This tutorial is all about PHP echo.
The echo command in PHP is used to output the text in the web browser. And echo is not a function, but it is a language construct. Meaning you don’t need to use a parenthesis with it.

How to output a String?
In retrieving a string output in PHP, we use echo. We place a string variable or we can use quotes, like what we are going to do in this example.
The code below we output a “Hello everyone!”. And the text we outputting is being sent to the user in a form of web page and it is very important to use a proper HTML syntax.
In the second echo, we simply put the <h3> tag at the beginning and closed it at the end of the string. Because we are using PHP to make web pages.

PHP CODE

  1. <!--?php &lt;br ?--> $greetings = "Hello everyone!";
  2. echo $greetings;
  3. echo "
  4. <h3>PHP programming is fun!</h3>
  5. ";
  6. ?&gt;

Display:
Hello everyone!
PHP programming is fun!

Echoing Variables

In echoing variables using PHP is very easy because there’s no quotations are required even if the variable does not hold a string.

PHP CODE

  1. <!--?php $myFirstName = "I am Christian "; $myLastName = "Ignacio am "; $age = 21; echo $myFirstName; echo $myLastName; echo $age. " Years old"; ?-->

Display:
I am Christian Ignacio am 21 Years old
