So what really happens when someone say 'new' in PHP
I believe in C/Java, when new is called, memory is allocated for each instance variables that are needed for an object? (correct me if i am wrong)
Is this the same with PHP?

The new keyword is used to create an object from a class.
$this is a reserved keyword in PHP that refers to the calling object. It is usually the object to which the method belongs, but possibly another object if the method is called statically from the context of a secondary object. This keyword is only applicable to internal methods.
class ¶ Basic class definitions begin with the keyword class , followed by a class name, followed by a pair of curly braces which enclose the definitions of the properties and methods belonging to the class. The class name can be any valid label, provided it is not a PHP reserved word.
Classes are nothing without objects! We can create multiple objects from a class. Each object has all the properties and methods defined in the class, but they will have different property values. Objects of a class is created using the new keyword.
When you use $var = new Class
$var is associated with this created zval container.1Definition of what's a zval container.

The easiest way would be to check it for yourself using memory_get_usage()
echo memory_get_usage();
$obj1 = new obj1;
$obj2 = new obj2;
$obj3 = new obj3;
echo memory_get_usage();
Same is the case with PHP.
