README

This is a simple PHP class that provides a wrapper around the MySQL database using the MySQLi extension. It abstracts the database connection and query execution, making it easier to interact with a MySQL database in your PHP projects.

Features

• Establishes a connection to the MySQL database using the provided credentials.
• Executes SQL queries using prepared statements, which helps prevent SQL injection attacks.
• Provides a method to execute stored procedures with parameters.
• Fetches all rows from a MySQL result set and applies an optional callback to each row.
• Automatically closes the database connection when the object is destroyed.

Installation

To install the utility, you can use Composer. Add the following to your composer.json file:

{
	"require": {
		"mohiwalla/php-mysql": "1.0.0"
	}
}

Then run:

composer install

OR just run this command directly:

composer require mohiwalla/php-mysql

Usage

Here's an example of how to use the DB class:

require __DIR__ . "/vendor/mohiwalla/php-mysql/index.php";

$con = new DB("localhost", "root", "", "shoppy");
$query = "SELECT * FROM users;";
$result = $con->query($query);

while ($row = mysqli_fetch_object($result)) {
    echo print_r($row, true);
}

Methods

__construct(string $host, string $user, string $password, string $database)

Initializes a new instance of the DB class, establishing a connection to the MySQL database using the provided host, user, password, and database name. If the connection fails, the script exits with an error message.

query(string $query, ...$values)

Executes a SQL query using a prepared statement with the given parameters. This function prepares and executes the query, handling the binding of the provided parameters to the query and returning the result object.

procedure(string $name, ...$values)

Executes a stored procedure with the given name and parameters. This function constructs a SQL query to call the stored procedure using placeholders for the parameters, then prepares and executes the query.

fetchAll($result, callable $callback = null)

Fetches all rows from a MySQL result set and applies an optional callback to each row. This method iterates over the result set, fetches each row as an associative array, optionally applies a user-defined callback to each row, and collects the rows in an array.
