js变量在php里面循环[重复]
问题描述：
This question already has an answer here:
I am familiar with php but still learning Js. Some people helped me on completing a ajax form to send data to mysql. But now I am stuck on below:
I used while loop as I want to print every thing which matches query
while($row = mysqli_fetch_assoc($result))
{
comment_id = $row['comment_id'];
echo "<script>";
echo "var count = ".json_encode($comment_id);
echo "</script>";
}
But what I get a last value on while loop is assigned to js variable count as php is server sided and js is client sided. Then I tried adding array (as it can hold many values)
while($row = mysqli_fetch_assoc($result))
{
$comment_id = $row['comment_id'];
echo "<script>";
echo "var count = [];";
echo. "count.push($com);";
echo "</script>";
}
But again i am getting last value in while loop. Is there any way I can assign whole data inside a php while loop to js variable.
Thanks :)

I just got an idea and I think it is now resolved. I did is taken a php array inside while loop and assigned it to js array.
$count = [];
while($row = mysqli_fetch_assoc)
$comment_id = $row['comment_id'];
array_push($count,$comment_id);
echo "<script>";
echo "var count =".json_encode($count);
echo "</script>";
}
