Which correct way to add two fields

Question

Good evening friends, what is the correct way to add up these two fields valuated and adherence and display the total value in the input.

Membership = 3,500.33;
Dependants = 90.33;
Total Correct: 3,590.66

Code

<?php
                     $numerocontrato = trim($_GET["numerocontrato"]);
                     $sql =" SELECT sum(cast(replace(valordependente,',','.') as decimal(18,2))) as dep, replace(adesao,',','.') as ades";
                     $sql .= " FROM cadastro_clientes where numerocontrato = $numerocontrato ";
                     $consulta = $DB->query($sql);
                     while ($linha = $consulta->fetch(PDO::FETCH_ASSOC)) {
                          
                          $soma1 = $linha['ades'];
                          $soma2 = $linha['dep'];
                       
                          $resultadoSoma = $soma1 + $soma2;
                        
           echo "<input type='text' readonly value=" . number_format($resultadoSoma, 2, ',', ' ') . " placeholder='Total' id='total' class='form-control' name='total'><span class='error'></span>";            
                          
                     }
            ?>

This is happening because you’re trying to add up different scores. Use this form, to leave them with the same formatting and then add them up:

$num1="3.500.33";
$num2 = "90.33";
//Remove qualquer pontuação existente
$num1 = str_replace(',','',str_replace('.', '', $num1));
$num2 = str_replace(',','',str_replace('.', '', $num2));

// Adiciona a pontuação correta
$num1 = substr_replace($num1, '.', strlen($num1) - 2, 0);
$num2=substr_replace($num2, '.', strlen($num2) - 2, 0);
echo $num1+$num2;

Edit:

$num1="3.500.33";
$num2 = "90.33";
//Remove qualquer pontuação existente
$num1 = str_replace(',','',str_replace('.', '', $num1));
$num2 = str_replace(',','',str_replace('.', '', $num2));
$soma=$num1+$num2;
$soma=substr_replace($soma, ',', strlen($soma) - 2, 0);
// Adiciona a pontuação correta
echo $soma = substr_replace($soma,'.', strlen($soma)-6,0);

I hope I’ve helped
