Handling HTML Form Array with PHP

Question

I'm having a really hard time trying to figure out how to handle this:
I'm trying to create two arrays, where I enter 4 quizzes for a class, and then loop through them in my PHP code.

<tr>
<td>ENGL110</td>
<td><input type="text" name="EnglArray[]"></td>
<td><input type="text" name="EnglArray[]"></td>
<td><input type="text" name="EnglArray[]"></td>
<td><input type="text" name="EnglArray[]"></td>
</tr>

<tr>
<td>MATH242</td>
<td><input type="text" name="MathArray[]"></td>
<td><input type="text" name="MathArray[]"></td>
<td><input type="text" name="MathArray[]"></td>
<td><input type="text" name="MathArray[]"></td>
</tr>

This is how I'm trying to retrieve it in my PHP code

$EnglArray = $_POST["EnglArray"];

$MathArray = $_POST["MathArray"];

print_r($EnglArray);

I can't figure out what I'm doing wrong, but it seems like my array is always empty, and print_r doesn't output anything.

Answer 1

This should work.

<?php
  foreach ($_POST as $key=>$value){
   if (!is_array($value)){
     echo "$key = $value<br />";
   } else {
     echo "$key is an array:<br />";
     foreach ($value as $valKey=>$valVal){
      echo "$valKey = $valVal<br />";
     }

   }
  }
?>
