见了鬼了, $_request的问题.

Question

while(!is_null ($_REQUEST['thisAnswer_id'. ++$counter]));这行后面的";"号去掉....后面还差个 } 号.

Answer 1

另:
你对数组的使用也有问题..
<?php
$counter =0;
$temp = 0;
$thisAnswer_id=array();
while(!is_null ($_REQUEST['thisAnswer_id'. ++$counter]))
{
++$temp;
echo "~~ temp is ".$temp."~~ ";
echo "~~ Counter is " .$counter. "~~ ";
$thisAnswer_id[$counter] = $_REQUEST['thisAnswer_id'.$counter];
}
print_r($thisAnswer_id);
?>
