设计一个计数器，测试通过，马上给分

Question

最简单的，一看就懂的那种;
count.php文件;
<?php 
$fp=fopen('count.txt',"w");
$tmpcount=fread($fp,filesize('count.txt'));
$tmpcount++;
$fput=fput($fp,$tmpcount);echo '你是第 '.$tmpcount.'位';
?>

Answer 1

<? 
$memo_file="data.txt"; 
if ($phpxcount<>$REMOTE_ADDR){ 
$visits = file($memo_file); 
$number_of_last_visit = $visits[0]; 
$number_of_new_visit = ++$number_of_last_visit; 
$fp = fopen($memo_file, "w"); 
$fw = fwrite($fp, $number_of_new_visit); 
fclose($fp); $len_str = strlen($number_of_new_visit); 
for($i=(0);$i<$len_str;$i++){ 
$numbers_exploded = substr($number_of_new_visit,$i,1); 
$output_str = $output_str . "<img src=\"$numbers_exploded.gif\">"; 
} 
}else{ 
$visits = file($memo_file); 
$number_of_last_visit = $visits[0]; 
$number_of_new_visit = $number_of_last_visit; 
$fp = fopen($memo_file, "w"); 
$fw = fwrite($fp, $number_of_new_visit); 
fclose($fp); $len_str = strlen($number_of_new_visit); 
for($i=(0);$i<$len_str;$i++){ 
$numbers_exploded = substr($number_of_new_visit,$i,1); 
$output_str = $output_str . "<img src=\"$numbers_exploded.gif\">"; 
} 
} 
echo $output_str; 
?>

<?
$memo_file="counter.txt";    /*save counternum in the boot/counter/counter.txt*/
$visits=file($memo_file);    //get arry from the file
$num =$visits[0];            //get the content of the first line in the file
$num += 1;
exec("rm -rf $memo_file");   //rm old
exec("echo $num > $memo_file"); //create new
?>
document.write("<form name=counter><input type=text name=countshow size=16 style='font-size:9pt; color:#FFFF00; background-color:#000000; text-align:center; line-height:130%; border:3 ridge #00FF00' value=''></form>");
s=new Array(2);
s[0]="第  <?print($num)?>  次"
s[1]="中国计数器"
var id,p=0;
function show(){
    document.counter.countshow.value=s[p];
    p=p+1;
    if(p>1){
          p=0
    }
    id=setTimeout('show()',2000);
}
show();

使用
<script language="javascript" src="count.php3"></script>
