What is $HTTP_RAW_POST_DATA??

knowj

I am currently working with another developers system which is running on a PHP4 server. I am going to be Deving on a php5 severer and the website is going to be moved to the same PHP5 server.

I have been removing all the $HTTP*VARS for the current syntax but came across $HTTP_RAW_POST_DATA which is one variable I have never encountered in 4-5 years of working with PHP.

The documentation on this is little to none with a bit of searching. Is this handled in the same way as $_POST/$HTTP_POST_VARS or does it gather other information that the standard super globals do not.

Thanks in advance.

By default $HTTP_RAW_POST_DATA is not populated if we see a known encoding. With a known encoding we decode it and populate $_POST. If you want to force $HTTP_RAW_POST_DATA to always be populated turn on always_populate_raw_post_data in php.ini

With respect to upgrading:

However, the preferred method for accessing the raw POST data is php://input.
