php
$count_num=0;
if(file_exists("counter.txt"))
{
$fp=fopen("counter.txt","r");
$counter_num=fgets($fp,9);//读取前八位数字
$count_num++;
fclose($fp);
}
$fp=fopen("counter.txt","w");
fputs($fp,$count_num);
fclose($fp);
echo" hahaha $count_num hahah";
?>
$count_num=0;
if(file_exists("counter.txt"))
{
$fp=fopen("counter.txt","r");
$counter_num=fgets($fp,9);//读取前八位数字
$count_num++;
fclose($fp);
}
$fp=fopen("counter.txt","w");
fputs($fp,$count_num);
fclose($fp);
echo" hahaha $count_num hahah";
?>
