Response and example taken of this link:

1- echo with Curly Brackets allows you to use the variable inside strings to separate the variable value of the text around it.

$verb = 'add';
echo "Present tense of this verb is $verb";

Imagine you want to add "ed" to the end of the variable without having to reset it:

echo "Past tense of this verb is $verbed";

This will generate an error, PHP will try to access the value of the variable "verbed".

But it would solve if using the following code:

echo "Past tense of this verb is {$verb}ed";

2- If $Verb is an array, an element can be accessed like this:

echo "Past tense of this verb is {$verb['past_tense']}";

3- If $Verb is an object and has a method called getPastTense() which returns a string, can be used this way:

echo "Past tense of this verb is {$verb->getPastTense()}";
