<?
require_once('../connect.inc.php');
include('CheckAdmin.php');
if($HTTP_X_FORWARDED_FOR!="")
$REMOTE_ADDR=$HTTP_X_FORWARDED_FOR;
$tmp_ip=explode(",",$REMOTE_ADDR);
$REMOTE_ADDR=$tmp_ip[0];
$ip=$REMOTE_ADDR;
$text=$boardmaster."\t".$ip."\t".$time."\n";
$fp=fopen("log/masterlog.txt","a+");
fwrite($fp,$text);
fclose($fp);
?>
是不是加$符号的全是变量呀.请详细解释一下.

PHP 中一个美元符号后面跟上一个变量名称，即表示一个变量。变量的名称是对大小写敏感的。
<?php
$var = 'Bob';
$Var = 'Joe';
echo "$var, $Var"; // outputs "Bob, Joe"
$4site = 'not yet'; // invalid; starts with a number
$_4site = 'not yet'; // valid; starts with an underscore
$t?yte = 'mansikka'; // valid; '洄 is (Extended) ASCII 228.
?>
