为什么老是显不出来0以后数据，代码如下，
<?
function counter()
{
$max_len=8;
$counterfile="coun.dat";
if (!file_exists($counterfile))
{
$counter=0;
$cf=fopen($counterfile,"w");
flock($cf,3);
fputs($cf,"0");
}
else
{
$cf=fopen($counterfile,"r");
flock($cf,3);
$counter=trim(fgets($cf,$max_len));
fclose($cf);
}
if (session_is_registered("in")==flase)
{
$counter++ ;
$cf=fopen($counterfile,"w");
flock($cf,3);
fputs($cf,$counter);
fclose($cf);
}
$counter_len=strlen($counter);
for($i=1;$i<=($max_len-$counter_len);$i++)
{
echo "<img src='img/0.gif'>";
}
//下面这句总是用图片显不出来，请帮我看一下！
for ($i=1;$i<=$counter_len;$i++)
{
echo "<img src='img/" .substr($counter,$i-1,1) . "gif'>";
}
}
?>

for ($i=1;$i<=$counter_len;$i++)
{
echo "<img src='img/" .substr($counter,$i-1,1) . ".gif'>";//这里少了个"."

ok,谢谢，刷新后数字为什么不+1，我已将:
if (session_is_registered("in")==flase)
{
$counter++ ;
$cf=fopen($counterfile,"w");
flock($cf,3);
fputs($cf,$counter);
fclose($cf);
}
取了！这又是为什么？Top
