PHP echo() Function Usage and Example

PHP String String Functions Manual

　 　 The echo() function is used to output one or more strings

Syntax

void echo ( string $arg1　[, string $... ] )

Definition and Usage

It gives output in the form of one or more strings, output all parameters. It does not wrap.
Echo is not a function (it is a language structure), so you do not necessarily have to use parentheses to indicate parameters, single quotes and double quotes can be used. Echo (unlike 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 multiple parameters to echo, you cannot use parentheses.
Note: The main difference between echo and print is that echo accepts a parameter list and does not return a value.

Return Value

It does not return any value

Parameter

Online Example

Try the following example to output a text string:

<?php
　　　//echo Example Usage
　　　echo 'w'3codebox";
?>

Output Result

w3codebox

More Examples

<?php
//echo Output characters containing HTML tags;
$string = "www.w"3codebox.com!";
echo $string;
echo '<br>Basic Tutorial!';
?>

Difference between single quotes and double quotes. Single quotes will output the variable name, not the value:

<?php
//echo Output strings using single and double quotes separately;
$color = "red";
echo "Pink are $color";
echo '<br>';
echo 'Pink are $color';
?>
