I have a bunch of checkboxes each with a unique name and value using $_POST method. How can I put the selected values into an array? I started using a for loop, but I don't know how to call only one value at a time or determine whether it has been selected.

You want to do something like this:
<input type="checkbox" name="mycheckarray[]" value="1" />
<input type="checkbox" name="mycheckarray[]" value="2" />
<input type="checkbox" name="mycheckarray[]" value="3" />
<input type="checkbox" name="mycheckarray[]" value="4" />
Check boxes 2 and 4, then at the server side, if you print_r($_POST['mycheckarray']);, you will get something like this:
Array (
[0] => 2
[1] => 4
)

You can create a group of checkboxes.
<form id="form1" name="form1" method="post" action="">
<label><input type="checkbox" name="CheckboxGroup[]" value="checkbox" id="CheckboxGroup1_0" />Checkbox 1</label>
<label><input type="checkbox" name="CheckboxGroup[]" value="checkbox" id="CheckboxGroup1_1" />Checkbox 2</label>
</form>
And after that u can use it as you like. print_r($_POST[CheckboxGroup]);
