1

Create a string with double quotes

Create a string variable called text with the value "Hello World" using double quotes.

PHP

# Create a string variable called text with the value "Hello World"
# Your code here

Use double quotes around the string and assign it to $text.

2

Add escape sequences for new line and tab

Modify the $text variable to include a new line escape sequence \n after "Hello" and a tab escape sequence \t before "World".

PHP

<?php
$text = "Hello World";
# Add \n after Hello and \t before World inside the string
# Your code here

Need a hint?

Use \n for new line and \t for tab inside the double quoted string.

3

Add escaped double quotes inside the string

Modify the $text variable to include escaped double quotes around the word World using \".

PHP

<?php
$text = "Hello\n\tWorld";
# Add escaped double quotes around World
# Your code here

Need a hint?

Use \" to include double quotes inside a double quoted string.

4

Print the string to show escape sequences

Use echo to print the $text variable so the new line, tab, and double quotes appear correctly.

PHP

<?php
$text = "Hello\n\t\"World\"";
# Print the $text variable
# Your code here

Need a hint?

Use echo $text; to display the string with escape sequences.
