What is the purpose of using Auto Increment in PHP database tables?

Auto Increment in PHP database tables is used to automatically generate a unique value for each new record inserted into the table. This ensures that each record has a distinct identifier, making it easier to manage and query the data. It eliminates the need for manually assigning IDs to each record, reducing the risk of duplication or errors. 

// Example of creating a table with an auto-increment primary key in PHP
$sql = "CREATE TABLE users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(50) NOT NULL,
    email VARCHAR(50) NOT NULL
)";
