在命令行上执行一串PHP代码 [英] execute a string of PHP code on the command line
问题描述
我想在命令行上运行一行PHP代码，类似于以下选项的工作原理：
I'd like to be able to run a line of PHP code on the command line similar to how the following options work:
:~> perl -e "print 'hi';"
:~> python -c "print 'hi'"
:~> ruby -e "puts 'hi'"
我想要能够： p>
I'd like to be able to do:
:~> php "echo 'hi';"
我读过，有一个-r选项可以做我需要的php，但是它似乎不可用，当我尝试使用它。我试过使用PHP 5.2.13和PHP 4.4.9，也没有-r选项。
I've read that there is a -r option that can do what I need for php, however it doesn't appear to be available when I try to use it. I've tried using PHP 5.2.13 and PHP 4.4.9 and neither have an -r option available.
我写了这个脚本（我叫run_php.php） - 工作，但我不是一个巨大的粉丝，只是因为我觉得应该有一个更正确的方式来做。
I wrote this script (that I called run_php.php) - which works, but I'm not a huge fan of it just because I feel like there should be a more "correct" way to do it.
#!/usr/bin/php5 -q
<?php echo eval($argv[1]); ?>
我的问题是：是否有-r选项？如果是这样，为什么当我运行--help它不可用？如果没有-r选项，什么是最好的方法（如果可能，不编写中间脚本）？
My question is: is there a -r option? If so, why is it not available when I run --help? If there is no -r option, what is the best way to do this (without writing an intermediary script if possible)?
谢谢！

因为我不认为上面很清楚，所以-r选项不可用我。这是我运行的两个版本的PHP的php -h输出。
Because I don't think it was very clear above, the -r option is NOT available to me. Here is the php -h output for both versions of PHP that I'm running.
PHP 4.4.9
PHP 4.4.9
Usage: php [-q] [-h] [-s] [-v] [-i] [-f <file>]
php <file> [args...]
-a Run interactively
-C Do not chdir to the script's directory
-c <path>|<file> Look for php.ini file in this directory
-n No php.ini file will be used
-d foo[=bar] Define INI entry foo with value 'bar'
-e Generate extended information for debugger/profiler
-f <file> Parse <file>. Implies `-q'
-h This help
-i PHP information
-l Syntax check only (lint)
-m Show compiled in modules
-q Quiet-mode. Suppress HTTP Header output.
-s Display colour syntax highlighted source.
-v Version number
-w Display source with stripped comments and whitespace.
-z <file> Load Zend extension <file>.
php 5.2.13
php 5.2.13
Usage: php [-q] [-h] [-s] [-v] [-i] [-f <file>]

-c <path>|<file> Look for php.ini file in this directory
-n No php.ini file will be used
-d foo[=bar] Define INI entry foo with value 'bar'

-s Display colour syntax highlighted source.
-v Version number
-w Display source with stripped comments and whitespace.
-z <file> Load Zend extension <file>.
没有-r选项。当我尝试使用-r选项时，我得到：
There is NO -r option. When I try to use the -r option I get:
Error in argument 1, char 2: option not found r
对于混淆而感到抱歉。
推荐答案
EDIT2：是的，它在 PHP 5.2's cli SAPI 。
Yep, it's there in PHP 5.2's cli SAPI.
编辑：如果您无法升级在PHP 5.2中没有这样的选项（我没有手头测试）的情况下，你可以这样做：
If you cannot upgrade and that's the case that there's no such option in PHP 5.2 (I don't have it at hand to test), you can do this:
glopes@nebm:~$ echo "<?php echo \"hi\\n\";" | php
hi
原文：
code> -r 选项（虽然我不确定PHP 5.2）：
There is indeed a -r option (though I'm not sure about PHP 5.2):
D:\>php -r "echo 'hi';";
hi
只需确保您使用的是命令行版本的PHP。 php --version 应该给你这样的东西（注意cli）：
Just make sure you are using the command line version of PHP. php --version should give you something like this (notice "cli"):
D:\>php --version
