Description:
------------
On HTTP PUT and PATCH Methods all PHP file methods can read php://input just one time.
In the method post 2 times the value appears as expected, but the put and patch methods returns only one time.

Test script:
---------------
<?php 
var_dump(file_get_contents('php://input'));
var_dump(file_get_contents('php://input'));
?>

Send DATA using HTTP POST and after HTTP PUT or PATCH.




Actual result:
--------------
curl -X POST -H "Content-Type: application/x-www-form-urlencoded" -d 'var1=val2&var2=val2' 'http://localhost/testmethod.php'
result:
string(19) "var1=val2&var2=val2"
string(19) "var1=val2&var2=val2"

curl -X PUT -H "Content-Type: application/x-www-form-urlencoded" -d 'var1=val2&var2=val2' 'http://localhost/testmethod.php'
