Constants In PHP : Samee Articles

Sample 1 : What is Constant in PHP?

Constant is a identifier for a simple value.
The Value can not be changed during the script.
Value starts with letter or underscore, never with dollar sign "$".
It starts with "define."
Constant is default Case Sensitive.

Sample 2 : Constant Example in PHP

My Name is Samee Ullah Feroz.

Sample 3 : Constant Example in PHP

My Nick Name is Sherri Bhai.
