jquery php count loop on name to email - php

Question

In form, I will be adding product info in. looping name eg. pname1, pname2 when add.
I realise now that when i wanna send to email we need the 'name'. what code should i put on php file to loop the pname?
noted: my form and php code is not in the same file.
or i should put them together and click to loop?
Php file put this?
<?php
$x=1;
while($x<=10)
{
echo "The number is: $x <br>";
echo ;
$x++;
}
?>
form in html
<div class="" id="" name="productlist"> <!-- Add Product Here -->
<ol><input class="fpname" type="text" id="addpname"placeholder="Product Name"/><input class="fpqty" type="number" id="addpqty" placeholder="Quantity"/><input class="fpprice" type="text" id="addpprice" placeholder="Price per Item"/><input type="button" id="padd" value="add"/>
</br><font color="red" size="1.5"><i>*Becareful when adding the Product, once added you are unable to edit the information except changing the quantity.</i></font>
</ol>
<ol id="addhereform"><input type="text" class="fpname" value="Product Name" readonly/><input class="fpqty" type="text" id="pqty" value="Quantity" readonly/><input type="text" class="fpprice" value="Total Price" readonly/>
</ol>
<ol><input class="fpname" id="fpships" type="text" Value="" readonly/><input class="fpqty" id="overallqty" type="text" value="" readonly/><input class="fpprice" type="text" id="overallprice" value="" readonly/>
</ol> <!-- Result -->
</div> <!-- Add Product End Here -->
jquery add button
var count = 1;
$('#padd').click(function(){
var pname = $('#addpname').val();
var pqty = $('#addpqty').val();
var pprice = $('#addpprice').val();
var totalpprice = (pqty * pprice).toFixed(2);
$('#addhereform').append('<li><input class="fpname" type="text" id="pname" name="pname' + count + '" value="' + pname + '" readonly/><input class="fpqty" type="number" id="pqty" name="pqty' + count + '" value="' + pqty + '"/><input type="text" id="pprice" name="pprice' + count + '" value="' + pprice + '" readonly hidden/><input class="fpprice" type="text" id="totalpprice" name="totalpprice' + count + '" value="' + totalpprice + '" readonly/><input type="button" id="premove" value="X"/></li>').before('</li>');
count++;
});
Ans:
$name1 = $_POST["name1"];
$name2 = $_POST["name2"];
$name3 = $_POST["name3"];
# and so on...
for($i = 1; $i <=5; $i++){
$productlist = ${'name' . $i};
echo $productlist;}

Thanks for everyones help,
Here's another method(better) I just found. no need to type all the super long loop way.
Stristr is find name keyword.
if($_POST){
foreach($_POST as $key => $value){
if(stristr($k, 'pname')){
echo "$v";
}
if(stristr($k, 'pqty')){
echo "$v";
}
if(stristr($k, 'pprice')){
echo "$v";
}
if(stristr($k, 'ptotalprice')){
echo "$v</br>";
}
}
}
