Enviar email com PHP e javascript

Bom dia! tenho o seguinte código javascript:

function sendEmail() {


document.getElementById("sendFormFran").disabled = true;
    let nome = document.getElementById("nome").value.trim();
    let endereco = document.getElementById("endereco").value.trim();
    let cidade = document.getElementById("cidade").value.trim();
    let estado = document.getElementById("estado").value.trim();
    let cnpj = document.getElementById("cnpj").value.trim();
    let phone1 = document.getElementById("phone1").value.trim();
    let phone2 = document.getElementById("phone2").value.trim();
    let work = document.getElementById("work").value.trim();
    let email = document.getElementById("email").value.trim();


    let interessado = {
      'nome': nome,
      'endereco': endereco,
      'cidade': cidade,
      'estado': estado,
      'cnpj': cnpj,
      'phone1': phone1,
      'phone2': phone2,
      'work': work,
      'email': email
    }

Gostaria de saber como envio para o php essas informações para poder enviar meu e-mail.

<?php
require "phpmailer/class.phpmailer.php";

function send_email_client($email){
    $body = "<table border='0' cellpadding='10' cellspacing='0' style=
