Run php code in command line
提问by kaiseroskilo
I just began learning php. I've installed php5on linux and wrote very simple code just to get going.
我刚开始学习php。我已经php5在 linux上安装并编写了非常简单的代码来开始工作。
How can I run scripts? I tried using the -foption but it works as a catcommand and just spits out the code to STDOUT.
如何运行脚本？我尝试使用该-f选项，但它作为cat命令工作，只是将代码吐出到STDOUT.
The interactive interpreter option works fine. Is a web browser the only way to execute a PHP script?
交互式解释器选项工作正常。Web 浏览器是执行 PHP 脚本的唯一方法吗？

A simple:
一个简单的：
php myScript.php
… should do the job.
......应该做这项工作。
If it is acting like cat, then you probably forgot to switch out of template mode and into script mode with <?php
如果它表现得像 cat，那么您可能忘记使用以下命令从模板模式切换到脚本模式 <?php

Actually, PHP's main purpose is to generate web pages, but there are at least two other options:
实际上，PHP 的主要目的是生成网页，但至少还有两个其他选择：
- command line (CLI) script execution,
- interactive shell- which is actually the variant of the previous option,
- 命令行 (CLI) 脚本执行，
- 交互式 shell- 这实际上是前一个选项的变体，
The first one can be achieved in many ways (eg. by giving proper permissions to the file and calling script by providing its URI, eg. ./index.php), the second one can be invoked by php -acommand (as stated in the documentation mentioned above).
第一个可以通过多种方式实现（例如，通过为文件提供适当的权限并通过提供其 URI 调用脚本，例如./index.php），第二个可以通过php -a命令调用（如上述文档中所述）。

As already mentioned, you can execute your PHP with the following.
如前所述，您可以使用以下命令执行 PHP。
$ php myScript.php
If you wish to pass an argument(s), you can simply do so like this:
如果你想传递一个参数，你可以简单地这样做：
$ php myScript.php Apples
In your PHP file you can use this argument by accessing the $argv array like this:
在您的 PHP 文件中，您可以通过访问 $argv 数组来使用此参数，如下所示：
<?php
echo 'I like ' . $argv[1];
?>
The above would print our "I like Apples". Note the array index is 1 and not 0. 0 is used for script name. In this case $argv would be "myScript.php"
以上将打印我们的“我喜欢苹果”。请注意，数组索引是 1 而不是 0。0 用于脚本名称。在这种情况下 $argv 将是“myScript.php”

Shorter way for command line:
命令行的更短方法：
php -r 'echo "Hello "; echo "Jay";'
ORphp -r 'echo dirname("parent/child/reply") . "\n";'
php -r 'echo "Hello "; echo "Jay";'
或者php -r 'echo dirname("parent/child/reply") . "\n";'
