Sending multiple flags

I am creating a used car website (written in PHP) and I am late in submitting advanced search options from a form. I have more than 30 of them, and I wonder if it is possible and how to send them to one variable (for example, &options=1,2,3,5,6,10or in some other way ..).

I also heard that this is possible with "bitwise", but I do not know how to do this. Or, if anyone has a better idea, please let me know.

Thank.

You can send them to an array.

<form method="post">
    <input type="checkbox" name="param[]" value="blue" />
    <input type="checkbox" name="param[]" value="red" />
    <input type="checkbox" name="param[]" value="orange" />
    <input type="checkbox" name="param[]" value="green" />
    <input type="checkbox" name="param[]" value="black" />
    <input type="submit" value="Submit" />
</form>

>> $_POST['param']
array('blue', 'orange')

You can even use multidimensional arrays:

<form method="post">
    <input type="checkbox" name="param[color][]" value="blue" />
    <input type="checkbox" name="param[color][]" value="red" />
    <input type="checkbox" name="param[color][]" value="orange" />
    <input type="checkbox" name="param[color][]" value="green" />
    <input type="checkbox" name="param[color][]" value="black" />
    <input type="checkbox" name="param[year][]" value="1999" />
    <input type="checkbox" name="param[year][]" value="2000" />
    <input type="checkbox" name="param[year][]" value="2001" />
    <input type="checkbox" name="param[year][]" value="2002" />
    <input type="checkbox" name="param[year][]" value="2003" />
    <input type="submit" value="Submit" />
</form>

>> $_POST['param']['color']
array('blue', 'green')

>> $_POST['param']['year']
array('2001', '2004')
