Copy output without output buffering - php

Question

I have a PHP script that write into consol some logs,erros etc.
I want to save all this information into a variable for sending an email at the end of its execution.
I know i can use obstart and co for doing that but I also want that during its execution that the logs appear in real time. So I don't think the output buffering is the solution for my problem but I don't see another solution.
Is there a way for doing that please ?
Thanks by advance

You will have to come up with some kind of custom logger that apart from outputing messages to console will also send an email on script shutdown. Something like this:
interface MailerInterface {
function send($recipient, $title, $body);
}
interface LoggerInterface {
function log($message);
}
class ConsoleLoggerWithMailer implements LoggerInterface {
/**
* #var string[]
*/
private $messages = array();
/**
* #var MailerInterface
*/
private $mailer;
/**
* #var string
*/
private $recipient;
public function __construct() {
register_shutdown_function(array($this, 'sendMessages'));
}
/**
* #param MailerInterface $mailer
* #param string $recipient
*/
public function setMailer(MailerInterface $mailer, $recipient) {
$this->mailer = $mailer;
$this->recipient = $recipient;
}
/**
* #return string[]
*/
public function getMessages() {
return $this->messages;
}
public function log($message) {
$this->messages[] = $message;
printf("%s\n", $message);
}
public function sendMessages() {
if ($this->mailer === null || count($this->messages) === 0)
return;
$this->mailer->send($this->recipient, 'log', implode("\n", $this->messages));
}
}
Usage example assuming you also created some Mailer class implementing MailerInterface:
$mailer = new Mailer();
$logger = new ConsoleLoggerWithMailer();
$logger->setMailer($mailer, "webmaster#example.com");
$logger->log("Starting...");
$logger->log("Doing...");
$logger->log("End");
