I have several checkbox (I don't know number of them) that create from a loop in a form.

```
<form>
<input type="checkbox" name="id" value="id">
<input type="checkbox" name="id" value="id">
...//create in a loop
<input type="checkbox" name="id" value="id">
</form>

```

My question is that How can I read them, If I use `<?php $_REQUEST['id']; ?>`, it only reads the last checkbox.
