How Many Ways to Include Array Elements in Double-Quoted Strings?

A

There are 2 formats to include array elements in double-quoted strings:

"part 1 $array[key] part 2" - This is called simple format. In this format, you can not specify the element key in quotes.
"part 1 {$array['key']} part 2" - This is called complex format. In this format, the array element expression is specified in the same way as in a normal statement.

Here is a PHP script example of different ways to include variables in double-quoted strings:

<?php 
$fruits = array('strawberry' => 'red', 'banana' => 'yellow');
echo "A banana is $fruits[banana].\n";
echo "A banana is {$fruits['banana']}.\n";
?>

This script will print:

A banana is yellow.
A banana is yellow.

"A banana is $fruits['banana'].\n" will give you a syntax error.
