'Problem with PHP parsing URL encoding'

Parse the passed JSON value through $GLOBALS["HTTP_RAW_POST_DATA"] and find that "is escaped to %22 by the browser.

It turns out that the content obtained by $_SERVER['QUERY_STRING'] and $GLOBALS["HTTP_RAW_POST_DATA"] They are all contents without result decoding.

$postStr = str_replace("%22", """, $postStr);

Just replace.

The above introduces the "problem" of PHP parsing URL encoding, including aspects of the content. I hope it will be helpful to friends who are interested in PHP tutorials.
