Command line instruction parsing

I've been all over google and haven't been able to find a regex that would parse (correctly) CLI arguments.

Does anyone have in their code library such a thing?

Ideally it would parse all styles of arguments (i.e.: -v -abc --arg=val --arg="val1 val2" --arg "val")

Thanks!

P.S.: This would be used in PHP context (preg)

From stackoverflow

• Have a look at PEAR's Console_Getopt or the Zend Framework Zend_Console_Getopt

  Your PHP version may have support for getopt as a built-in also.

  vartec : actually it's not in PEAR anymore, it's a standard function

  Paul Dixon : it is in PEAR, Seems SO does odd things with URLs containing underscores, have changed the link...

• Not sure if this would help with this question, but try RegexLib. It's an inmense Regex library :)

• Thanks for the fast replies, I did have a look into those 2, the only problem is that they don't allow anonymous options, every option has to be defined in the first place to be matched

• The global $argv already parses the command line arguments automatically if you're running CLI. Also see: Using PHP from the command line

• getopt()

• @acrosman: $argv parses the arguments just partially, i.e.: it extracts them individually but you still have to build the logic that extracts the arguments into property -> value

  vartec : "comment", nor "answer" for comments

• Just thought I'd let you know I found a solution.
