Question

这里的职能简单。

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);
?>

产出:

Hello Stackoverflow How are you feeling today?

如果不使用回馈(至少在这里)来显示这一信息,是否有办法。

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

Answer 1

如果情况如此,您的职能应当有<条码>。

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

Answer 2

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);
}
?>

Answer 3

如果在<代码>和t上贴有短标签;?= hello(Stackoverflow )?>? 但它不赞成使用否决权。

Answer 4

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