就我现在的知识,用flash做一个网页计数器,可以有3种方法

1.使用数据库,我就会PHP+MySQL
2.不使用数据库,那么就是PHP+TXT
3.后台都不用,直接使用ActionScript的SharedObject;但是这么做,并不能做到真正意义上的网页计数,只能保存当前用户浏览该flash的计数

方法一:

/* MySQL Code */
CREATE TABLE `counter` (
	`count` INT( 20 ) DEFAULT '0' NOT NULL 
);

/* PHP Code */
<?php
$db=mysql_connect("localhost","root");
mysql_select_db("hbbspace");
// 取数
$result=mysql_query("SELECT * FROM counter WHERE 1",$db);
$myrow=mysql_fetch_row($result);
$count = $myrow[0];
// 加 1
$count++;
echo "count=$count"; // 列印
// 更新
$sql="UPDATE counter SET count='$count' WHERE 1";
$result=mysql_query($sql);
?>

/* Flash Code */
loadDate = function (success) {
	if (success) {
		var counters = counter_vars.count;
		count_txt.htmlText = "你是第<font color='#FF0000'>"+counters+"</font>个访问该swf的人";
	}
};
var counter_vars:LoadVars = new LoadVars();
counter_vars.onLoad = loadDate;
counter_vars.load("http://localhost/counter2.php");
this.createTextField("count_txt", 1, 150, 100, 200, 100);
count_txt.html = true;

方法二:

/* PHP Code */
<?php
/* 将计数器归零
这样如果计数器还未被使用，初始值将是1
你当然也可以把初始值设成20000来骗人咯
*/
$count=0;
// 如果存放计数器文件已经存在，读取其中的内容
if ( file_exists($counter_file) )
{
$fp=fopen($counter_file,"r");
// 我们只取了前20位，希望你的站点不要太受欢迎啊
$count=0+fgets($fp,20);
// 由于函数fgets()返回字符串，我们可以通过加0的方法将其自动转换为整数
fclose($fp);
// 对文件操作完毕
}
// 增加一次计数值
$count++;
// 将新的计数值写入文件
$fp=fopen($counter_file,"w");
fputs($fp,$count);
fclose($fp);
# 返回计数值
echo "count=$count<br>";
?>

/* Flash Code */
loadDate = function (success) {
	if (success) {
		var counters = counter_vars.count;
		trace(counters);
		count_txt.htmlText = "你是第<font color='#FF0000'>"+counters+"</font>个访问该swf的人";
	}
};
var counter_vars:LoadVars = new LoadVars();
counter_vars.onLoad = loadDate;
counter_vars.sendAndLoad("http://localhost/counter.php?counter_file=counter.txt",counter_vars,"post");
this.createTextField("count_txt", 1, 150, 100, 200, 100);
count_txt.html = true;

方法三:

var myLSO = SharedObject.getLocal("foo");
if (myLSO.data.counter == undefined) {
	var myCounter = {};
	myCounter.count = 1;
	myLSO.data.counter = myCounter;
	counters = myLSO.data.counter.count;
} else {
	myLSO.data.counter.count++;
	counters = myLSO.data.counter.count;
}
this.createTextField("count_txt", 1, 150, 100, 200, 100);
count_txt.html = true;
count_txt.htmlText = "你是第<font color='#FF0000'>"+counters+"</font>个访问该swf的人";
