In PHP, **`echo()`** is used to output one or more strings in a web browser. However, `echo` is not a function, rather, a language construct and can, therefore, be used with _or_ without the parenthesis. 

However, if multiple parameters are to be passed, they must *not* be enclosed in parenthesis as that will generate an error.

# Syntax

# Examples
Let's take a look at some examples to see how `echo` works.

## 1. Printing a string
The following code prints a string on the browser:

## 2. Printing an integer variable

>**Note:** In order to separate two or more parameters, a comma `,` or a full stop `.` may be used.


<?php 
$x = 5;
echo 'Value of the variable is: ' , $x;
echo ("\n");
echo 'Value of the variable is: ' . $x;?>

## 3. Printing value from an array
The following code will demonstrate how we can print an element from an array:

<?php
$day = array("Monday", "Tuesday", "Wednesday");
echo $day[0] ; ?>
