GET Method in PHP vs. POST Method in PHP: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Published on March 2, 2024
GET Method in PHP transmits data via URL, suitable for non-sensitive data retrieval. POST Method in PHP sends data through HTTP request body, used for secure data transmission.

Key Differences

GET Method in PHP appends data to the URL, visible and limited in length. POST Method in PHP sends data in the request body, hidden from the URL and more secure.
GET Method is more efficient for data that doesn't require security, like query strings in search. POST Method is better for transferring sensitive data, like user passwords.
GET requests can be bookmarked and cached, making them suitable for repeat visits. POST requests cannot be bookmarked and don't remain in the browser history.
GET Method has a size limitation, constrained by the URL length. POST Method allows for larger data sizes, not limited by URL constraints.
GET Method is simpler for data retrieval, but less secure. POST Method offers more security for data transmission, but is slightly more complex.

Using GET, the page's URL displayed all the query parameters.

POST Method in PHP

More secure than GET, suitable for sensitive data.
For password transmission, POST was the preferred method due to its security.


When should you use the POST method in PHP?

For sending sensitive or large amounts of data securely.

What is the main use of the GET method in PHP?

For retrieving data where security is not a primary concern.

Can GET requests be cached?

Yes, GET requests can be cached and bookmarked.

Is data visible in the URL with GET?

Yes, GET appends data to the URL, making it visible.

What's the data size limit for GET?

It's limited by URL length, which varies by browser.

Are POST requests cached?

No, POST requests aren't cached and can't be bookmarked.

Does POST method expose data in the URL?

No, POST sends data in the HTTP request body, hidden from the URL.

Why is POST preferred for sensitive data?

Because it transmits data within the HTTP request body, enhancing security.

Are there size limitations for POST?

POST can handle much larger data sizes compared to GET.

Is GET more efficient than POST?

GET is simpler and faster for small, non-sensitive data retrieval.

How do GET and POST affect server load?

POST requires slightly more processing, potentially increasing server load.

Can GET requests modify data on the server?

They can, but it's a practice against web standards and security.

Can GET method be used for form submission?

It can be used, but it's not recommended for sensitive data.

Is it possible to send binary data using GET?

No, GET is unsuitable for binary data, which POST can handle.

Is POST suitable for search queries?

It's less common for search queries due to its no-cache nature.

How do browsers handle GET and POST differently?
