Answer Posted / Varun Yadav
PHP has three scope levels: Global, Function, and Local/Private.
- Global scope: Variables declared outside of any function have global scope and can be accessed from anywhere within your script.
- Function scope: Variables declared inside a function are only available within that function.
- Local/Private scope (from PHP 5.3 onwards): Use the keyword 'private' to create variables with local scope, which are accessible only within the same class.
