How to print in php: echo and print in php

Today we are going to learn how to print in PHP.

echo in PHP:
The echo() function outputs one or more strings. Return Value: No value is returned.

example:

<?php
echo "Hello world!";
?>

Output:
Hello world!

other example:
<?php
$foo = "foobar";
$bar = "barbaz";
echo "foo is $foo"; // foo is foobar
?>

other example: Join two string variables together
<?php
$str1="Hello world!";
$str2="What a nice day!";
echo $str1 . " " . $str2;
?>

output:
Hello world! What a nice day!
