Use PHP to receive post data and parse JSON data

This article is the use of PHP to receive post data and JSON data for a detailed analysis of the introduction, the need for friends to copy the Code code below:
<?php
$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, we first get 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 incoming double quotes will be escaped so that Json_ The Decode function cannot parse, so we want to invert it. Then, use the Json_decode function to convert the JSON text to an object, save it in a $user variable, and end up with the Echo var_dump ($user);
