste
7. Additional instructions
Some instructions about the configuration file
php-fpm.conf is unique to PHP-FPM Configuration file
php.ini is a necessary configuration file in all php modes
The difference between the two is that php-fpm.conf is the configuration file of the PHP-FPM process manager, php. ini is the configuration file of the PHP parser
Some PHP versions also have the /fpm.d/www.conf configuration file in the configuration file path
This is configured by php-fpm.conf File extension file, you can open the php-fpm.conf file to view
; include=fpm.d/*.conf
We can use php-fpm.conf to configure the slow log
We can enable the slow log function.
slowlog = /usr/local/var/log/php-fpm.log.slow request_slowlog_timeout = 5s

The differences between php5 and php8 are in terms of performance, language structure, type system, error handling, asynchronous programming, standard library functions and security. Detailed introduction: 1. Performance improvement. Compared with PHP5, PHP8 has a huge improvement in performance. PHP8 introduces a JIT compiler, which can compile and optimize some high-frequency execution codes, thereby improving the running speed; 2. Improved language structure, PHP8 introduces some new language structures and functions. PHP8 supports named parameters, allowing developers to pass parameter names instead of parameter order, etc.

The steps to add mysql extension to php8 are: 1. Install the MySQL client library; 2. Install the development tools for PHP 8; 3. Download the MySQL extension source code; 4. Compile and install the MySQL extension; 5. Enable the MySQL extension; 6. Restart Just a web server.

This article will introduce to you how to install apache2.4 and how to configure php8.0. The article is accompanied by pictures and detailed steps. Let's take a look at how to install and configure apache2.4+php8.0~

PHP8 can use mysqli and PDO to connect to the database. Detailed introduction: 1. Use mysqli to connect to the database by passing in the database server name, user name, password and database name to connect. Then, use the `connect_error` attribute to check whether the connection is successful and output an error message if the connection fails. Finally, close the connection by calling the `close()` method; 2. Use PDO to connect to the database, and connect by passing in the database server name, password and database name, etc.

The methods of the php8 data type include converting strings to integers, converting integers to strings, converting strings to floating point numbers, converting floating point numbers to strings, converting arrays to strings, converting strings to arrays, and converting Boolean values to integers. Integer conversion to Boolean value and variable type determination and conversion. Detailed introduction: 1. Converting a string to an integer includes the intval() function and (int) forced type conversion; 2. Converting an integer to a string includes the strval() function and (string) forced type conversion; 3. Converting a string to a float Points and so on.

This article will take you through the JIT in PHP 8 and talk about how JIT participates in the interpretation process. I hope it will be helpful to everyone!

The improved performance of php8 includes: 1. Introduction of JIT compiler; 2. Optimization of function calls; 3. Improvement of garbage collection mechanism; 4. Improvement of type system; 5. New language features; 6. Optimized string processing; 7. Improve array processing; 8. Introduce a new memory management mechanism; 9. Optimize code generation. Detailed introduction: 1. The introduction of the JIT compiler. PHP8 introduces the JIT compiler, which is a dynamic compilation technology that can convert PHP code into machine code for more efficient execution; 2. Optimization of function calls, etc.

Features of php8: 1. JIT compiler; 2. Named parameters; 3. Union types; 4. Annotations; 5. Constructor attribute enhancement; 6. Match expression; 7. nullsafe operator; 8. Improved type system; 9 , Error handling improvements; 10. Consistency improvements. Detailed introduction: 1. JIT compiler, PHP8 introduces just-in-time compilation technology, which compiles PHP code into native machine code, thereby improving the execution speed of the program; 2. Named parameters, PHP8 supports named parameters, allowing the use of parameter names when calling functions. etc.
