How to print a number with commas as thousands separators in JavaScript

I am trying to get the value in this format, $1,000,000. Right now I am getting the value in this format, 1000000, and it’s working fine, but I don’t want this. I want it to get the value as $1,000,000 and change it in my PHP code and accept it.

My HTML:

<form action="index.php" method="Get">
    Enter the present value of pet: <input type="text" name="v" value="1000000"/><br>
    Enter the value of the pet you want: <input type="text" name="sv" value="1951153458"/><br>

    <input type="submit" />
</form>

And here is my PHP:

<?php
    $i           = 0;
    $v           = isset($_GET['v']) ? (float) $_GET['v'] : 1000000;
    $sv          = isset($_GET['sv']) ? (float) $_GET['sv'] : 1951153458;
    $petearn     = 0;
    $firstowner  = 0;
    $secondowner = 0;

    And so on..............

My calculator is working fine in this way:

http://ffsng.deewayz.in/index.php?v=1000000&sv=1951153458

But I want it to be:

http://ffsng.deewayz.in/index.php?v=$1,000,000&sv=$1,951,153,458

I’m confused anout how to change this format $1,000,000 to 1000000 this
or if there is other way. Do I need to use any JavaScript code? Before the form is submitted?

Someone tried to help me the following way, but I have no clue on how to use it.

function reverse_number_format($num)
{
    $num = (float)str_replace(array(',', '$'), '', $num);
}

Just replace any non-numerical characters from the string:

$filteredValue = preg_replace('/[^0-9]/', '', $value);

UPD:

$value = '$1,951,1fd53,4.43.34'; // User submitted value

// Replace any non-numerical characters but leave dots
$filteredValue = preg_replace('/[^0-9.]+/', '', $value);

// Retrieve "dollars" and "cents" (if exists) parts
preg_match('/^(?<dollars>.*?)(\.(?<cents>[0-9]+))?$/', $filteredValue, $matches);

// Combine dollars and cents
$resultValue = 0;
if (isset($matches['dollars'])) {
    $resultValue = str_replace('.', '', $matches['dollars']);
    if (isset($matches['cents'])) {
        $resultValue .= '.' . $matches['cents'];
    }
}

echo $resultValue; // Result: 1951153443.34
