How to Send cURL Requests in PHP for API Integration

When it comes to working with APIs in PHP, one of the essential tasks is sending HTTP requests. If you're looking to access data from a service like Nobitex through its API, you're likely wondering how to do it effectively using cURL in PHP. In this guide, we will break down the process of sending cURL requests with a practical example.

Understanding the Problem

You might come across scenarios where you need to retrieve data from an API endpoint, such as https://api.nobitex.ir/v2/orderbook/B.... This URL is designed to provide the order book information for the BTC/USDT pair – a useful feature for developers working with cryptocurrencies. Your goal is to make this request using PHP or Laravel and fetch the results.

Solution: Sending a cURL Request in PHP

To send a cURL request, PHP offers a built-in library that allows for seamless communication with various APIs. Below, we've crafted a reusable function, call_url_service_curl, that you can utilize to fetch data from any given URL.

Step-by-Step Guide to Using cURL in PHP

1. Create a cURL Function

Here's a concise function that initializes a cURL session and executes the request:

Explanation of cURL Options

CURLOPT_URL: This option sets the URL to which you want to send a request.

CURLOPT_RETURNTRANSFER: When set to true, it returns the result as a string instead of outputting it directly.

CURLOPT_SSL_VERIFYHOST and CURLOPT_SSL_VERIFYPEER: These options are important for SSL verification; they can be disabled if you want to bypass SSL checks (not recommended for production).

CURLOPT_TIMEOUT: This specifies the maximum time in seconds the request is allowed to take.

2. Call the Function and Capture the Response

Once you've defined your function, you can easily make a request to the Nobitex endpoint. Here’s how you would do it:
