How to take a form's checkboxes and turn them into an array to update a mysql database with php

I have a form that has rows in a table that will post to itself.
Each row has a checkbox with an ID to be used to insert or update a mysql table with data from other form parts,
For example: SIDs 38, 39 and 33 are to be updated with status='paid' , forMonth = 'Apr', amount = '8000'.

How do I create an array of the SIDs that I can use in a mysql insert/update statement?
Note that it might be that later, I will have in the table, along with the checkboxs, a dropdown that has typical amounts that are overpaid, which could be different between each SID.
<form name='theTable' METHOD='POST' ACTION='' >
		<SELECT NAME='status'>
			<OPTION value = 'tuition' selected>PAID</option>
			<OPTION value = '10000'>OVERPAID</option>
			<OPTION value = '0'>VACATION</option>

			<input type="radio" name="genre" value="Jan"}	>Jan&nbsp; 
			<input type="radio" name="genre" value="Feb"}	>Feb&nbsp; 
			<input type="radio" name="genre" value="Mar"}	>Mar&nbsp; 
			<input type="radio" name="genre" value="Apr"}	>Apr&nbsp; 
			<input type="radio" name="genre" value="May"}	>May&nbsp; 
			<input type="radio" name="genre" value="Jun"}	>Jun&nbsp; 
			<input type="radio" name="genre" value="Jul"}	>Jul&nbsp; 
			<input type="radio" name="genre" value="Aug"}	>Aug&nbsp; 
			<input type="radio" name="genre" value="Sep"}	>Sep&nbsp; 
			<input type="radio" name="genre" value="Oct"}	>Oct&nbsp; 
			<input type="radio" name="genre" value="Nov"}	>Nov&nbsp; 
			<input type="radio" name="genre" value="Dec"}	>Dec&nbsp; 

<INPUT TYPE='submit' class='positive' VALUE='Update Selected Items' />

<table id="test2" cellpadding="0" cellspacing="0" border="0" class="rowstyle-alt colstyle-alt no-arrow paginate-40">
<thead>  <tr>
    <th>Modify</th><th class='sortable-text datatype-text'>Name</th><th class='sortable-text datatype-text'>Last Name</th><th>Tuition</th><th>Month</th><th>Edit</th>
    <tr class='alt'>
	 <td><center><input type='checkbox' class='field checkbox' name='29' id='29' value='29'></center></td>
<td>      Mar, </td>  <td><a href='3b1.php?sid=29'>EDIT</a></td>
    </tr>    <tr class='alt'>
	 <td><center><input type='checkbox' class='field checkbox' name='17' id='17' value='17'></center></td>
<td>      Apr, </td>  <td><a href='3b1.php?sid=17'>EDIT</a></td>

Can you please clarify the question?  I'm not sure what you're asking and my answer may be off base, but I'll try.

This statement may not work out well because of the curly brace:
<input type="radio" name="genre" value="Jan"}      >Jan&nbsp;

To pass an array of elements in an HTML form to a PHP script, you use notation similar to JavaScript array notation.  You can use the square brackets on the end of the request element name.  You can put a string inside the square brackets to give named keys to the array, or you can just leave them empty and you'll get a numerically indexed array.

Here is an example:
<?php // demo/form_checkbox_arrays.php
 * Demonstrate how to use an array of checkboxes in a form

if (!empty($_POST))
    echo '<pre>';
    echo '</pre>';

$form = <<<ENDFORM
<form method="post">

These checkboxes have the name "box"
<input name="box[red]" type="checkbox" />Red
<input name="box[grn]" type="checkbox" />Green
<input name="box[blu]" type="checkbox" />Blue

These checkboxes have the name "nbr"
<input name="nbr[]" type="checkbox" />Zero
<input name="nbr[]" type="checkbox" />One
<input name="nbr[]" type="checkbox" />Two

These checkboxes have the name "ray"
<input name="ray[]" type="checkbox" value="sml" />Small
<input name="ray[]" type="checkbox" value="med" />Medium
<input name="ray[]" type="checkbox" value="lge" />Large

<input type="submit" />

echo $form;

yea, I wound up changing the form element's name in order to create an array.  I then looped through it on return to the page to ensure I was capturing the data properly.  I'm now working on poking it into the database.
