Do you think your SQL database is secure from instant destruction? Yes, instant destruction because I am talking about SQL injection. It is a combination of two words that is: SQL + injection. Here, the injection doesn’t mean the medical terminology. You always have to take care of the SQL injection In PHP while writing any SQL query. The attackers may inject some additional string or character that may break down your entire flow. So, this is very terrifying if someone will break your code. In this post, I am going to explain to you about SQL Injection attack with examples. If you won’t prevent the SQL injection vulnerability then you may lose the data. Even data can be altered or dropped out from the database. Also, I will show you the way of SQL injection prevention. So, stay head up with this post, and let’s dive into it.

What is SQL Injection?

Before taking any example, firstly, let’s know about it. This is a code injection technique used to attack a data-driven application. In this type of attack, the malicious SQL statements are inserted into the database table. This will alter your SQL query and will perform some unwanted operations that you cannot imagine. The SQL injection is mostly known as an attack vector for websites but can be used to attack any type of SQL database.

In this type of attack, the attacker can guess the table name or a kind of parameters of the SQL query. This is a very old technique in the terms of Web Development.
