Select value from listbox

[shaoen01]

In my form i have a listbox which indicates the extract size of my zip file that is to be created. The option values in the listbox is hard-coded and not taken from the database. However, one of the option values are stored in the database, as a default extract size, which is one of the values of the hard-coded listbox.

And i would retrieve the default extract size from the database and make the option value selected, to show it is the default value. My question is how do i select a value in the listbox using php? Thank you

 <select name="extractSize">
    <option value="52428800">50MB</option>
    <option value="41943040">40MB</option>
    <option value="31457280">30MB</option>
    <option value="20971520">20MB</option>
    <option value="15728640">15MB</option>
    <option value="10485760">10MB</option>
    <option value="5242880">5MB</option>
    </select>

let's say for example the default size is 20971520

<?php
$default_size = 20971520;

$sizes = array(
52428800 => 50,
41943040 => 40,
31457280 => 30,
20971520 => 20,
15728640 => 15,
10485760 => 10,
5242880 => 5
);

echo '<select name="extractSize">';
foreach ($sizes as $key => $value)
{
	echo '<option value="' . $key . '"';
	if ($key == $default_size) {echo ' selected';}
	echo '>' . $value . 'MB</option>';
}
echo '</select>';
?>
