Well, I tried something simple...
$ php -r 'echo "hello world\n";'
Error in argument 1, char 2: option not found r
Error in argument 1, char 2: option not found r
Usage: php [-q] [-h] [-s] [-v] [-i] [-f <file>]
php <file> [args...]
-a Run interactively
-C Do not chdir to the script's directory
-c <path>|<file> Look for php.ini file in this directory
-n No php.ini file will be used
-d foo[=bar] Define INI entry foo with value 'bar'
-e Generate extended information for debugger/profiler
-f <file> Parse <file>. Implies `-q'
-h This help
-i PHP information
-l Syntax check only (lint)
-m Show compiled in modules
-q Quiet-mode. Suppress HTTP Header output.
-s Display colour syntax highlighted source.
-v Version number
-w Display source with stripped comments and whitespace.
-z <file> Load Zend extension <file>.
This means my install can't run inline stuff like this? Guess it wasn't set
up to do that. So no I won't say that I will use php -r to test anything..
lol :)
Still, thanks for your help, I was playing around with it and wanted to see
what other cool stuff you could do.
