What is PHP in echo?

In PHP, echo is a statement that can be used to output anything on the browser, such as numbers, array, strings, characters, variable values and the result of expressions.

Further, in some instances where you want to use multiple parameter it is better to use an echo with a parenthesis echo(). And echo is a language construct and not a function.

The following listed below are the important points that you need to know about echo statements.

  • The echo statement is much faster than the print statement.
  • The echo statement which mainly used for displaying the output on the browser.
  • With the use of echo statement we can pass multiple display strings which have been separated by a comma (,) in an echo.
  • The echo statement can both used with or without a parenthesis echo() or echo.
  • The echo statement doesn’t return any kind of value.

Syntax

echo(string ...$expressions): void

    echo "PHP is powerful programming language!"."\n";
    echo "Welcome to the world of PHP development!"."\n";
    echo "You will be learning PHP into a easiest!"."\n";

What is PHP echo and print?

The echo and print statement is more likely the same in terms of their functionalities for output data into a terminal or in the browser. But there are still small differences. As I mentioned above the PHP echo is not a function and has no return value, while the print statement has a return value of 1. So it means that it can be used in expressions for data output.

Further, the echo statement can take one or more parameters (even though the usage is so rare) while the PHP print statement can take only one argument.

Example

<?php
    echo "PHP is powerful programming language!"."\n";
    echo "Welcome to the world of PHP development!"."\n";
    echo "You will be learning PHP into a easiest!"."\n";
    echo "Here ", "at ", "ITSOURCECODE.COM ", "were ", "tutorial and free source code is the best!."."\n";
    
    print ("PHP is powerful programming language!")."\n";
    print ("Welcome to the world of PHP development!")."\n";
    print ("You will be learning PHP into a easiest!")."\n";
    //line break print ("Here ", "at ", "ITSOURCECODE.COM ", "were ", "tutorial and free source code is the best!.");
?>
