如何在数组中存储值php

Question

这是我的代码，用于显示问题列表和4个选项（使用选项框）。用户必须选择正确的选项。是否可以将用户选择的选项存储在数组变量中。可能有10到20个问题数组变量应该只包含选项值。

<?php 
require('connect.php'); 
$display=mysql_query("SELECT * FROM Java_Test_1 ORDER BY id ASC"); 
echo "<form method=post action=$PHP_SELF>"; 
echo "<table border=0>"; 
while ($row = mysql_fetch_array($display)) 
{ 
$id=$row['0']; 
$question=$row['1']; 
$opta=$row['2']; 
$optb=$row['3']; 
$optc=$row['4']; 
$optd=$row['5']; 
$answer = $row["woptcode"]; 
echo "<tr><td colspan=3><br><b>$question</b></td></tr>"; 
echo "<tr><td>$opta<input type=radio name=$id value='a'></input></td><td>$optb <input  type=radio name=$id value='b'></input></td><td>$optc <input type=radio name=$id value='c'> </input></td><td>$optd <input type=radio name=$id value='d'></input></td></tr>"; 
} 
echo "</table>"; 
echo "<input type='submit' value='start' name='doo'>"; 
echo "</form>"; 
} 

Answer 1

$name = 'opt'; 
$counter = 0; 
while ($row = mysql_fetch_array($display)) 
{ 


$name = 'opt'.$counter; 
$counter++; 

$id=$row['0']; 

$question=$row['1']; 
$opta=$row['2']; 
$optb=$row['3']; 
$optc=$row['4']; 
$optd=$row['5']; 
$answer = $row["woptcode"]; 
echo "<tr><td colspan=3><br><b>$question</b></td></tr>"; 
echo "<tr><td>$opta<input type=radio name=$name value='a'></td> 
<td>$optb <input type=radio name=$name value='b'></td> 
<td>$optc <input type=radio name=$name value='c'></td> 
<td>$optd <input type=radio name=$name value='d'></td> 
</tr>"; 
}
