Login system php

Question

Hello,

I am creating a site with login system in php, and I have the following problem,

When I enter Login it does not check in the database if the information exists.

I wish I knew what mistake I’m making.

Follows the Code:

<p>
    <label for="email">E-mail:</label><br>
    <input required type="text" id="email" name="email" size="35">
</p>


<p>
    <label for="senha">Senha:</label><br>
    <input type="password" id="senha" name="senha" required>
</p>

 <input type="submit" value="enviar" name="enviar">

    if( empty($_POST["email"]) || empty($_POST["senha"]) ){
        echo "Digite o Login";
    }else {
        $email = $_POST['email'];
        $senha = $_POST['senha'];

        // Verificando se o usuário/e-mail existe no sistema
        $usuarios = buscaUsuario($conexao, $email);



        // Processo de login
                if( password_verify($senha, $usuarios['senha']) ){
                entrar($usuarios['id'],$usuarios['email'],$usuarios['senha']);
                header("location:posts.php");
            } else {
            echo "Login não encontrado";
            }   
    }       
    }
