the eregi_replace seems to have a problem with replacing backslach.
I made a function that should replace a \ with \\
and I got this error message:
<b>Warning</b>:  eregi_replace(): REG_EESCAPE:Ptrailing backslash (\) in ....

Reproduce code:
function JavascriptEncode($str1)
	$str1 = eregi_replace(chr(92),chr(92).chr(92),$str1);
	return $str1;
this fonction doesn't work.

function JavascriptEncode($str1)
	$str1 = eregi_replace(chr(92).chr(92),chr(92).chr(92),$str1);
	return $str1;
this fonction replace \ by \\ ( it works, but why ???)
