PHP echo statement

Secondary Nav

Description

In PHP the two basic constructs to get outputs are echo and print. Actually, echo() is not a function, it is a language construct, therefore, you can use it without parentheses.

Display string, variable with echo

Syntax

 echo (arg1, arg2... )

Example : Simple string display

<?php 
echo 'One line simple string.<br />'; 
echo 'Two line simple string example<br />'; 
echo 'Tomorrow I \'ll learn PHP global variables.<br />'; 
echo 'This is a bad command : del c:\\*.* <br />'; 
?>

All the above echo commands simply display the corresponding string, here we have used an additional html command <br /> at the end of each echo statement to generate a line break as \n cannot generate a line break in browser.

Example : Variable inside echo statement

<?php
// Variables inside an echo statement.
$abc='We are learning PHP';
$xyz='w3resource.com';
echo "$abc at $xyz <br />";
// Simple variable display
echo $abc;
echo "<br />"; // creating a new line
echo $xyz;
echo "<br />"; // creating a new line
// Displaying arrays
$fruits=array('fruit1'=>'Apple','fruit2'=>'Banana');
echo "Fruits are : {$fruits['fruit1']} and 
{$fruits['fruit2']}" ;
?>

Output :

We are learning PHP at w3resource.com
We are learning PHP
w3resource.com
Fruits are : Apple and Banana
