Answer 1

first you should have a POST request;

The $_POST Variable
The $_POST variable is an array of variable names and values sent by the HTTP POST method.

The $_POST variable is used to collect values from a form with method="post". Information sent from a form with the POST method is invisible to others and has no limits on the amount of information to send.

Here is a working example with a test array instead of the $_POST

<?php
$testVar = ['test1', 'test2', 'test3'];
for($index=0;$index<3;$index++)
{

$name=$testVar[$index];
$varvar=$name;
echo $name.'<br/>';
}
?>
