if any website doesn't have API, can i able to send post&get request to website and get data?
Example :
<form action="/index.php" method="post">
<input type="text" name="send" id="submit" placeholder="Enter name">
</form>
when i fill the textbox and hit enter , the output show me correct data. but when i write GET method in address bar and send request, the output show me incorrect data.
http://site1.com/index.php?send=INPUT&id=
and redirect me to :
http://site1.com/?send=INPUT&id=
can anyone explain me why? and how to send request with php to get data?
