以了计数器的漂亮，我们经常会用图片做统计的数字1,2到10我们只要做0，9的图片数字，然后用下面的方法就来做出漂亮的计数器出来哦。

 $fp = fopen ($countfile, "r"); //以只读模式打开文件
 $array_count = 1; //定义一个表示数组元素位置的变量，下面要用
 while (! feof($fp)) {
  $current_number = fgetc($fp);
  $counter_array[$array_count] = $current_number;
  $array_elements = count ($counter_array);
  $array_count = $array_count + 1;
 }
 //显示代码
 echo ("<table border="0" height="5" align="left"><tr><td  align="center">欢迎您，第");

 for ($array_id = 1;$array_id < $array_elements; ++ $array_id) {
  echo ("<img" width=100% src="./img/$counter_array[$array_id].gif" align=absmiddle>");
 }
