Little help using exec

[anler]

Hi there, I'm writing a class and I need to know where is the php binary, but when I use this:

exec('which php')

from inside of my php file, it give me a different output(wrong) that when I use the same command in the shell
I'm using MAMP and the path I want (that used by the shell) is:

/Applications/MAMP/bin/php5/bin

but my class is trying to use /usr/bin instead

thanks to all

Remember that if run from a web app, it's probably being executed by the web server user, not your personal login account. Therefore it may be using a different PATH setting. If you want your script to use a different path, you may need to modify the PATH setting for the Apache user account.
