Upload data from MYSQL to PHP Form

Hello, I am preparing a form to load data from a MYSQl database, it is the same data that I enter, I just want that in this form they can be edited, the code I have is:

 <?php
// 1) Conexión

if ($conexión = mysql_connect("localhost", "root", "clave")){
echo "<p>MySQL le ha dado permiso a PHP para ejecutar consultas con ese usuario</p>";

// 2) Preparar la orden SQL

$consulta= "SELECT*FROM mensajes";

// 3) Ejecutar la orden y obtener datos

mysql_select_db("cursos");
$datos= mysql_query ($consulta);

// 4) Ir Imprimiendo las filas resultantes

while ($fila =mysql_fetch_array($datos)){
echo "<p">;
echo $fila ["id"];
echo "-"; // un separador
echo $fila["nombre"];
echo "-"; // un separador
echo $fila ["email"];
echo "-"; // un separador
echo $fila["mensaje"];
echo "</p>";
}

}else{
echo "MySQL no conoce ese usuario y password";
}
?> 

this works but not only I want to show them (echo), what I want is to inject the data to the HTML form (name, email, etc), with the purpose of editing the information previously entered, (without using javascript)

<!-- formulario de contacto para el ingreso de datos -->



<form action="envia.php" method="post" class="form-consulta"> 
        <label>Nombre y apellido: <span>*</span>
            <input type="text" name="nombre" placeholder="Nombre y apellido" class="campo-form" required>
        </label>

        <label>Email: <span>*</span>
            <input type="email" name="email" placeholder="Email" class="campo-form" required>
        </label>

        <label>Consulta:
            <textarea name="consulta" class="campo-form"></textarea>
        </label>

        <input type="submit" value="Enviar" class="btn-form">
    </form>

<!-- formulario -->

I found an unconventional way with javascript and it works for me but I want to do it, more suitable, to avoid that the script blockers cancel the function,: D I accept your comments, help and suggestions, greetings to all
