Invoking a PHP script

sneakyimp · 05-24-2008, 02:39 PM

I have noticed that sometimes I can invoke a php script like this:

Code:

linux_prompt# php -q my_script.php

but other times I must type in the full path to the php executable like this:

Code:

linux_prompt# /usr/bin/php5 my_script.php

Why is that? I'm guessing there's an alias somewhere. Is it in my bash profile? Is it possible to create one alias that applies to *all* users of a linux box? Also, is it safe to use the path /usr/bin/php every time or will that path vary by linux distribution or php install?

Any help would be very much appreciated.

Are you seeing that different behaviour as the same user,
or are you su'ed to someone else?

Cheers,

I'm not talking about different behavior on a single machine. I'm talking about different behavior from server to server.

For server to server differences, it means its not always being set in the PATH var.
Fundamentally, you've got
/etc/profile
which is applied to all user logins, and
.bash_profile
which is a hidden file in the home dir of each user and can contain different info eg PATH definitions, for each user.

If the location of an application is not in your PATH, then you will have to type the full path name - this is true for every application, not only for PHP.

To run PHP from the command-line it has to have been built with the CLI option. This can be different among different servers.
