How to check the return of a function

Question

Galera set up a function that executes the class phpmailer and send an email. However I do not know how to check her return and know if the email was sent. Good follows the function:

    function envia_email($destinatario) {

        // Aqui fica todos os dados da função


        // Envia o e-mail
        $email->Send();
    }

What sends the email and this command $email->Send();.

And I call it that:

envia_email($destinatario);

Well, how do I know if it’s true or false?

Answer 1

You need to review the library you are using, take a look at its documentation and see the return of send().

However, if you are using PHPMailer which it is customary to use you can observe here:

Creates message and assigns Mailer. If the message is not sent successfully then it Returns false. Use the Errorinfo variable to view Description of the error. Returns true on Success, false on Failure.

This method it returns true or false for sending. Therefore, you can use this return.

function envia_email($destinatario) {

    // Aqui fica todos os dados da função


    // Envia o e-mail
    return $email->Send(); // true or false
}

$retorno = envia_email($destinatario);

if($retorno === false){
   throw new Exception('Email não foi enviado.');
}

Simple.

Answer 2

It returns True or False:

if(!$Email->Send()) {
   echo A mensagem não foi enviada.";
   echo Mensagem de erro: " . $Email->ErrorInfo;
} else {
    echo "Mensagem enviada!";
}

Answer 3

I use this code, works well and reports errors.

if(!$email->Send()) :
$mensagemRetorno = 'Erro ao enviar formulário: '. print($email->ErrorInfo);
else : 
echo"<script>alert ('Email enviado!')</script>";
endif;
