Calling PHP function for BAT file

I need to create a BAT file that should be executed every day on 25th. It should run a function named emailAnnountables (), which has been defined for programming a website within two files (controller and model).

Since I took over this website from another developer and it used an application to perform this function every 25th, I would need the BAT file to do the same. I believe that using PHP commands for the Windows prompt might be the solution. But I still have not found the correct commands on the internet to execute this controller function directly.

My role within the Model directory file:

public function emailAniversariantes(){
$data = getdate();
$mes = $data[mon];
$ano = $data[year];
if($mes==12){
    $mes = 1;
    $ano = $ano+1;
}else{
    $mes = $mes+1;
    if($mes<10){
        $mes = '0'.$mes;
    }
}

$sqlUnidades = "select id, nome from unidade where ind_unidade_ativa=1 order by nome";
$resUnidades = System::element('db')->query($sqlUnidades);

$corpo = "";
$corpo .= "<div style='float:left;width:100%; height:3px; background-color:gray; margin-bottom:20px;'></div>";

$corpo .="<div style='font-family:Lucida Sans; font-size:13px;' color='black'>
            <br>Bom dia.<br>Segue abaixo a relação dos aniversariantes do próximo mês.<br>
            Se possível, sugerimos que entrem em contato com eles para desejar feliz aniversário!<br><br><br>
            </div>";

foreach ($resUnidades as $rUnidades){
    $sql = "Select u.id as id_usuario, i.id as id_investidor, uu.id_unidade, un.nome nome_unidade, u.email, 
            DATE_FORMAT(i.data_nasc, '%d/%m/%Y') as data_nasc, i.razao_social as nome, i.telefone, i.nome_responsavel,
            (Select count(*) from usuario u join usuario_unidade uu on (uu.id_usuario = u.id) join investidor i on (i.id_usuario = u.id)

            join unidade un on (un.id = uu.id_unidade)

$arrayEmails = array();
$arrayEmails[0]="[email protected]";
$arrayEmails[1]="[email protected]";
$arrayEmails[2]="[email protected]";
Util::enviaEmail("Remetente", $arrayEmails, "Aniversariantes ".$mes."/".$ano, $corpo,implode(";",$arrayEmails));
return "1";
}

How the function is called by the Controller file:

public function emailAniversariantes() {
$retorno = CadAdmin::emailAniversariantes();
echo $retorno;
}

Thank you for helping me.
