When i submit a form where is a dot in the name it's changes to "_".
for example:
<form action="<=$PHP_SELF>" method="post" name="aaa">
	<input type="text" size="12" name="127.0.0.1" value="66.55">
	<input type="submit" value="send me">
</form>

when runing in PHP:
foreach ($HTTP_POST_VARS as $key=>$val){
	echo "$key = $val<BR>";
}

the output will be : 127_0_0_1 = 66.55

That's intended behaviour. You can't have dots in variable names, the dot is already used for string concatenation.

Bogus.

even if you use &#046; it's been replaced to "_".
in many other languages this is possible.

<form action="" method="post" name="aaa">
	<input type="text" size="12" name="12.13&#046;14" value="66.66">
	<input type="submit" value="send me">
</form>

Maybe in other languages but not in PHP. As Markus already
said, '.' is reserved character in PHP.

Even if you encode it it will be seen as . in server side.
