Before setting up CashMan H.A., verify that your server or local development environment satisfies all of the following prerequisites. The platform is built on PHP 8.1 with an MVC architecture and relies on a MySQL-compatible database for its 21 tables, stored procedures, triggers, views, and scheduled events. Meeting every requirement listed below ensures the application boots correctly and all features — including automated email notifications, loan processing, and savings account transfers — work as expected.

​
Server Requirements

PHP 8.1+

CashMan H.A. requires PHP version 8.1 or later. Older PHP versions are not supported.

MySQL or MariaDB

A MySQL-compatible database server is required. The application has been tested with MariaDB 10.4.24.

Apache or Nginx

Any standard web server capable of serving PHP applications. Apache with mod_rewrite or Nginx with a compatible rewrite rule is recommended.

Composer

PHP dependency manager used to install the router and number-formatting libraries. Install from getcomposer.org.

​
Required PHP Extensions

The following PHP extensions must be enabled in your php.ini before running the application:
ExtensionPurpose
mysqliPrimary database driver — all eight MySQLi connections (one primary and seven auxiliary) use this extension
mbstringMultibyte string handling for name and text fields
opensslRequired by PHPMailer for SMTP TLS/SSL connections
fileinfoUsed for file-type validation when handling uploads and PDF generation

​
Composer Dependencies

The CashManHA/composer.json declares two runtime dependencies that are installed via composer install: 
{
    "require": {
        "bramus/router": "~1.6",
        "luecano/numero-a-letras": "^3.0"
    }
}
PackageVersionPurpose
bramus/router~1.6Lightweight PHP router that handles all MVC route definitions
luecano/numero-a-letras^3.0Converts numeric amounts to written words (used in loan contracts and PDF receipts)

​
Development Tools

For local development, the project is pre-configured to send transactional emails (password recovery codes, transfer security codes, credential update confirmations) through Papercut SMTP — a local SMTP sink that captures outgoing mail without delivering it. You are free to substitute any other local SMTP tool (e.g., Mailtrap) or a real SMTP provider for production deployments. See the Configuration page for the full PHPMailer settings reference.
The default server port hardcoded throughout the codebase is 90 (http://localhost:90/). If your web server listens on a different port (e.g., the standard port 80), you must update the $UrlGlobal variable and the CSS import URLs before the application will load styles or process redirects correctly. See the Installation guide for the exact files and lines to change.
