PHP : Display a message using a function without using echo

Here开发者_如何学C's a simple php function.

function hello($name) {
  $message = 'Hello '.$name.' How are you feeling today?';
  return $message;
}

And as you know, when I execute this function it returns a message.

<?php
  echo hello(Stackoverflow);
?>

Output :

Hello Stackoverflow How are you feeling today?

Is there any way to display this message without using the echo (at least not here)

like <?php hello(Stackoverflow); ?> and it should return the message.

If that's the case, your function should have echo.

function hello($name) {
  $message = 'Hello '.$name.' How are you feeling today?';
  echo $message;
}

There are many ways to display something. printf is very useful in this case.

<?php
function hello($name){
   printf('Hello %s How are you feeling today?', $name);
}
?>

If short tags is on <?= hello('Stackoverflow') ?> should work. But it's not recomended to use it.

function hello($name) {
  $message = 'Hello '.$name.' How are you feeling today?';
  echo $message;
}

You can always print it to the PHP error log: http://php.net/manual/en/function.error-log.php

<?= hello('String') ?>
