echo response PHP vs println Scala

Question

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.

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.
