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.
- $greetings = "Hello everyone!";
- echo $greetings;
- echo "<h3>PHP programming is fun! </h3>";
PHP programming is fun!
In echoing variables using PHP is very easy because there’s no quotations are required even if the variable does not hold a string.
- $myFirstName = "I am Christian ";
- $myLastName = "Ignacio am ";
- $age = 21;
- echo $myFirstName;
- echo $myLastName;
- echo $age. " Years old";
I am Christian Ignacio am 21 Years old
