How to pull out the values of ticked checkboxes using PHP?

while ($row= mysql_fetch_array($result, MYSQL_ASSOC))
{ $id=$row[id];
  $html=<<<html
<tr><td> 
<input style="float:left" type="checkbox" name="mycheckbox"  value="$id">   
<span style="float:left">$row[content]</span>
<span style="color:black;float:right">$row[submitter]</span></td></tr>  
html;
echo $html; 
}

Since the HTML code is generated dynamically, I don't know how long the array "mycheckbox" is and I don't know what checkboxes are ticked or unticked(This is determined by users). How to retrieve the values of ticked checkboxes using PHP?

The way you have it now, mycheckbox will get overwritten and act more like a radio button.

You probably want:

<input style="float:left" type="checkbox" name="mycheckbox[]"  value="$id">

PHP will push the checked values into an array: $_GET['mycheckbox']

<?php 

$values = $_GET['mycheckbox'];
$count = count($values);

echo 'Selected values are: <br/>';

foreach($values as $val) {
    echo $val . '<br/>';
}

echo 'Total Length is: ' . $count . '<br/>';
