Try this.

Using MySQL with PHPDesktop Installer

To bundle MySQL with your PHPDesktop application and create a standalone installer, follow these steps:

Method 1: Bundling MySQL Server with Your App

1. Prepare MySQL Files

• Download the MySQL Windows ZIP Archive from MySQL website
• Extract it to your PHPDesktop project folder (e.g., mysql/ directory)

2. Configure MySQL for Portable Use

Create a my.ini file in your MySQL directory with portable settings:

[mysqld]
port=3307
datadir=./data
basedir=.

3. Add Startup Scripts

Create a PHP script to manage MySQL (e.g., start_mysql.php):

<?php
function start_mysql() {
$mysql_path = __DIR__.'/mysql/bin/mysqld.exe';
$command = '"'.$mysql_path.'" --defaults-file="'.__DIR__.'/mysql/my.ini" --standalone';
pclose(popen('start /B '. $command, 'r'));
}

function stop_mysql() {
exec(__DIR__.'/mysql/bin/mysqladmin.exe -u root shutdown');
}
?>

4. Modify Your Main Application

In your main PHP file (e.g., index.php):

<?php
require_once 'start_mysql.php';
start_mysql();

// Database connection
$db = new mysqli('localhost:3307', 'root', '', 'your_db');

// Register shutdown function
register_shutdown_function('stop_mysql');
?>

Method 2: Using PHPDesktop Installer with MySQL

1. Create Installation Script

Add this to your installer script (NSIS/InnoSetup):

[Files]
Source: "mysql\*" DestDir: "{app}\mysql" Flags: recursesubdirs

2. Add MySQL Initialization

Include this in your installer:

[Run]
Filename: "{app}\mysql\bin\mysqld.exe" Parameters: "--install" Flags: runhidden

3. Create Database Setup

Add a PHP script that runs on first launch:

<?php
if (!file_exists('db_initialized.flag')) {
$connection = new mysqli('localhost:3307', 'root', '');
$connection->query("CREATE DATABASE IF NOT EXISTS myapp_db");
file_put_contents('db_initialized.flag', '1');
}
?>

Method 3: Using Embedded MySQL Alternative (MariaDB)

For a lighter solution, consider using MariaDB embedded:

1. Download MariaDB Embedded
2. Include in your project
3. Use similar connection approach as above

Important Considerations

1. Port Selection: Use a non-standard port (like 3307) to avoid conflicts
2. Data Persistence: Store MySQL data in AppData for proper installation
3. Firewall: Your installer may need to configure firewall exceptions
4. 32/64-bit: Match your MySQL version with PHPDesktop architecture
