Examples of $_post in PHP

$_post: An array of variables passed by the HTTP POST method. is an automatic global variable.

$GLOBALS [' Http_raw_post_data ']: Always produce a variable containing the original POST data. This variable is only generated when it encounters data that does not recognize the MIME type. $HTTP _raw_post_data is not available for enctype= ' multipart/form-data ' form data.

That is to say, basically $globals[' http_raw_post_data ' is the same as $_post.

But if the POST data is not recognized by PHP, you can use $GLOBALS [' Http_raw_post_data '] to receive it, such as text/xml or soap, and so on.

• Supplemental Note: The data type recognized by PHP by default is the application/x-www.form-urlencoded standard data type.

• It's written in the handbook.
  
  Always produce a variable containing the original post data. Otherwise, this variable is only generated when it encounters data that does not recognize the MIME type. However, a better way to access the raw POST data is php://input. $HTTP _raw_post_data is not available for enctype= ' multipart/form-data ' form data.
  
  Question: $HTTP _raw_post_data = = $_post?
  
  According to the manual, the answer should be no.
  If not, what is the difference between them?

• I know the answer, as follows:
  
  The raw/uninterpreted HTTP postinformation can be accessed with:
  $GLOBALS [' Http_raw_post_data ']
  This was useful in cases where thepost content-type was not something PHP understands (such astext/xml).
  
  In other words, basically $globals[' http_raw_post_data ' and $_post are the same. However, if the POST data is not recognized by PHP, you can use $globals[' http_raw_post_data ' to receive it, such as text/xml or soap, and so on.
  
  PHP Default recognized data type is the application/x-www.form-urlencoded standard data type
  
  With the Content-type=text/xml type, submit an XML document content to the PHP server, how to get this post data.
  
  The raw/uninterpreted HTTP postinformation can be accessed with: $GLOBALS [' http_raw_post_data ']this are useful in cases w Here the post Content-type is Notsomething PHP understands (such as Text/xml).
  
  Since PHP only recognizes the application/x-www.form-urlencoded standard data type by default, the contents of the type such as text/xml cannot be parsed into the $_post array, so the prototype is retained and given to $globals[' Http_raw_ Post_data '] to receive.
  
  There is also a php://input that can be implemented with this function
  
  Php://input allows the raw data to be read from the POST. Compared to $http_raw_post_data, it brings less pressure to memory and does not require any special php.ini settings. Php://input cannot be used for enctype= "Multipart/form-data".
