Is PHP a strongly typed language?

 No. PHP is a weakly typed or loosely typed language.

This means PHP does not require to declare data types of the variable when you declare any variable like the other standard programming languages C# or Java. When you store any string value in a variable, then the data type is the string and if you store a numeric value in that same variable then the data type is an Integer.

Sample code:

$var = "Hello"; //String
$var = 10; //Integer

Class is declared using "class" keyword. Object Basic runtime entity in object oriented environment. Object belongs to only class. Object are a implementation of class. It is physical existence.
