[PHP] location of the PHP executable
Hi, I have looked in the documentation but can't find it: My PHP script (which is run from the command prompt - CLI) needs to know the file system location of the PHP executable. This is because it needs to run a second PHP script. I know about the which command but it's not available in all OSes, and that might not be the currently running executable anyway. I could prompt the user for this, but that seems kind of silly. Surely, there must be some way of looking it up automatically?

I think they will be helpful if there isn't a way to do what I'm looking for: Ideally, I would like to get the location of the PHP executable that is actually executing the script. I'm thinking there would be some way to find out while the script is executing. Something like: ?php $executable_location = get_location_of_current_executable(); //fictitious function echo $executable_location .\n; ? Running it from the command line (again fiction): $ /my-location-of/php myscript.php /my-location-of/php $ I was hoping there's a function or $_SERVER property that would contain this?

have you tried looking for this info you want?
I can't say for sure if it always exists but on the few boxes
I tried I found and entry in both $_SERVER and $_ENV:

on windows (where my php cli install is a bit borked),
I didn't find it but I did find PHPRC which points to
the directory that the php executable lives in.
these maybe of some use.
then again what ever it is your trying to do with the php script
you seem to need to run inside another instance of php could probably
be run within the context of the calling script - if you run it inside
a function you can stop any kind of variable scope clashes (assuming there are
no symbol name clashes [e.g. duplicate functions/classes]):
function runit()

it's just a thought.

Yup, but the manual seems kind of light on the subject.

I found these in $_ENV and $_SERVER, on Linux. I don't have handy access

That's at least something. If someone could confirm, that would be great.
I used the following command (at the command-line) to check the contents
of $_SERVER:
php -r 'print_r($_SERVER);'
Obviously, $_ENV can be checked similarly.
these maybe of some use.

Re: [PHP] location of the PHP executable
your script should try it's best to find the executable, on failure
you might consider having it mail an error to you so at least you
can pre-empt the client with regard to getting things working.
most windows machines will probably have there php binary at:
$_ENV['PHPRC'].'php.exe'
variations on the exe name can be (IIRC):
'php-win.exe'
'php-cli.exe'
I think you can be pretty sure about $_ENV['_'] on *nix
systems.
another to consider is a simple installer which tries to
find the exe and on failure offers the user a prompt to say where it
is .. that info can then be stored for use at a later date.
