PHP 7.4 + MySQL 5.7 layout of the Wanhao YL codebase

For educational research only. This article reviews the Wanhao YL codebase (category: 其它源码) distributed on dajian168 as a downloadable archive. The goal is to study its PHP/MySQL architecture, third-party payment integration pattern, and the odds configuration module — not to operate it. If you are exploring how legacy lottery-style platforms are wired, this source code download is a useful reference.

Before opening the package, set the right expectation: roughly 42 PHP files sit across the app, agent, and admin layers, talking to about 11 MySQL tables. The interesting parts are not the game logic — it’s the payment gateway abstraction and how odds are mutated at runtime.

When I unzipped the archive, the project followed a pretty standard LAMP convention: a single index.php front controller, an /app directory for the user-facing client, an /agent directory for sub-account management, and a separate /admin panel reached through a non-guessable suffix path.

• Core engine: PHP 7.4, no namespace-based autoloading — files are included manually via a small bootstrap.
• Database: MySQL 5.7 with InnoDB tables; no stored procedures, business logic stays in PHP.
• Sessions: file-based, stored under /runtime/session/ with 1440-second lifetime.
• Vendor libs: a bundled /vendor folder containing a 2019-era PHPMailer 5.2.21 and a small Redis client wrapper.

Takeaway: if you intend to study this on a modern PHP 8.2 server, lower error_reporting to E_ALL & ~E_DEPRECATED first. In testing I found at least three deprecation warnings from curly-brace array access in legacy helpers — they don’t break logic but flood logs.

Third-party payment gateway: 4 channel stubs you should audit

The most reusable part of this archive is the payment abstraction. Inside /app/pay/ there are 4 driver files (pay_alipay.php, pay_wechat.php, pay_union.php, pay_bank.php) all conforming to the same 3-method interface: createOrder(), notify(), queryOrder(). This is the cleanest architecture pattern in the project.

Takeaway: before you repurpose this layer, change every MD5 signing key in the driver. There is a setting in the admin panel under System → Pay Config that is plaintext by default — wrap it with your own KMS or env loader before exposing it anywhere.

Odds modification module: 3 database tables to audit

The “odds editing” feature that gives this archive its name lives in /admin/odds/. When I traced the flow it touches exactly 3 tables: lottery_game (game metadata), lottery_odds (per-bet-type multiplier rows, default ~38 rows per game), and lottery_odds_log (audit trail of every change with admin user id and timestamp).

1. Open lottery_odds — confirm the multiplier column is DECIMAL(10,3), not FLOAT. Two rows in the seed data shipped as FLOAT and caused rounding drift in my local tests.
2. Verify lottery_odds_log has a composite index on (game_id, updated_at) — without it, history lookups degrade past ~500k rows.
3. Check that admin role permission odds_edit is bound per-user, not global. Out of the box it is global.

Takeaway: if you are doing a security review, treat any odds-change call as a financial-impact endpoint — rate-limit it, log it, and disable it from the agent role entirely.

Deployment environment (verified on a throwaway VPS)

Deploy steps I followed: import /sql/install.sql, copy /config.example.php to config.php, set APP_DEBUG=false, then bind /admin to a separate sub-domain with IP allow-list. Permissions were set to 755 on dirs and 644 on files.

Suitable project types (research scope only)

• Architecture study — a concrete example of mid-2010s PHP patterns: manual includes, no DI, file sessions.
• Payment abstraction reference — the 4-driver interface is genuinely clean and worth borrowing in a sandbox project.
• Security audit training — auditing this codebase teaches you to spot plaintext secrets, missing rate limits, and insufficient odds-change logging.
• Legacy migration baseline — if you inherit a similar system, the table map above tells you where to start the data export.

Notes before you run this code

• The bundled PHPMailer 5.2.21 has a known CVE (CVE-2016-10033 class); upgrade before any SMTP use.
• Database credentials in config.example.php are placeholders, but the admin default password is admin888 — change it on first install.
• Do not expose /agent or /admin on the public internet without IP allow-list and 2FA.

This source code download from dajian168 is best treated as a static reading assignment rather than a live deployment target.

FAQ

Q: Is the Wanhao YL package on dajian168 safe to run unmodified?

A: No. As of the 2026-08-08 review, the default admin password is weak, PHPMailer is outdated, and signing keys are plaintext. You would need at minimum: password reset, key rotation, and a PHP version pin before any controlled-environment execution.

Q: Can the odds modification feature be studied without running real bets?

A: Yes — set APP_DEBUG=true and ENABLE_LIVE_PAY=false in config.php. The odds module and audit log table remain fully interactive, so you can trace every multiplier change without moving money.

Q: Which PHP version should I use to study the payment drivers?

A: Stick to PHP 7.4.33. The payment callback handlers rely on register_shutdown_function patterns that misbehave under PHP 8.x’s stricter signature checks.
