Single and Double Quotes in PHP

Example usage of Quotes

Single quotes: Hello. My name is $name!(single quote)

Double quotes: Hello. My name is Hemamrutha!(doublele quote)

Explanation

In PHP, single-quoted strings display most text exactly as it is written, so a variable such as $name is not replaced with its value. Everything in them is passed through AS IS.
Double-quoted strings interpret variables and special escape sequences. Will translate variables (and other) into their respected values.
