How to send this XML to webservice via PHP

Question

Good morning, I have the following problem:

I need to remove from the city website which companies issued note this month.

I did the processes of installing the certificate of the city, and I need the answer of this xml:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <BuscarUsuario xmlns="http://www.e-governeapps2.com.br/">
      <imu>string</imu>
      <cnpj>string</cnpj>
    </BuscarUsuario>
  </soap:Body>
</soap:Envelope>

I stopped here, I can’t send, let alone give the certificate, some hint where to search this?

Good morning, a tip is to search the project Nfephp, class "Tools", it makes use of Curl and also digital certificate, see https://github.com/nfephp-org/nfephp/blob/master/libs/NFe/ToolsNFe.php

Already in https://github.com/nfephp-org/nfephp/tree/master/libs/Common/Certificate you find examples of using Digital Certificate. For example, I believe you will need functions like the openssl_pkcs12_read.
