Use PHP to receive POST data and parse json data

This article describes how to use PHP to receive POST data and json data. For more information, see The code is as follows:

$ Json_string = $ _ POST ["txt_json"];
If (ini_get ("magic_quotes_gpc") = "1 ")
{
$ Json_string = stripslashes ($ json_string );
}
$ User = json_decode ($ json_string );
Echo var_dump ($ user );
?>

In this file, first obtain the value of the POST form field txt_json in the html file, put it in the variable $ json_string, and then judge, if the current PHP is set to magic_quotes_gpc = On, that is, the passed double quotation marks will be escaped, so that the json_decode function cannot be parsed. Therefore, we need to reverse it. Then, use the json_decode function to convert the JSON text into an object, save it in the $ user variable, and finally use echo var_dump ($ user); to output the dump of the object.
