2/14/2024 0 Comments Php post request![]() We are trying to create a FORM that takes Input as the Name, a request is submitted from the method POST with certain details and the data is collected by the Request Method. Let’s start by creating an HTML form and see how the Request Generates. Let us see some functioning of $_POST with some Example: Example #1 So after the URL is Hit the URL will be something like that with the POST Method: Localhost/pagename.php Examples of PHP $_POST The Post method is used for creating complex Form in HTML and to handle complex data are sent over the network. And since the Values are not visible the result cannot be book marked. The time spent by method POST is more than that of the other request that is why it has some what low performance, But it is widely used as the exposure for this is more as it supports many data types such as String, numeric, binary. _POST is an array of variable passed to script via the HTTP Post Method. The data sent by the POST Method is invisible to others and we cannot see any form of data when passed on. The data is then passed with some security protocol making the information secured and then sent to an associative array using the $_POST method. Both Binary, as well as ASCII data, can be sent of with the POST method. It doesn’t have the limit of data size to be sent in this QUERY_STRING. Once we get the encoded data it is sent to a header called QUERY_STRING. All the special characters are removed and the data is encoded. ![]() The Information is encoded using a scheme where the KEY/VALUE pairs are joined with an equal sign. ![]() The Post Method transfers the information via the Headers. When a user fills the data in a PHP form and submits the data that is sent can be collected with the _POST Method in PHP. Here $_PHP_SELF variable contains the name of self script in which it is being called.The $_POST variable collects the data from the HTML form via the POST method. The PHP $_REQUEST variable can be used to get the result from form data sent with both the GET and POST methods.Įcho "You are ". We will discuss $_COOKIE variable when we will explain about cookies. The PHP $_REQUEST variable contains the contents of both $_GET, $_POST, and $_COOKIE. It will produce the following result − The $_REQUEST variable The PHP provides $_POST associative array to access all the sent information using POST method.Įcho "You are ". By using Secure HTTP you can make sure that your information is secure. ![]() The data sent by POST method goes through HTTP header so security depends on HTTP protocol. The POST method can be used to send ASCII as well as binary data. The POST method does not have any restriction on data size to be sent. The information is encoded as described in case of GET method and put into a header called QUERY_STRING. The POST method transfers information via HTTP headers. It will produce the following result − The POST Method Try out following example by putting the source code in test.php script.Įcho "You are ". The PHP provides $_GET associative array to access all the sent information using GET method. The data sent by GET method can be accessed using QUERY_STRING environment variable. GET can't be used to send binary data, like images or word documents, to the server. Never use GET method if you have password or other sensitive information to be sent to the server. The GET method is restricted to send upto 1024 characters only. The GET method produces a long string that appears in your server logs, in the browser's Location: box. The page and the encoded information are separated by the ? character. The GET method sends the encoded user information appended to the page request. After the information is encoded it is sent to the server. Spaces are removed and replaced with the + character and any other nonalphanumeric characters are replaced with a hexadecimal values. In this scheme, name/value pairs are joined with equal signs and different pairs are separated by the ampersand. There are two ways the browser client can send information to the web server.īefore the browser sends the information, it encodes it using a scheme called URL encoding.
