PHP MySQL submitting dynamic fields, arrays in $_REQUEST - php

Question

I've got a form that has users fill out information for request. In a section of the form, I have an "Add More Phone" button that dynamically adds more text field and drowdown selections so users can add multiple types of phone numbers. Since the number of telephones that will be submitted is unknown, I am trying to figure out how to send all the data into the server so it can be inserted into the database.
Here's my html:
<div class="form-group">
<label class="col-md-4">Tel:</label>
<div class="col-md-8">
<input class="form-control required" name="phones[]" maxlength="14" type="text" placeholder="[phone]">
</div>
</div>
<div class="form-group">
<label class="col-md-4">Phone Type:</label>
<div class="col-md-8">
<select class="form-control" name="phonetypes[]">
<option value="0"><b>Choose a phone type</option>
<option value="1">Main</option>
<option value="2">Fax</option>
<option value="3">Mobile/Direct</option>
</select>
</div>
</div>
<div class="form-group">
<label class="col-md-4"></label>
<div class="col-md-8">
<input onclick="addRow(this.form);" type="button" value="Add Another Phone" name="addphone" class="btn btn-info"></input>
</div>
</div>
The addRow(this.form) appends a new set of fields where you can enter more phone number and the phone types. This is where I'm not sure how the request is going to take the field values since we don't know how many phones will be added.
I have the request as:
if(isset($_REQUEST['action'])) {
$phones[] = $_REQUEST['phone'];
foreach($_REQUEST['phone'] as $phone) {
$phone['phone'];
}
$phonetypes[] = $_REQUEST['phonetype'];
foreach($_REQUEST['phonetype'] as $phonetype) {
$phone['phonetype'];
}
I definitely have no clue on where to go about this from here. Any help appreciated!

Every request parameter can only be sent once with a given name, if it is not an array. So you need to adapt your code to
either use a different name for each phonetype and phone
or use a name as phonetype[] to mark is as an array
