am working on an exercise with one compiler

Scan the user's name and say Hello Write a program to scan the user's name and say hello to them.

Example input:

Peter 

Example output:

Hello Peter 

I have written this

<?php $name = 'Peter'; echo("Hello". "$name"); ?>

and I have as an outputHelloPeter

while I need Hello Peter

Hi,

Because a space is missing between .... By exemple add a space after hello.

<?php $name = 'Peter'; echo("Hello ". "$name"); ?>

Bye
