Like its decoding counterpart, json_encode() accepts $flags and $depth parameters. PHP scalar types map directly into JSON with no transformation. PHP objects and associative arrays will become JSON objects containing all the enumerable property/key-value pairs of the input value. ![]() Data types are automatically handled to ensure they have an appropriate mapping in the generated JSON. PHP accepts any value as $value, except for resources. You’ve no way of knowing whether the null return value is due to the JSON containing null, or because the JSON was malformed and couldn’t be parsed. This presents an issue because an isolated null is a valid JSON string. Handling Parsing Errorsīy default, json_decode() will return null when it’s passed an invalid JSON string. Php json decode stdclass object manual#These are described in detail within the PHP manual and allow you to define how specific data types should be handled. The $flags parameter accepts a bitmask of optional flags that alter the parsing behaviour. You’ll get null if the JSON nests deeper than the set level – no attempt will be made to parse the data. The $depth parameter lets you control the maximum nesting level to parse down to. If you’d rather receive an associative array, pass true to the $associative parameter of json_decode(). Our new object will have a property foo with the value of bar. We’ll work with which decodes to an instance of PHP’s generic stdClass. I will not delve into all-out explaining what Reflection in programming is, but in simple terms, it is a set of built in methods that allow a programmer to find out details about the structure of a Class.The simplest invocation is to pass a JSON string with no other arguments. My senior colleague Boris Ćeranić told me that he is not 101% certain of the details, but had explained to me in brief what PHP Reflection API is, and how vendors implement it under the hood in order to seem smarter than they are. That kind of information can only be found on author blogposts, or by asking someone smarter than yourself. It seems that we are able to create silly (or awful) hacks around any possible problem, but when someone is searching for a genuinely smart and advanced way to solve a problem, S/O is dead. I am eternally grateful to all the people who wrote on Stack Overflow and various forums, but i cannot make peace with the obvious fact that as soon as you get interested in how something works under the hood, there is no one around. The last time i felt this hopeless and angry at myself and Stack Overflow was a year ago when i researched for two days on how exactly iOS native scroll implemented gravity under the hood. Yes i am aware that sometimes it is necessary to play dirty like that, but come on, if you are willing to write a 1000 character answer, why not use the same amount of time to find a better way of doing it? After a unserialize, you have your Object. Php json decode stdclass object verification#While we do manually transform data received from the client via form submit or API, we do it for validation and verification purposes, on the other hand unserializing data received from the DB is usually performed by the ORM itself, behind closed curtains.įor example, a bunch of people were willing to create a stdClass out of the JSON, and then serialize this stdClass into plain text while performing a brute-force regex replacement of Class name. Transform everything on input and output only, and always work with valid state objects, never with anonymous arrays. While no project is the same, most of them did solve this in a similar manner - and suddenly it made perfect sense: I decided i am not smart enough to solve this mess i made on my own, which got me to thinking about how this is handled on some large-scale projects i have worked on. Php json decode stdclass object code#4 Services, 1 Provider, 1 transformer and 2 endpoints… Let the games begin.Ī hour into it, i realized that i have 4 transformers, which are used basically all over the place, and that most of my code is not the logic behind caching anymore, but a series of silly transformations, and guesses whether something is an object or an array, or in some instances a stdClass. The project was OO based, with an MVC model similar to an extremely simplified Symfony structure. The system was really simple as you might guess, but since calls to servers are expensive in the case of Instagram API, i created a basic local cache. I was working on a cute little project which uses the public guest Instagram API to showcase all posts from the client’s page. ![]()
