Basically, single-quoted strings are plain text with virtually no special case whereas double-quoted strings have variable interpolation [e.g. echo "Hello $username";] as well as escaped sequences such as "\n" [newline.]

You can learn more about strings in PHP's manual.

There are 3 syntax used to declare strings, in PHP and -> may look similar but are totally different in their usage. => is referred to as double arrow operator. It is an assignment operator used in associative arrays to assign values to the key-value pairs when creating arrays.
