php教程写的网页计数器代码

$countfile = "counter.txt";
//定义计数器写入的文件是当前目录下的counter.txt文件中,然后我们应当测试该文件能否打开
if (($fp = fopen($countfile, "r+")) == false) {
 //用读写模式打开文件,若不能打开就退出
 printf ("open file %s failed!",$countfile);
 exit;
}
else
{
//如果文件能够正常打开,就读入文件中的数据,假设是1
$count = fread ($fp,10);
//读取10位数据
$count = $count + 1;
//count ++
fclose ($fp);
//关闭当前文件
$fp = fopen($countfile, "w+");
//以覆盖模式打开文件
fwrite ($fp,$count);
//写入加1后的新数据
fputs($fp,$fg);
//显示计数结果
// 数字显示
echo "

计数次数:$count
";

// 图形模式计数
$fp = fopen ($countfile, "r"); //以只读模式打开文件
$array_count = 1; //定义一个表示数组元素位置的变量,下面要用
while (! feof($fp)) {
$current_number = fgetc($fp);
$counter_array[$array_count] = $current_number;
$array_elements = count ($counter_array);
$array_count = $array_count + 1;
}
echo "

计数次数:";
for ($array_id = 1;$array_id echo "php写的网页计数器代码";
}
echo "
";

fclose ($fp);
//并关闭文件
}

?>
