PHP โ Essential Concepts ๐
1๏ธโฃ Basics of PHP
Server-Side Scripting โ PHP runs on the server, generating dynamic web pages.
Syntax & Variables โ $variable_name = "value";
Data Types โ Strings, Integers, Floats, Booleans, Arrays, Objects.
Operators โ Arithmetic (+, -, *, /), Comparison (==, !=), Logical (&&, ||).
2๏ธโฃ Control Structures
Conditional Statements โ if, else, elseif, switch.
Loops โ for, while, do-while, foreach.
Functions โ Define reusable blocks of code (function myFunction() {}).
3๏ธโฃ Working with Forms
Handling Form Data โ $_GET and $_POST.
Validation & Sanitization โ filter_var(), htmlspecialchars().
File Uploads โ Handling $_FILES array.
4๏ธโฃ Working with Databases (MySQL & PDO)
Connecting to a Database โ mysqli_connect() or PDO.
Executing Queries โ SELECT, INSERT, UPDATE, DELETE.
Prepared Statements โ Prevent SQL injection using prepare().
5๏ธโฃ PHP and Sessions
Sessions โ Store user data across pages (session_start();).
Cookies โ Store small pieces of data on the client (setcookie();).
6๏ธโฃ Object-Oriented Programming (OOP) in PHP
Classes & Objects โ Define with class and instantiate using new.
Encapsulation โ Use public, private, protected.
Inheritance โ Extend functionality using extends.
Polymorphism & Interfaces โ Create flexible code structures.
7๏ธโฃ File Handling
Reading & Writing Files โ fopen(), fread(), fwrite().
Working with JSON & XML โ json_encode(), json_decode().
8๏ธโฃ REST APIs with PHP

๐ฐ How to become a data scientist in 2025?
๐จ๐ปโ๐ป If you want to become a data science professional, follow this path! I've prepared a complete roadmap with the best free resources where you can learn the essential skills in this field.
๐ข Step 1: Strengthen your math and statistics!
โ๏ธ The foundation of learning data science is mathematics, linear algebra, statistics, and probability. Topics you should master:
โ Linear algebra: matrices, vectors, eigenvalues.
๐ Course: MIT 18.06 Linear Algebra
โ Calculus: derivative, integral, optimization.
๐ Course: MIT Single Variable Calculus
โ Statistics and probability: Bayes' theorem, hypothesis testing.
๐ Course: Statistics 110
โโโโโ
๐ข Step 2: Learn to code.
โ๏ธ Learn Python and become proficient in coding. The most important topics you need to master are:
โ Python: Pandas, NumPy, Matplotlib libraries

SQL From Basic to Advanced level
Basic SQL is ONLY 7 commands:
- SELECT
- FROM
- WHERE (also use SQL comparison operators such as =, <=, >=, <> etc.)
- ORDER BY
- Aggregate functions such as SUM, AVERAGE, COUNT etc.
- GROUP BY
- CREATE, INSERT, DELETE, etc.
You can do all this in just one morning.
Once you know these, take the next step and learn commands like:
- LEFT JOIN
- INNER JOIN
- LIKE
- IN
- CASE WHEN
- HAVING (undertstand how it's different from GROUP BY)
- UNION ALL
This should take another day.
Once both basic and intermediate are done, start learning more advanced SQL concepts such as:
- Subqueries (when to use subqueries vs CTE?)
- CTEs (WITH AS)
- Stored Procedures
- Triggers
- Window functions (LEAD, LAG, PARTITION BY, RANK, DENSE RANK)
These can be done in a couple of days.
Learning these concepts is NOT hard at all
- what takes time is practice and knowing what command to use when. How do you master that?
- First, create a basic SQL project
- Then, work on an intermediate SQL project (search online) -
Lastly, create something advanced on SQL with many CTEs, subqueries, stored procedures and triggers etc.
This is ALL you need to become a badass in SQL, and trust me when I say this, it is not rocket science. It's just logic.
Remember that practice is the key here. It will be more clear and perfect with the continous practice
