为什么在终端中运行这个shell脚本时会出错？

Question

I'm trying to get Doctrine 2 working with Codeigniter 2, and have come across a problem while trying to get Doctrine console up and running, which involves executing a shell script which runs a few lines of php.

I'm using this as a reference: Integrating Doctrine 2 with CodeIgniter 2

I'm new to OSX and new to unix commands but I'm confident I have set up the shell script properly as follows:

#!/usr/bin/env php
<?php
chdir(dirname(__FILE__));
include('doctrine.php');

and I have the php file doctrine.php in the same directory.

Whenever I try to run the script with:

bash doctrine

I get this error:

doctrine: line 2: ?php: No such file or directory
doctrine: line 3: syntax error near unexpected token `dirname'
doctrine: line 3: `chdir(dirname(__FILE__));'

It looks to me like php isn't even running at all. I have the feeling I'm doing something fairly basic wrong!

Any help appreciated, Mark.

It's a PHP script, not a bash script.

php doctrine

If you meant for the shebang line to be used then you need to make it executable and run it directly.

chmod +x doctrine
./doctrine
