1. Installation dependencies

Create in the project root directoryFile and add the following:

{
    "name": "yourname/stocktv-api-php",
    "description": "PHP client for StockTV API",
    "require": {
        "php": ">=7.4",
        "ext-curl": "*",
        "ext-json": "*",
        "ratchet/pawl": "^0.4.1"
    },
    "autoload": {
        "psr-4": {
            "StockTV\\": "src/"
        }
    },
    "require-dev": {
        "phpunit/phpunit": "^9.5"
    }
}

Run the following command to install the dependencies:

composer install

2. Create basic tool classes

existsrc/In, create a basic tool class to handle API requests:

<?php

namespace StockTV;

class ApiClient
{
    private $apiKey;
    private $baseUrl = "";

    public function __construct(string $apiKey)
    {
        $this->apiKey = $apiKey;
    }

    protected function get(string $endpoint, array $params = []): array
    {
        $url = $this->baseUrl . "/" . $endpoint . "?key=" . $this->apiKey;
        if (!empty($params)) {
            $url .= "&" . http_build_query($params);
        }

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        $response = curl_exec($ch);
        curl_close($ch);

        return json_decode($response, true);
    }
}

---

3. Implement the Stock API

existsrc/In order to implement stock-related APIs:

<?php

namespace StockTV;

class StockAPI extends ApiClient
{
    public function getStockList(int $countryId, int $pageSize = 10, int $page = 1): array
    {
        return $this->get("stock/stocks", [
            "countryId" => $countryId,
            "pageSize"  => $pageSize,
            "page"      => $page
        ]);
    }

    public function getIndices(int $countryId, ?string $flag = null): array
    {
        $params = ["countryId" => $countryId];
        if ($flag) {
            $params["flag"] = $flag;
        }
        return $this->get("stock/indices", $params);
    }

    public function getKline(int $pid, string $interval): array
    {
        return $this->get("stock/kline", [
            "pid"      => $pid,
            "interval" => $interval
        ]);
    }
}

4. Implement the Forex API

existsrc/, implement foreign exchange-related API:

<?php

namespace StockTV;

class ForexAPI extends ApiClient
{
    public function getCurrencyList(): array
    {
        return $this->get("market/currencyList");
    }

    public function getRealTimeRates(?string $countryType = null): array
    {
        $params = [];
        if ($countryType) {
            $params["countryType"] = $countryType;
        }
        return $this->get("market/currency", $params);
    }
}

---

5. Implement the Futures API

existsrc/, implement futures-related APIs:

<?php

namespace StockTV;

class FuturesAPI extends ApiClient
{
    public function getFuturesList(): array
    {
        return $this->get("futures/list");
    }

    public function getFuturesMarket(string $symbol): array
    {
        return $this->get("futures/querySymbol", [
            "symbol" => $symbol
        ]);
    }
}

---

6. Implementing the cryptocurrency API

existsrc/, implement cryptocurrency-related APIs:

<?php

namespace StockTV;

class CryptoAPI extends ApiClient
{
    public function getCoinInfo(): array
    {
        return $this->get("crypto/getCoinInfo");
    }

    public function getTickerPrice(string $symbols): array
    {
        return $this->get("crypto/tickerPrice", [
            "symbols" => $symbols
        ]);
    }
}

---

7. WebSocket Support

useRatchetThe library implements WebSocket connection:

<?php

require 'vendor/';

use Ratchet\Client\WebSocket;
use Ratchet\Client\Connector;
use React\EventLoop\Factory;

$loop = Factory::create();
$connector = new Connector($loop);

$apiKey = "your_api_key_here";
$wsUrl = "wss:///connect?key=" . $apiKey;

$connector($wsUrl)->then(function (WebSocket $conn) {
    $conn->on('message', function ($msg) use ($conn) {
        echo "Received: {$msg}\n";
    });

    $conn->on('close', function ($code = null, $reason = null) {
        echo "Connection closed ({$code} - {$reason})\n";
    });
}, function (\Exception $e) use ($loop) {
    echo "Could not connect: {$e->getMessage()}\n";
    $loop->stop();
});

$loop->run();

---

8. Test code

existtests/, write test code:

<?php

use PHPUnit\Framework\TestCase;
use StockTV\StockAPI;

class StockAPITest extends TestCase
{
    private $stockAPI;

    protected function setUp(): void
    {
        $this->stockAPI = new StockAPI("your_api_key_here");
    }

    public function testGetStockList(): void
    {
        $response = $this->stockAPI->getStockList(14, 10, 1);
        $this->assertArrayHasKey("data", $response);
    }
}

Run the test:

./vendor/bin/phpunit tests

---

9. Use examples

exist, write sample code:

<?php

require 'vendor/';

use StockTV\StockAPI;

$apiKey = "your_api_key_here";
$stockAPI = new StockAPI($apiKey);

try {
    $stockList = $stockAPI->getStockList(14, 10, 1);
    print_r($stockList);
} catch (Exception $e) {
    echo "Error: " . $e->getMessage();
}

---

10.

Create in the project root directorydocument:

# StockTV API PHP Client

A PHP client for accessing StockTV's global financial data APIs.

## Installation

```bash
composer install

Usage

use StockTV\StockAPI;

$apiKey = "your_api_key_here";
$stockAPI = new StockAPI($apiKey);

$stockList = $stockAPI->getStockList(14, 10, 1);
print_r($stockList);

Summarize

This PHP project provides complete support for StockTV APIs, including stocks, forex, futures and cryptocurrency data. With modular design and clear code structure, developers can easily expand and integrate into their projects.
