Using Echo

 

As per http://php.net echo — Output one or more strings.

A string is a type of data. A string can contain letters, numbers or characters. Although a string can contain numbers, it is not a numeric value. A string can be short or long.

To display anything on web server, we need to echo. There are some other options available to display content on server, but most of the time echo is used to display content on web browser.

php.net states, echo is not actually a function (it is a language construct), so you are not required to use parentheses with it. echo (unlike some other language constructs) does not behave like a function, so it cannot always be used in the context of a function. Additionally, if you want to pass more than one parameter to echo, the parameters must not be enclosed within parentheses.

// Lets try some examples
<?php echo "My first test with echo and php!"; 

// The semicolon at the end of the statement is important!

<?php 
// print also works like echo, we will differentiate more
print "Hello World, php sounds easy to me!";
?>

<?php

/* Difference Between print and echo

echo - can output one or more strings
print - can only output one string, and returns always 1

*/

?>

I think that’s enough for a novice for first class. This was just an overview of what php is. We will be learning lot of things ahead.

Next Chapter would cover Variables.

Next Chapter would cover concatenation. We will learn how to do concatenation for two or more strings. I hope you remember what is a string, if not, go through above chapter again.

So today we learned, syntax of php, how to add single line and multi line comments, What is a String, What is echo, what is print, and what is difference between echo and print. I hope you liked this tutorial on getting started guide with PHP.
