function.php代码：
<?php function counter(){ $file = 'counter.txt'; if(!file_exists($file)){ $num = 0; $cf = fopen($file,"w"); fwrite($cf,$num); fclose($cf); }else{ $cf =fopen($file,"rw"); $num = fgetc($cf); fclose($cf); } $num++; $cf = fopen($file,"w"); fwrite($cf,$num); fclose($cf); return $num; } ?>
counter.php代码：
<?php require("function.php"); ?> <html> <head> <title>访客计数器</title> </head> <body> <h1>欢迎访问</h1> <br> <font size=7 color=red><?php echo counter();?></font> </body> </html>
计数器只能计数到2~10区间？？？？
