It is quite probable that your command line environment is different from PHP’s.

In order to do what you asked for, you need to specify ec2start with an absolute filename.

First run the following from your command prompt to find the path:

whereis ec2start

It should return a list of paths, just find the one containing ec2start.

Next, simply use that path you found inside your PHP script, like so:

shell_exec('/path/to/ec2start');
