It has array(5) which means it has 5 elements in an array. In the above code, we can are declaring a JSON variable as json_string in which we are storing the JSON format data to be converted and then this variable is passed as a parameter to json_decode() function with asso_arr set as “true” that gives it in an array format as shown in the above screenshot. In the above program, we can see when we are writing PHP code in HTML structure we start with “”. Examples of PHP json_decodeįollowing are the examples are given below: Example #1 Now let us see simple example which uses json_decode() of PHP in a HTML structure. This json_decode() function of PHP takes JSON encoded string as input and returns the value that is decoded to PHP objects which of PHP data types and if the decoding is not possible then this function returns null instead of PHP objects. Opt: this parameter is used to specify the bitmask of JSON_OBJECT_AS_ARRAY, JSON_BIGINT_AS_STRING,JSON_INVALID_UTF8_SUBSTITUTE, JSON_THROW_ON_ERROR and this also an optional parameter. Recur_depth: this parameter is used to specify the depth of the recursion and this is also an optional parameter with 512 as a default value.This parameter is optional and has false as the default value. Asso_arr: this parameter is used to specify the Boolean values that can return an associated array if the value is set to true, else returns an object if it is set to false.Json_string: this parameter is compulsory to specify the JSON encoded string for converting it into PHP objects Syntax: json_decode(json_string, asso_arr, recur_depth, opt ) In this article, json_decode() is an inbuilt function provided by PHP for converting or decoding the JSON string into PHP objects where this function takes the JSON data or string which represented as a javascript array as a parameter which is an encoded string is decoded to PHP objects or data types using this json_decode() function and the opposite is done using json_encode() function in PHP. In general, the PHP provides a function that takes a JSON string that usually represents a javascript array or object literals for converting this encoded string in JSON format to a particular PHP object data type. You can test the JSON+POST handling with cURL.In PHP the inbuilt function json_decode() function is defined as a function as it name suggest it is a function for conversion of any JSON a standard text format objects or decoding of JSON objects to PHP objects, taking a JSON string as a parameter which this function converts or decodes it and returns the encoded values which were in JSON into proper PHP objects. It makes sense that the JSON isn't handled via normal $_POST since there's really no key, per se essentially you just need the "blob" of data as a whole, which is provided by php://input. From there you use json_decode to turn the JSON string into a workable object/array. $json_str = file_get_contents('php://input') įile_get_contents, which I though was only used to retrieve content from local files or traditional URLs, allows you to use the special php://input address to retrieve JSON data as a string. I had expected the data to land in $_POST but the variable was empty how the hell do I get the POST data? To get POST JSON with PHP, you use the following: Part of the authentication transaction requires Phabricator to receive a POST request that contains JSON data. Coming back to a language you haven't touched in years feels like a completely new experience you notice patterns and methods that you wouldn't have guessed of in years past. This task has thrust me back into the world of PHP, a language I haven't touched much (since version ~5.2) outside of creating WordPress themes and plugins for this blog. My recent work at Mozilla has me creating an OAuth-like authentication transaction between Bugzilla and Phabricator.
