varriable in

php varriables remain as the varriable within a single quote, but in double quotes they have their values in them. We can use curly braces in double quotes for using with varriable.

Question:

Which of the following are not valid ways to embed a variable into a string?

Answer:(choose 2)

1. $a = "Value: $value->getValue()";
I am not sure about this.
2. $a = "Value: {$value}";
3. $a = 'Value: $value';
it will output Value: $value.
4. $a = "Value: $value";
5. $a = "Value: {$value['val']}";
