PHP动态取得的数组值如何传入javascript??

[javy101]

我从数据库中取得了以下PHP数组值
<?php 这里连数据库是成功的,略去!
$sql = "SELECT id,title,img,content FROM main WHERE fid=0 AND sid=1 AND img<>'' ORDER BY time DESC limit 0,5";
$result=mysql_query($sql);
$i=0;
while($a=mysql_fetch_array($result))
{ //echo $a[0];
$news_img_a=explode(":",$a['img']);
$pic[$i]="/safety/main/".$news_img_a[0];
$url[$i]="/safety/view.php?id=".$a['id'];
$alt[$i]=getTitle($a['title']);
$i++;
}
echo $pic[0]."<br>"; / 取得的值 /safety/main/20051127173015.gif
echo $pic[1]."<br>"; // 取得的值 /safety/main/20051126150605.jpg
echo $pic[2]."<br>"; // 取得的值 /safety/main/20051019165714.jpg
echo $pic[3]."<br>"; // 取得的值 /safety/main/20050922095458.jpg

?>
现想把这个$ pic[]这个数组的值,放入 javascript ,在javascript里如何实现啊?这个数组里的值主要是作为图片新闻在首页的动态显示的.可以做成动态的链接的,图片一张一张显示是通过javascript实现的.现请高手指点,谢谢!下面附上javascript程序:

你的JS有点长啊。
如果PHP在前，JS代码在后，只要直接在JS中这样写
a = '<?php echo $pic[0];?>'
如果PHP在后，JS在前，就得不到值了，除非你通过某种方式刷新该页面，通过.php?参数=参数值这样传递。当然数组是不能直接传递的，要通过转换。查一下手册的implode和explode函数就知道要怎么处理了。

就是用php把javascript代码打出来就可以了啊，比如说你用php从数据库里得到一个字符串'123456'放在$b里面，然后你想用javascript把$b打印出来，那就这样写就可以了：
print <<<END
<script type = "text/javascript">
alert({$b}
</script>
END;
这样就把变量传过去了，基本上php到javascript传递变量就是这样了

对于zalvsa的指导 问题就是,在 <script></script>中放入<? ?>在javascript里是不能识别的啊,认为是不合法的代码吧
对于 assassin 的指导.我在试一下,以前没有用过,先谢谢两位了.

[zalvsa]

识别啊，LZ自己去试一下就知道了。

直接输出就好!
