1.  PHP

How to pass data from one PHP page to another PHP page?

PHP has two methods “post” and  “get” to pass data to another page.

Example –  1

Send data to one to another page using POST

HTML PAGE

OUTPUT

Your start.php page for display data looks like this.

start.php

When a user clicks on submit button, data is posted on start.php with the HTTP POST method.
Output

Welcome Peter
Your email address is peter@example.com

 

Example –  2

Send data to one to another page using GET

Your start_get.php page for display data look like this.

start_get.php

When a user clicks on submit button data is posted on start_get.php with the HTTP GET method.

So both POST and GET method send data to another page but main question is when we use GET and POST  method ?

When to use GET?

Information sent from a form with the GET method is visible to everyone (all variable names and values are displayed in the URL). GET also has limits on the amount of information to send. The limitation is about 2000 characters. However, because the variables are displayed in the URL, it is possible to bookmark the page. This can be useful in some cases.

GET may be used for sending non-sensitive data.

Note: GET should NEVER be used for sending passwords or other sensitive information!

When to use POST?

Information sent from a form with the POST method is invisible to others (all names/values are embedded within the body of the HTTP request) and has no limits on the amount of information to send.

Moreover POST supports advanced functionality such as support for multi-part binary input while uploading files to server.

However, because the variables are not displayed in the URL, it is not possible to bookmark the page.

Developers prefer POST for sending form data.

Extend the power / Other ideas

• While you are at it, might as well compress the CSS with PHP.
• Theoretically you could pull the user agent and attempt to do browser-specific CSS, but that is littered with problems and not recommended.
• Pull the date/time, and perhaps change some stuff on your site for the different seasons or time of day.
• Generate a random number, test the result, use it to set a random background image on your header.
