ERROR Parse error: syntax error, Unexpected '<'

Question

this error appears in my code: Parse error: syntax error, Unexpected '<' in /home/Storage/3/da/ca/public_html/Viewrevisao.php on line 110

What would be the solution in this case

<?php
            include_once("conexao.php");
            $result_cursos = "SELECT DISTINCT b.prefixo as idVeiculo, max(datatroca) as datatroca, max(kmtroca) as kmtroca, max(horimetroca) as horimetroca, max(proximatroca) as proximatroca, max(c.horimetro) as horimetroatual, (a.proximatroca - max(c.horimetro)) as horasrestantes, idMecanico FROM revisao a

You’re putting PHP inside PHP. This is wrong $query = ("UPDATE revisao SET status = '$status1' WHERE idVeiculo = '".<?php echo $row_usuario['idVeiculo']; ?>."'") or die (mysql_error()); That’s right $query = ("UPDATE revisao SET status = '$status1' WHERE idVeiculo = '".$row_usuario['idVeiculo']."'") or die (mysql_error());

I improved the identation and put only PHP.

<?php

include_once("conexao.php");

$result_cursos = "SELECT DISTINCT b.prefixo as idVeiculo, max(datatroca) as datatroca, max(kmtroca) as kmtroca, max(horimetroca) as horimetroca, max(proximatroca) as proximatroca, max(c.horimetro) as horimetroatual, (a.proximatroca - max(c.horimetro)) as horasrestantes, idMecanico FROM revisao a
              JOIN veiculos b on (a.idVeiculo=b.idVeiculo)
              JOIN hodometro c on (a.idVeiculo=c.idVeiculo)
              GROUP BY a.idVeiculo order by datatroca DESC; ";

$resultado_cursos = mysqli_query($conn, $result_cursos);

while ($rows_cursos = mysqli_fetch_assoc($resultado_cursos)) {
            echo "<tr>
            <td>".$rows_cursos['idVeiculo']."</td>
            <td>".date('d/m/Y', strtotime($rows_cursos['datatroca']))."</td>
            <td>".$rows_cursos['kmtroca']."</td>
            <td>".$rows_cursos['horimetroca']."</td>
            <b> <td>".$rows_cursos['proximatroca']."</td><b>
            <td>".$rows_cursos['horimetroatual']."</td>
            <td><b>".$rows_cursos['horasrestantes']."<b></td>
            <td>";            

    if ($rows_cursos['horasrestantes'] >= 150) {

        $status1 = "A VENCER";

        $query  = ("UPDATE revisao SET status = '$status1' WHERE idVeiculo = '".$row_usuario['idVeiculo']."'") or die (mysql_error());
        $result = mysqli_query($conn,$query);

        echo '<button class="btn btn-success btn-sm" type="button">A vencer</button>';

    } elseif ($rows_cursos['horasrestantes'] > 1) {

       $status2 = "VENCEDO";

       $query  = ("UPDATE revisao SET status = '$status2' WHERE idRevisao ='".$rows_cursos['idVeiculo']."'") or die (mysql_error());
       $result = mysqli_query($conn,$query);

       echo '<button class="btn btn-warning btn-sm" type="button">Vencendo</button>';

    } elseif ($rows_cursos['horasrestantes'] <= 0) {

        $status3 = "VENCIDA";

        $query  = ("UPDATE revisao SET status = '$status3' WHERE idRevisao ='".$rows_cursos['idVeiculo']."'") or die (mysql_error());
        $result = mysqli_query($conn,$query);

        echo '<button class="btn btn-danger btn-sm" type="button">Vencida</button>';

     }

      echo '</tr>';
} 

?>
