I'm trying to make a total sum of a "for" but everything is very crazy or "zeroed" ...

<?php
    for ($i=0; $i < count($data); $i++) {

        $total_receitas_recebidas = 0;
        $total_receitas_a_receber = 0;
        $total_despesas_pagas = 0;
        $total_despesas_a_pagar = 0;

        $sinalNegativo = "";

        if(($data[$i]["tipo"]=="receita")&&($data[$i]["situacao"]=="S")){
            $cor=' style="color:green;"'; 
            $situacao="Receita recebida";
            $total_receitas_recebidas = $total_receitas_recebidas + (float) $data[$i]["valor"];
        }

        if(($data[$i]["tipo"]=="receita")&&($data[$i]["situacao"]=="N")){
            $cor=' style="color:blue;"';
            $situacao="Receita à receber";
            $total_receitas_a_receber = $total_receitas_a_receber + (float) $data[$i]["valor"];
        }

        if(($data[$i]["tipo"]=="despesa")&&($data[$i]["situacao"]=="S")){
            $cor=' style="color:orange;"';
            $situacao="Despesa paga";
            $sinalNegativo = "-";
            $total_despesas_pagas = $total_despesas_pagas + (float) $data[$i]["valor"];
        }

        if(($data[$i]["tipo"]=="despesa")&&($data[$i]["situacao"]=="N")){
            $cor=' style="color:red;"';
            $situacao="Despesa à pagar";
            $sinalNegativo = "-";
            $total_despesas_a_pagar = $total_despesas_a_pagar + (float) $data[$i]["valor"];
        }

        echo '<tr>';
        echo '<td>';echo $data[$i]["info_para_cliente"];  echo '</td>';
        echo '<td>';echo converteDataParaMostrar($data[$i]['data_vencimento']);  
        echo '</td>';
        echo '<td><p'.$cor.'><b>';echo 'R$ '.$sinalNegativo.number_format($data[$i]["valor"], 2, ',', '.'); echo '</b></p></td>';
        echo '</tr>';
    }


echo '<input type="hidden" id="total_receitas_recebidas" value="'.number_format($total_receitas_recebidas, 2, ',', '.').'">';
echo '<input type="hidden" id="total_receitas_a_receber" value="'.number_format($total_receitas_a_receber, 2, ',', '.').'">';
echo '<input type="hidden" id="total_despesas_pagas" value="'.number_format($total_despesas_pagas, 2, ',', '.').'">';
echo '<input type="hidden" id="total_despesas_a_pagar" value="'.number_format($total_despesas_a_pagar, 2, ',', '.').'">';

I made tests with a value of "150.00" x4 records but it returns "300.00" ????

obs: this is a simple cash flow, the query seeks revenue and expenses and crosses everything.

I have an equal template in another project and it works perfect ...

You are zeroing the totalizers at each step of the loop, in addition to the totalizers being cumulative, I suggest that your code looks like this:

$total_receitas_recebidas = 0;
$total_receitas_a_receber = 0;
$total_despesas_pagas = 0;
$total_despesas_a_pagar = 0;


for ($i=0; $i < count($data); $i++) {

    if(($data[$i]["tipo"]=="receita")&&($data[$i]["situacao"]=="S")){
        [...]
        $total_receitas_recebidas += $total_receitas_recebidas + (float) $data[$i]["valor"];
    }

    if(($data[$i]["tipo"]=="receita")&&($data[$i]["situacao"]=="N")){
       [...]
        $total_receitas_a_receber += $total_receitas_a_receber + (float) $data[$i]["valor"];
    }

    if(($data[$i]["tipo"]=="despesa")&&($data[$i]["situacao"]=="S")){
        [...]
        $total_despesas_pagas += $total_despesas_pagas + (float) $data[$i]["valor"];
    }

    if(($data[$i]["tipo"]=="despesa")&&($data[$i]["situacao"]=="N")){
        [...]
        $total_despesas_a_pagar += $total_despesas_a_pagar + (float) $data[$i]["valor"];
    }

    echo [...]
}

In addition, it seems to me that your $ negative variable is not required, since the number_format function preserves the original numeral signal.

Doubt about attributes and methods POO in PHP Which event should I associate with select?

First you are instantiating the calculation variables within the for each loop ie it zeros the calculation, put the following variables out of the loop and test again:

$total_receitas_recebidas = 0;
$total_receitas_a_receber = 0;
$total_despesas_pagas = 0;
$total_despesas_a_pagar = 0;
