推荐答案
PHP 命令行脚本仍然必须在其中包含
PHP command line script still have to have the <? opener in them.
#!/usr/bin/php
echo "hi mom!\n";
不行，必须要
#!/usr/bin/php
<?php
echo "hi mom!\n";
这是因为没有php脚本"这样的东西.只有各种文本文件嵌入了 PHP 代码块.即使在 CLI 模式下，PHP 也期望/要求至少看到一个 <? 块.否则解释器不会启动，也不会看到任何代码，即使您已经声明它是带有 shebang 的 PHP 脚本.
This is because there's no such thing as a "php script". There are only various text files that have PHP code blocks embedded within them. Even in CLI mode, PHP expects/requires to see at least one <? block. Otherwise the interpreter won't kick in and won't see any of the code, even though you've stated it's a PHP script with the shebang.
PHP cli 模式基本上是事后的想法.PHP 最初是作为一个服务器端 CGI 脚本解析器，并没有从根本上改变这种模式.
PHP cli mode is basically a hacked-in afterthought. PHP started out as a server-side CGI script parser and has not fundamentally changed from that mode.
