php命令行用法简介Php是一个非常流行的web服务端脚本语言。其实，php不仅仅可以在web服务器中充当重要角色。在命令行一样可以执行。
本文中，笔者为各位介绍下php在命令行中的使用方法。
1、 查看php的版本、配置在命令行中输入php –v 即可查看当前php的版本。
java代码PHP5.2.17(cli)(built:Feb2201111:19:21)Copyright(c)1997-2010ThePHPGroupZendEnginev2.2.0,Copyright(c)1998-2010ZendTechnologieswithZendOptimizerv3.3.9,Copyright(c)1998-2009,byZendTechnologieswitheAcceleratorv0.9.6.1,Copyright(c)2004-2010eAccelerator,byeAccelerator其他的选项有： –m、-i。笔者在这里就不给出列子了。
-m 会显示当前php加载的有效模块。
-i 则输出无html格式的phpinfo。
使用 –ini 选项可以输出当前php加载ini配置文件的数量、路径信息。
2、 在命令行中运行php程序从命令行运行php非常简单。但有些注意事项需要各位了解下。诸如$_session之类的服务器变量是无法在命令行中使用的，其他代码的运行则和web服务器中完全一样^_^。
Php代码<?phpecho“运行php命令行echo”;?>
把上面的代码另存为hello.php 。在命令行中敲入 php –f hello.php。显示结果如下：
在命令行中执行php文件的好处之一就是可以通过脚本实现一些计划任务的执行。而毋须通过web服务器^_^。
当然，我们也可以直接在php中调试代码：输入php –r 指令，会出现一个”>”符号。这表示已经进入到php的shell中，可以直接写代码，并执行。
Java代码-bash-3.2$php-r'>for($i=0;$i<2;$i++){>echo"Number:{$i}\n";>}>'Number:0Number:1
还可以使用php –a 命令打开交互模式，输入一行代码，php会实时输出结果。
3、 检测php语法、高亮输出不用执行代码，我们可以在命令行下检测php文件的语法错误。
Java代码-bash-3.2$php-lhello.phpNosyntaxerrorsdetectedinhello.php
程序员经常会需要将php代码高亮原样输出，使用php –s 即可
Java代码-bash-3.2$php-shello.php<code><spanstyle="color:#000000"><spanstyle="color:#0000BB"><?php<br/></span><spanstyle="color:#007700">echo </span><spanstyle="color:#DD0000">'ddd'</span><spanstyle="color:#007700">;<br/></span><spanstyle="color:#0000BB">?><br/></span></span>
在浏览器中的显示效果
4、查看php手册从php5.1.2开始，程序员们可以在php命令行下查看手册了，输入php –rf function。会打印出该函数的语法简介
Java代码-bash-3.2$php--rfstrip_tagsFunction[<internal:standard>functionstrip_tags]{-Parameters[2]{Parameter#0[<required>$str]Parameter#1[<optional>$allowable_tags]}}
如果要查看类使用 –rc；查看扩展使用 –re。
Php命令行的使用方法介绍到这里就结束了。Enjoy It！

php - Unix, linux Command
NAMEphp - PHP Command Line Interface ’CLI’
SYNOPSISphp[options] [-f]file[[--]args...]
php[options]-rcode[[--]args...]
php[options] [-Bcode]-Rcode[-Ecode] [[--]args...]
php[options] [-Bcode]-Ffile[-Ecode] [[--]args...]
php[options] -- [args...]
php[options]-a
DESCRIPTIONPHPis a widely-used general-purpose scripting language that is especially suited for Web development and can be embedded into HTML. This is the command line interface that enables you to do the following:
You can parse and execute files by using parameter -f followed by the name of thefileto be executed.
Using parameter -r you can directly execute PHPcodesimply as you would do inside a.phpfile when using theeval()function.
It is also possible to PRocess the standard input line by line using either the parameter -R or -F. In this mode each separate input line causes thecodespecified by -R or thefilespecified by -F to be executed. You can access the input line by$argn. While processing the input lines$argicontains the number of the actual line being processed. Further more the parameters -B and -E can be used to executecode(see -r) before and after all input lines have been processed respectively. Notice that the input is read fromSTDINand therefore reading fromSTDINexplicitly changes the next input line or skips input lines.
If none of -r -f -B -R -F or -E is present but a single parameter is given then this parameter is taken as the filename to parse and execute (same as with -f). If no parameter is present then the standard input is read and executed.
OPTIONSTag Description
--interactive-a
Run PHP interactively. This lets you enter snippets of PHP code that directly get executed. When readline support is enabled you can edit the lines and also have history support.
--bindpathaddress:port|port-baddress:port|port
Bind Path for external FASTCGI Server mode (CGI only).
--no-chdir-C
Do not chdir to the script’s directory (CGI only).
--no-header-q
Quiet-mode. Suppress HTTP header output (CGI only).
--timingcount-Tcount
Measure execution time of script repeated count times (CGI only).
--php-inipath|file-cpath|file
Look forphp.inifile in the directorypathor use the specifiedfile
--no-php-ini-n
Nophp.inifile will be used
--definefoo[=bar]-dfoo[=bar]
Define INI entryfoowith valuebar
-e
Generate extended information for debugger/profiler
--filefile-ffile
Parse and executefile
--globalname-gname
Make variablenameglobal in script.
--help-h
This help
--hide-args-H
Hide script name (file) and parameters (args...) from external tools. For example you may want to use this when a php script is started as a daemon and
