The stack is a storage device that is used to store information in the manner of LIFO.LIFO stands for Last In First Out. The stack is a collection of objects. The Stack Pointer is a pointer that is used to represent the highest element of the stack and represented as SP. Stack has several applications in computer programming.

Stack has two operations:-

POP: POP operation is used to remove an item from the stack. Pop operations are used to retrieve an item that is present at the top of the stack.

PUSH: PUSH operation is an insertion operation that is used to store or insert an element at the top of the stack.

When an element is removed or inserted, the same operations will be performed only at the top element of the stack. When the top element is empty which is represented by MAXTERM then this is the condition of UNDERFLOW. And when the Maxterm is having an element then also we have to add one more element then the top is shifted towards upwards and this condition is known as OVERFLOW of the stack.

POP operation decreases the stack depth or length and PUSH operation increases the stack length. FIFO stack ensures that the data is retrieved in the same order in which it is entered. A stack is a recursive data structure.

Structural definition of a Stack:
* A stack is either empty.
* Stack has the top element on which PUSH & POP operations are performed.
* Stack has similar data types object list in an ordered format.
* Stack size is not fixed. It can be variable.
* Stack doesn't consume a fixed amount of memory.

What is the core difference between M.Phil and PhD ?

M.phil is an intermediate degree between MS and Ph.D. We can take advantage of both in one knowledge bundle of M.phil. Most M.phil programs are funded like a Ph.D. in which we also get a stipend. Your study totally depends on the thesis. Industrial opportunity is almost equal in both fields. M.phil is less advanced qualification than Ph.D. M.phil dissertation is normally shorter than a Ph.D. thesis.

Master of Philosophy is a master's program for research work in advance manner. Ph.D. stands for the toppers degree awarded by the university. Ph.D. is detailed research on any topic. The best of both of them are Ph.D. as it is very good in all aspects of students. Ph.D. is a  doctorate degree as the name suggest and it is basically for those students who have an interest in academics a lot.

M.phil's degree is not necessarily a researched degree. but Ph.D. is must be having research. Both degrees are best but far from both the degrees are similar. M.phil's degree leads to a master's degree and a Ph.D. degree leads to a doctorate degree. M.phil is a 1-2 year duration degree but Ph.D. is at least 3-4 year duration and many more.

After Masters and before Ph.D., we can do M.phil, but Ph.D. can do only after Masters, after bachelors in some cases. M.phil does not include any kind of training under experienced teachers but in Ph.D. we can do training under the guidance of experienced teachers. In Ph.D., the students get stipend through which they can not suffer financially. 

Nowadays many people want to step up higher in their career and this is possible only with good qualifications. Therefore both degrees have their own importance bu in comparison of values then Ph.D. is having higher importance instead of M.phil from an academic point of view.

Python: Python is a high level understood/explained and object-oriented programming language that huge library support and is used for developing standalone programs and scripting sets of computer instructions for different domains. It was created by Guido Van Rossum and released its first version in the year 1990.

PHP: Hypertext Preprocessor invented in the year of 1995 also known as PHP, is a server-side scripting language. It is used for creating energetic/changing HTML content over the web. It is popularly used for creating XML documents, Flash animations, graphics, PDF files and much more.

Ease Of Use:-

Python is a powerful, portable, open-source and is (compared to other things) easy to learn and fun to use. It has many features that other programming languages do not support. The set of rules for forming language is simpler and code is more readable in Python compared to other programming languages like PHP, C, and C++.
PHP is not used for general-purpose programming and is only used for creating energetic/changing web content with HTML. The only reason to stick with PHP is its ease of use.

PHP vs PYTHON:-

Learning Python is better than PHP in a long term project. PHP has a low learning curve, it is easy to get started with PHP.
(solid basic structure on which bigger things can be built).Compare to PHP, Python has a lower number of solid basic structures on which bigger things can be built. Popular ones are Django, Flask.PHP has a huge number of (solid basic structure on which bigger things can be built). Popular ones are Laravel, Slim.

The set of rules for forming language i.e. Syntax is easy to remember almost the same as human language. The syntax is a little bit unusual/amazing compare to Python, it has a wide range of common ways of putting a name on something. Key Features is having less line no of code, Fast use/military service and energetic/changing typing. Open Source and easy use/military service.Language type. It is a general-purpose programing language. It is a web development programing language. Popular Field is the Machine Learning, Data Science, (not made by nature/fake) Intelligence and Automation job. Choice of language in web development. Compare to PHP, Python is more easy to maintain. A little bit difficult to maintain.

Popularity Pace:-

After 2016 Python's (quality of being liked a lot or done a lot) is increasing quickly. At the same time PHP losing its (quality of being liked a lot or done a lot) on StackOverflow.

Community Support:-

Python has grown in the field of CGI scripting and in few years it has become one of the most widely used programming languages for Web Development.
Whereas web scripting is new in PHP. Though PHP is a powerful programming language when it was (at first/before other things happened) released, it would provide the same extensibility features.

End/end result:-

Both PHP and Python without any doubt are the most preferred programming languages for backend web development, but their own distinguishing points. PHP is based on object-oriented programming whereas Python is both object-oriented and procedure-oriented programming. Python is a general-purpose programming language used for backend web development. On the other hand, PHP is not designed for general-purpose programming it is only used for backend web development. The only reason for sticking with PHP is its ease of use and strength and health.
