What is the difference between == and === in PHP

In PHP, the difference between == and === is fundamental to understanding how comparison works in the language.

== is known as the equality operator. It checks if two values are equal after type juggling, which means it will convert the types of the values if they are different before comparing them.

=== is known as the identity operator. It checks if two values are equal and also if they are of the same type, meaning no type conversion will occur.

Example:
