A simple example of PHP receiving post data and parsing json

php receives post data and parses json code, using php functions--stripslashes, json_decode, var_dump:

<?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);
?>

Code description: First, get the value of the POST form field txt_json in the html file, put it into the variable $json_string, and then make a judgment. If the current PHP setting is magic_quotes_gpc=On, that is, the incoming double quotes will be escaped, so the json_decode function Cannot be parsed, so it needs to be unescaped. After anti-escaping, 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 dump the object.

Attached, PHP JSON data parsing code

PHP parses JSON data code, it always knows how to parse API data in various transmission formats, including JSON, XML, etc. The following code parses the data obtained by POST from the Renren Connection website:

<?php
$json_string='{"id":1,"name":"jbxue","email":"admin@jbxue.com","interest":["wordpress","php"]} ';
$obj=json_decode($json_string);
echo $obj->name; //prints foo
echo $obj->interest[1]; //prints php
?>
