PHP 文件的 CLI 命令行。
-bash/zsh: php: command not found # Windows (WSL2) sudo apt-get update sudo apt-get install php # Debian apt-get install php # Ubuntu apt-get install php # Alpine apk add php # Arch Linux pacman -S php # Kali Linux apt-get install php # CentOS yum install php-cli # Fedora dnf install php-cli # OS X brew install php # Raspbian apt-get install php # Dockerfile dockerfile.run/php # Docker docker run cmd.cat/php php
php 命令可以以命令行的方式运行，非常灵活：支持交互式 Shell，CLI SAPI 有三种不同的方法执行 PHP 代码：
# 1. 运行指定 php 文件 php my_script.php php -f my_script.php # 2. 在命令行中直接传递 PHP 代码执行 php -r 'print_r(get_defined_constants());' # 3. 通过标准输入（stdin）提供需要运行的 PHP 代码 some_application | some_filter | php | sort -u > final_output.txt
php [options] [-f] <file> [--] [args...] php [options] -r <code> [--] [args...] php [options] [-B <begin_code>] -R <code> [-E <end_code>] [--] [args...] php [options] [-B <begin_code>] -F <file> [-E <end_code>] [--] [args...] php [options] -S <addr>:<port> [-t docroot] [router] php [options] -- [args...] php [options] -a
-a Run as interactive shell
-c <path>|<file> Look for php.ini file in this directory
-n No configuration (ini) files will be used
-d foo[=bar] Define INI entry foo with value 'bar'
-e Generate extended information for debugger/profiler
-f <file> Parse and execute <file>.
-h This help
-i PHP information
-l Syntax check only (lint)
-m Show compiled in modules
-r <code> Run PHP <code> without using script tags <?..?>
-B <begin_code> Run PHP <begin_code> before processing input lines
-R <code> Run PHP <code> for every input line
-F <file> Parse and execute <file> for every input line
-E <end_code> Run PHP <end_code> after processing all input lines
-H Hide any passed arguments from external tools.
-S <addr>:<port> Run with built-in web server.
-t <docroot> Specify document root <docroot> for built-in web server.
-s Output HTML syntax highlighted source.
-v Version number
-w Output source with stripped comments and whitespace.
-z <file> Load Zend extension <file>.
args... Arguments passed to script. Use -- args when first argument
starts with - or script is read from stdin
--ini Show configuration file names
--rf <name> Show information about function <name>.
--rc <name> Show information about class <name>.
--re <name> Show information about extension <name>.
--rz <name> Show information about Zend extension <name>.
--ri <name> Show configuration for extension <name>.
php 命令解析并执行 PHP 脚本：
php path/to/*.php
php 命令检查 PHP 脚本的语法（即 Lint）：
php -l path/to/file
交互式运行 PHP：
php -a ========================================== Interactive shell php > echo 2+3; 5 php > echo 9-6; 3 php > echo 5*4; 20 php > echo 12/3; 4 php > echo 12/5; 2.4 php > echo 2+3-1; 4 php > echo 2+3-1*3; 2 php > exit
运行 PHP 代码 - 无需使用 <? ?> 标签；用反斜杠转义双引号：
php -r "code"
php -r 'phpinfo();'
