Description:
------------
Hello,

First of all I'd like to thank all of you PHP community for your commitment to PHP. This is what makes PHP the best web scripting language on earth. If I could code this function in C, I would, however at this moment I am only a begginner in C/C++ thats why I am posting here :)

Some applications (in my case, a socket server) wich have to be run from the command line and will run forever, need to have some administration functions from the CLI so that you can create basic functions (like shutdown, etc.)

I think that an unbuffered fgetc or fegts function would be very nice so that we can read from php://stdin only if there is something to read, and so that it doesnt hang there waiting for input.

I'd like to give a few urls of other people in need of this, as I might not have explained properly :

Thanks,

Louis

Reproduce code:
---------------
	function getStdI() {
	
	    static $pStdn;
	    
	    if(!$pStdn)
	    {
	        $pStdn = fopen("php://stdin", "r");
	    }

	    	return trim(fgets($pStdn, 1024));
	}

while(1) {
 getStdI(); // will hang there until enter is pressed
 // socket server code
}
