The difference between post and get in php

POST and GET are two HTTP methods in PHP, used to submit data to the server. The main difference is: POST hides the data in the request body, while GET appends the data to the request URL. Additionally, POST is more suitable for transmitting large or sensitive data, is not limited by URL length, is more secure (data hiding), and is generally not idempotent. GET is suitable for transmitting small amounts or public data, is limited by URL length, is less secure (data disclosure), and is usually idempotent.

The difference between POST and GET methods in PHP

Direct answer:
POST and GET are two HTTP methods used in PHP to submit data to the server. The main differences are:

• POST: Data is sent via the HTTP request body, hidden within the request.
• GET: Data is appended to the requested URL and is publicly visible.

Detailed expansion:

1. Data transmission

• POST:Data is transmitted through the request body and will not be displayed in the URL. It is safer and suitable for transmitting large amounts of or sensitive data.
• GET: The data is embedded in the URL and will be displayed publicly. It is suitable for transmitting small amounts of data or data that can be exposed in the URL.

2. URL length

• POST: is not subject to URL length restrictions because the data is not included in the URL.
• GET: Limited by URL length, usually suitable for shorter data transfers.

3. Security

• POST: is more secure because the data is hidden in the request and will not be exposed Browser history or network sniffing.
• GET: Not very secure as the data is publicly visible in the URL and can be easily captured by a network sniffer or browser history.

4. Caching

• POST:The submitted data will not be cached by the browser because each request only one.
• GET: The submitted data can be cached by the browser because requests with the same parameters can be reused.

5. Idempotence

• POST: is usually not idempotent, which means executing the same thing multiple times The request will only produce an effect once.
• GET: is usually idempotent, meaning executing the same request multiple times will produce the same result.

Other differences:

• POST is usually used to submit form data, while GET is usually used to get information from the server.
• POST requests are more suitable for processing large amounts of data, while GET requests are better for processing small amounts of data.
• POST requests are asynchronous, while GET requests are synchronous.
