指定命令(cmd)的绝对路径.

Specify the absolute path to the command (cmd).

假设 $ file 是/path/to/file ，则命令 ['php'，"$ file"] 展开到 php/path/to/file .就像在命令行上运行以下命令一样:

Let's say $file is /path/to/file, then the command ['php', "$file"] expands to php /path/to/file. This is like running the following on the command line:

$ php /path/to/file

因为命令( php )是相对的，所以搜索系统路径(在Linux上，系统路径在环境变量 PATH 中)以找到 php.

Because the command (php ) is relative, the system path (on linux the system path is in the environment variable PATH) is searched to find php.

您可以为命令指定绝对路径.假设您安装了以下版本:

You can specify an absolute path for the command. Let's say you have the following versions installed:

• /path/to/php/versions/7.0.0/bin/php
• /path/to/php/versions/5.5.0/bin/php

然后，您可以配置命令以使用v7.0.0:

Then you can configure a command to use v7.0.0:

{
    "cmd" : ["/path/to/php/versions/7.0.0/bin/php", "$file"],
    "file_regex": "php$",
    "selector"  : "source.php"
}

和v5.5.0:

{
    "cmd" : ["/path/to/php/versions/5.5.0/bin/php", "$file"],
    "file_regex": "php$",
    "selector"  : "source.php"
}

依此类推...
