Echo and Print
The echo and print functions provide a way to write out the value of a variable or argument to the screen.
echo
The echo()
function writes out the value of a variable or argument to the screen.
<?php
echo "freeCodeCamp";
NOTE: A short hand way to open the PHP tag and echo is <?=
<?= "freeCodeCamp"; ?>
The print()
function out the value of a variable or argument to the screen.
<?php
print "freeCodeCamp";
print_r
The print_r()
function writes out the value of any variable (such as an array) or argument to the screen, unlike the echo or print functions which are more limited.
<?php
$freecodecamp = "freeCodeCamp";
print_r($freecodecamp);
