Saving Radio Button Inputs into Array - php

Question

I am working on a custom survey that is dynamically populated with database information and needs to be saved as an array. I can make everything work as it should except I would like to use a star rating system for many of the answers and it seems radio buttons won't work like this:
<input type="radio" name="surveyRating[]" value="1" />
<input type="radio" name="surveyRating[]" value="2" />
<input type="radio" name="surveyRating[]" value="3" />
<input type="radio" name="surveyRating[]" value="4" />
<input type="radio" name="surveyRating[]" value="5" />
Because there are multiple instances of this same code. This will be saved into an array so surveyRating will be used over and over again. If I click a radio button in one group, it changes to a radio in another group.
I have read I can possibly do this with checkboxes instead. Is that the best alternative? Or is there another option I should be looking at? I want the final product to be star ratings 1-5. Not sure if I can do that with checkboxes.
EDIT
Ok so using name="surveyRating[1]" is helping as far as the radio buttons not conflicting on the client side. However, it is not saving correctly the way I have my php set up now. Here is how it is saved currently. What do I need to change to make the [1] work appropriately. Currently it is only saving the last iteration.
$new = array();
$ratings = $_POST['surveyRating'];
$count = count( $ratings );
for ( $i = 0; $i < $count; $i++ ) {
if ( $ratings[$i] != '' ) {
$new[$i]['surveyRating'] = stripslashes( strip_tags( $ratings[$i] ) );
}
}
EDIT 2
So to demonstrate how I accomplished this using the answer below, I had to add [0] as the first iteration in the loop. I was using $items = 0; $items++ to dynamically add a number to each loop.
To make it start at 0, I set $items = -1 that way the first iteration is 0 instead of 1. Hope that makes sense.

Answer 1

Yep, it does because you have the name with []. That's for array. Remove it and you will get it without array:
<input type="radio" name="surveyRating" value="1" />
<input type="radio" name="surveyRating" value="2" />
<input type="radio" name="surveyRating" value="3" />
<input type="radio" name="surveyRating" value="4" />
<input type="radio" name="surveyRating" value="5" />
For radio buttons with several groups, you have to do something like this:
<!-- Group 1 -->
<input type="radio" name="surveyRating[1]" value="1" />
<input type="radio" name="surveyRating[1]" value="2" />
<input type="radio" name="surveyRating[1]" value="3" />
<input type="radio" name="surveyRating[1]" value="4" />
<input type="radio" name="surveyRating[1]" value="5" />
<!-- Group 2 -->
<input type="radio" name="surveyRating[2]" value="1" />
<input type="radio" name="surveyRating[2]" value="2" />
<input type="radio" name="surveyRating[2]" value="3" />
<input type="radio" name="surveyRating[2]" value="4" />
<input type="radio" name="surveyRating[2]" value="5" />
