echo response PHP vs println Scala

I have below PHP function code which echoes the server's response.

PHP Code

function printMessage($errMsg){
    $color='#ffffff';
    echo "<table style=>";
    echo "<tr bgcolor='".$color."'> ".randomFun($errMsg, 0)."</tr>";
    echo "</table>";
}

I have to migrate the same in Scala(new with Scala).

Scala Code

def printMessage(errMsg: String): Unit = {
val color = "#ffffff"
val formattedErrMsg = randomFun(errMsg, 0)

println(
  s"""<table style="">
     |  <tr bgcolor='$color'>
     |    $formattedErrMsg
     |  </tr>
     |</table>
""".stripMargin
)
}

Well, I am unsure if this will behave the same way as the echo in PHP. Looking for a way in Scala to echo the response on server as in PHP.

Solution

  • No, the println function will not work the same way as echo in php. If you want to write a service in Scala, then you need to use the appropriate frameworks.

    For example:

    Play Framework - https://www.playframework.com/

    Akka-http - https://doc.akka.io/docs/akka-http/current/introduction.html

    http4s - https://http4s.org/v0.20/service/

    println() - this is a simple function to output a message to the console.
