PATH in terminal and in PHP is different

Question

I have next result of command sudo -u www-data echo $PATH in terminal:

/home/denis/node-v0.12.0/bin:/home/denis/node-v0.12.0/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

I have next result in PHP if I run command echo `echo \$PATH`:

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

PATH in terminal and in PHP is different. I don't understand why.

Which user runs what script is irrelevant. Daemons do not start from a login shell. Sudo inherits your current environment unless configured to change it. — symcbean, Apr 04 '15 at 11:13

Running the command literally as given

sudo -u www-data echo $PATH

the $PATH is expanded by your shell before doing a sudo (and show your $PATH). However, if you quoted this properly, it could be deferred into the sudo'd user, and expose a different problem.

Unless you make special provision for this (an option to sudo, which may/may not work), environment variables such as PATH are reset to system defaults when using sudo. For further discussion see
