Chroot with All Linux Commands

I'm trying to limit a website developer to one directory using chroot. I want to give the developer access to all Linux commands, primarily PHP. I tried to give access to PHP but a bunch of lib files are required and it's a very slow process adding one at a time after errors of missing lib files when run. Is there an easy way to give the user access to all Linux commands? I'm using Centos 7. Thanks
