PHP在while循环中添加+1

Question

我有while循环,并且有论坛帖子.我想显示帖子数量(1,2 ..).

让我告诉你我的想法

while($some = mysql_fetch_array($forum_posts)){
echo 'Number of post is $num++';
}

并表现出来

------线程-------

------帖子-------

Text of post            1.
Text of post            2.
Text of post            3.

谢谢.抱歉英语不好

$ num必须初始化!

$num = 1;
while($some = mysql_fetch_array($forum_posts)){
echo 'Number of post is '.($num++);
}
