PHP制作图形计数器的例子
请看如下例子实现图形计数器,在网页中使用请用 <script src="http://文件地址"></script>
- <?
- //存放计数的文本文件
- $count="count.txt";
- //计数器的位数，如果不填则默认为6位
- $wei="";
- //图像的URL路径
- $tu="http://127.0.0.1/tcount/images";
- ?>
- <?
- if ($wei=="") { $wei=6; }
- if (!file_exists($count)) { $fp=fopen($count,"w+"); fputs($fp,0,100); fclose($fp); }
- if ($REMOTE_ADDR!=$ip) {
- $fp=fopen($count,"r+");
- $cc=fgets($fp,100);
- $cc=trim($cc);
- if ($cc=="") { $cou=1; }
- else { $cou=$cc+1; }
- rewind($fp);
- fputs($fp,$cou,100);
- fclose($fp);
- }
- setcookie("ip",$REMOTE_ADDR,time()+86400);
- $fp=fopen($count,"r+");
- $cou=fgets($fp,100);
- $cou=trim($cou);
- fclose($fp);
- $w=strlen($cou);
- while($w<$wei) {
- $cou="0".$cou;
- $w++;
- }
- $www=strlen($cou);
- $i=0;
- echo "document.write("<p align=center>"); ";
- while($i<$www) {
- $ym=substr($cou,$i,1);
- echo "document.write("<img src=$tu/$ym.gif>"); ";
- $i++;
- }
- ?>
