How to use PHP to implement logistics tracking function?

With the development of the e-commerce industry, the logistics industry has gradually become an important part of the e-commerce industry. As the volume of e-commerce orders increases, logistics operations also need to follow up quickly to provide better services. The logistics tracking function is precisely one of the important means to improve the efficiency of logistics services and optimize customer experience.

In the field of e-commerce logistics, the logistics information generated by each order can be tracked at any time. From order placement to receipt, customers will want to know the logistics status at any time, and this requires the e-commerce platform to provide real-time Logistics information. Therefore, in order to improve user experience, logistics tracking function has become one of the standard features on e-commerce platforms. So, how to use PHP to implement logistics tracking function? Below, we will explain them one by one.

1. Introduction to the logistics tracking function

The logistics tracking function is one of the important services provided by the e-commerce platform to users. After the user places an order, the e-commerce platform will promptly assign a waybill number to the order and automatically enter the logistics information of the order into the system that interfaces with the logistics company. Therefore, when the user completes the payment, he can also see the order's waybill number, logistics information, and estimated arrival time. Users can check the logistics information of their orders on the e-commerce platform based on the waybill number, including delivery time, logistics status, delivery results, etc.

2. The basic process of realizing the logistics tracking function

The basic process of realizing the logistics tracking function is as follows:

1. Apply for logistics API: First, you need to apply to support logistics tracking API applications for domestic logistics companies are generally free to use. Common logistics companies such as SF Express, ZTO, and STO all provide API services.
2. Connect to Logistics API: You need to connect to Logistics API to access and obtain logistics information. Therefore, you can use the CURL, file_get_contents and other methods provided by PHP to access API information.
3. Parse API return data: After obtaining the API return data, you need to perform data analysis to extract key information. You can use the Json_decode, simplexml_load_string and other methods provided by PHP to parse the returned data.
4. Display logistics information: Finally, the parsed logistics information needs to be displayed on the web page, usually in the form of a table or list.

3. Steps to use PHP to implement logistics tracking function

1. Apply for logistics API

Applying for API can be found on the official website of the relevant logistics company , some commonly used express APIs are as follows:

(1) SF Express

SF Express provides a complete set of API development documents, address: https://open.sf-express.com /open/api-document/index.html.

(2) ZTO Express

ZTO Express provides a complete set of API development documents at the address: https://zop.zto.com/apiDoc/index.html.

(3) STO Express

STO Express provides a complete set of API development documents, address: https://www.kuaidi100.com/openapi/toc.shtml.

2. Connecting Logistics API

There are many ways to connect to the API. Here is curl as an example. The code is as follows:

$ch = curl_init() ;

curl_setopt($ch, CURLOPT_URL, $url); //$url is the API address

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$output = curl_exec($ch);

curl_close($ch);

echo $output;

3. Parsing API return data

API return data is usually in XML or JSON format and needs to be parsed to extract key information.

(1) XML format parsing code:

$xml = simplexml_load_string($output);

foreach ($xml->content->item as $item ) {

echo $item . "
";

}

(2) JSON format parsing code:

$json = json_decode( $output);

foreach ($json->content->item as $item) {

echo $item . "
";

}

4. Display logistics information

The last step is to display the logistics information, usually in the form of a table or list. For example, the following code can display logistics information on a web page:

Logistics Company	shipment number	Logistics status	Delivery Status

The above is the basic process of using PHP to implement the logistics tracking function. Implementing the logistics tracking function requires a certain understanding and practical experience of logistics API, PHP related functions, databases and other technologies. It requires familiarity with related technologies to develop A high-quality logistics tracking system can choose different solutions and methods for practice according to its own situation and actual needs.
