![]() Also, the syntax and examples helped us to understand much precisely the function. We also saw the internal working and the advantages of having the type of data which we are defining for various programming purpose. From various example and classification we tried to understand how the $_POST function works in PHP and what are is use in the programming level. We can use conditional statements also with this method.įrom the above article, we saw the use of Function $_POST in PHP. We can use the isset function to check whether the value for this variable has been set or not. Simple POST Request to get the Address and City So the Output for this will be something like: If any condition is there that is checked or else the data is collected. Here the htmlspecialchars($Request) takes the value of Input Field and checks whether any condition is given over there or not. 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 Localhost/pagename.php Examples of PHP $_POST So after the URL is Hit the URL will be something like that with the POST Method: 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. The $_POST variable collects the data from the HTML form via the POST method.
