PHP $_REQUEST - What is the use of the $_REQUEST variable in PHP

  • PHP $_REQUEST is a PHP super global variable which is used to collect data after submitting an HTML form.
  • The example below shows a form with an input field and a submit button. When a user submits the data by clicking on "Submit", the form data is sent to the file specified in the action attribute of the <form> tag.
  • In this example, we point to this file itself for processing form data. If you wish to use another PHP file to process form data, replace that with the filename of your choice. Then, we can use the super global variable $_REQUEST to collect the value of the input field:

Sample Code

    // collect value of input field
    $name = htmlspecialchars($_REQUEST['fname']);
    if (empty($name)) {
        echo "Name is empty";
    } else {
        echo $name;
<!DOCTYPE html>
<form method="post">
  Name: <input type="text" name="fname">
  <input type="submit">
