I have a questionnaire form with 5 questions, each having 5 radio button options. Now, I want to capture this form data upon pressing of a Submit button. I am getting stuck at populating an array with values of these radio buttons sent through a POST method.
The code that I have written is throwing the error: "Notice: Undefined index: 'radio11' in E:\xampp\htdocs\dataCollect\form1.php on line 11"
The code is enclosed below:
<?php
if (isset($_POST['btnForm1'])){
for($count = 1; $count < 6; $count++){
$radioName = "radio1".$count;
$arrForm1 = array($_POST["'".$radioName."'"]);
}}
<?>

This is incorrect:
$arrForm1 = array($_POST["'".$radioName."'"]);
^^^^----------^^^^----useless
The "'" quotes are absolutely unecessary. This is all that you should have:
$arrForm1 = array($_POST[$radioName]);
And why wrap the radio button's value in an array. You'll only ever get back one value from each radio button set anyways.
