Answer 1

You can pass a variable via the GET method:

if($result) {
  header("Location: view.php?search={$search}"); 
} else {
  echo "not found"; 
}

And then in your destination view.php you can access it like this:

$search = $_GET['search'];

Answer 2

You have to write ? after view.php and then the parameters like this view.php?parameter1=value .

To access to those parameters in your destination page you have to use this command $_GET["parameter1"]

The GET method sends the encoded user information appended to the page request. The page and the encoded information are separated by the ? character.

• http://www.test.com/index.htm?name1=value1&name2=value2 The GET method produces a long string that appears in your server logs, in the browser's Location: box.

• The GET method is restricted to send upto 1024 characters only.

• Never use GET method if you have password or other sensitive information to be sent to the server.

• GET can't be used to send binary data, like images or word documents, to the server.

• The data sent by GET method can be accessed using QUERY_STRING environment variable.

• The PHP provides $_GET associative array to access all the sent information using GET method.
