[求助]自己写的计数器出的问题？？

<?php function counter() { $max_len = 8; $counterfile = "../zzx.txt"; if(!file_exists($counterfile)) { $counter = 0; $cf = fopen($counterfile,"w"); flock($cf,3); fputs($cf,"0"); fclose($cf); } else { $cf = fopen($counterfile,"r"); flock($cf,3); $counter = trim(fgets($cf,$max_len))+0; fclose($cf); } } if(session_is_registered("in")==false) { $counter=$counter+1; //这里是24行； $cf = fopen($counterfile,"w"); flock($cf,3); fputs($cf,$counter); fclose($cf); } $counter_len = strlen($counter); for($i=1;$i<=($max_len-$counter_len);$i++) { echo "<img src='image/0.GIF'>"; } for($i=1;$i<=$counter_len;$i++) { echo "<img src='image/".substr($counter,$i-1,1).".GIF>'"; }
 ?> 错误：==== Notice: Undefined variable: counter in d:\usr\www\html\phpexe\jishuqi\counter\tqjsq_do.php on line 24
