解决方案

编辑：当我完成你的测试，这里是最后的网址：

<一个href=\"http://hofstrateach.org/Roberto/process.php?keys=Grade1&keys=Nathan&keys=North%20America&keys=5&keys=3&keys=no&keys=foo&keys=blat&keys=0%3A0%3A24\" rel=\"nofollow\">http://hofstrateach.org/Roberto/process.php?keys=Grade1&keys=Nathan&keys=North%20America&keys=5&keys=3&keys=no&keys=foo&keys=blat&keys=0%3A0%3A24

这可能是一个错误的URL。当您在查询中传递重复键，PHP使他们的数组。上述网址也许应该是这​​样的：

<一个href=\"http://hofstrateach.org/Roberto/process.php?grade=Grade1&schoolname=Nathan&region=North%20America&answer\" rel=\"nofollow\">http://hofstrateach.org/Roberto/process.php?grade=Grade1&schoolname=Nathan&region=North%20America&answer[]=5&answer[]=3&answer[]=no&answer[]=foo&answer[]=blat&time=0%3A0%3A24

这将为大多数领域的各个条目，使$ _GET ['答案']是由用户提供的答案的数组。

底线：解决您的Flash文件

foreach ($_GET as $field => $label)
{
   $datarray[]=$_GET[$field];
   echo "$_GET[$field]";
   echo "<br>";
}
print_r($datarray);

---

This is the output I am getting. I see the data is there in datarray but when I echo $_GET[$field]

I only get "Array"

But print_r($datarray) prints all the data. Any idea how I pull those values?

OUTPUT

Array ( 
        [0] => Array ( 
                 [0] => Grade1 
                 [1] => ln 
                 [2] => North America 
                 [3] => yuiyyu 
                 [4] => iuy 
                 [5] => uiyui 
                 [6] => yui 
                 [7] => uiy 
                 [8] => 0:0:5 
                 ) 
)

解决方案

EDIT: When I completed your test, here was the final URL:

http://hofstrateach.org/Roberto/process.php?keys=Grade1&keys=Nathan&keys=North%20America&keys=5&keys=3&keys=no&keys=foo&keys=blat&keys=0%3A0%3A24

This is probably a malformed URL. When you pass duplicate keys in a query, PHP makes them an array. The above URL should probably be something like:

http://hofstrateach.org/Roberto/process.php?grade=Grade1&schoolname=Nathan&region=North%20America&answer[]=5&answer[]=3&answer[]=no&answer[]=foo&answer[]=blat&time=0%3A0%3A24

This will create individual entries for most of the fields, and make $_GET['answer'] be an array of the answers provided by the user.

Bottom line: fix your Flash file.
