The echo Function
The echo function outputs the passed strings. Unlike the print function, echo can take multiple parameters and does not return a value. It is one of the most frequently used constructs in PHP for outputting data.
Syntax
echo string1, string2, ..., stringN;
Example
Simple string output:
<?php
echo 'Hello World';
?>
Code execution result:
Hello World
Example
Outputting multiple strings:
<?php
echo 'Hello', ' ', 'World';
?>
Code execution result:
Hello World
Example
Outputting variables:
<?php
$name = 'John';
$age = 25;
echo 'Name: ', $name, ', Age: ', $age;
?>
Code execution result:
Name: John, Age: 25
Example
Usage with HTML tags:
<?php
echo '<b>text</b>';
?>
