## 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
|
||
|
|
<?php
|
||
|
|
echo "freeCodeCamp";
|
||
|
|
```
|
||
|
|
NOTE: A short hand way to open the PHP tag and echo is <?=
|
||
|
|
```
|
||
|
|
<?= "freeCodeCamp"; ?>
|
||
|
|
```
|
||
|
|
|
||
|
|
### print
|
||
|
|
The `print()` function out the value of a variable or argument to the screen.
|
||
|
|
```PHP
|
||
|
|
<?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
|
||
|
|
<?php
|
||
|
|
$freecodecamp = "freeCodeCamp";
|
||
|
|
print_r($freecodecamp);
|
||
|
|
```
|
||
|
|
|
||
