Php json decode stdclass object12/28/2023 ![]() So converting an array into stdClass at runtime will be better option. ![]() We will discuss in detail the encoding and decoding of JSON in PHP. Mostly in todays web frameworks we commonly deal with class hierarchy. In this PHP tutorial, you will learn all about JSON in PHP. ![]() These 3 ways of Converting an Array To StdClass With PHP gives better options depending upon the requirement. Instead of writing a custom function, we can use these in-built function to get the desired output and also we don’t need to worry about innermost array element as these two functions will take care of them. Print_r(json_decode(json_encode($empInfo))) So, first we’ll convert an object into a JSON string and then will convert it into an object using json_decode(). When TRUE, JSON objects will be returned as associative array s when FALSE, JSON objects will be returned as object s. Json_encode() is used to convert an Array into JSON string and json_decode() is used to convert a JSON string into an Array. Json_encode() and json_decode() are the functions especially for performing operations on JSON string. Solution 3: Using json_encode() and json_decode() Here, in the above example, we have recursively called toObject() function to check the innermost array present (if any) and then typecast it into an object. Solution 2: Using custom function 'John', So, here we can write our customize function to solve the problem. So, type juggling casts the values at the opt level keys and not the keys which are defined in a nested pattern. But what if array is multidimensional? Does above solution work? And the answer is NO.Īs we can see, an array defined inside the employment key does not get converted to a stdClass. This is the simplest solution to our problem. The JSON string has been converted to an object and we can treat it like any other object in PHP. We can now access the property of the object with object-oriented style syntax as $empInfoObj->name which will output John. Here, we defined an array $empInfo in which we defined 3 keys and associated values and in the later line we typecast our array into an object using the name of the desired type written in parentheses before the variable which is to be cast. Verwendung von jsondecode zu 'sondieren', ist vielleicht nicht der schnellste Weg. Here, point to be noted that despite generic class, stdClass is NOT the base class for objects in PHP and we can prove this using instanceof keyword. StdClass is just a generic empty class in PHP OR we can say it’s PHP’s class prototype like Object.prototype in JavaScript, Object in Java OR object in Python. Solution 3: Using json_encode() and json_decode().Solution 1: Using typecast/ Type Juggling.3 different ways to convert array to stdClass.My name is Nick Hatter and I am currently studying MEng Computer Science at the School of Electronics and Computer Science (ECS) in Southampton University. For 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. It will convert value of one data type into another data type. Using Typecast Using custom function Using jsonencode () and jsondecode () Solution 1: Using typecast/ Type Juggling Typecasting an array to a stdClass object is the easiest way to achieve. This was my first blog post for this site, so I feel an introduction is in order. 3 different ways to convert array to stdClass. Hopefully this will save you having to bang your head against a wall when you can't parse even the most simplest of JSON.įor good measure, you may well want to try this example from the php.net website:Īssuming you've fixed the problem, this should output: etc/rc.d/httpd restart depending on your distro) Save the configuration file and restart Apache (eg.Uncomment the line extension=json.so by removing the semi-colon.You will find a list of extensions which have been conveniently commented out to improve PHP performance. In the configuration file there will be a section called Dynamic Extensions.nano /etc/php/php.ini depending on distro) Most likely, you will be given this error message now: Php Fatal Error Call To Undefined Function Json_decode.Enable error messages to be shown by writing ini_set('display_errors', '1') in your PHP code.Carry on reading if you would like to know how to fix it. What will happen is you will be given no output at all. When you have first installed PHP, you may find that json_decode doesn't work.
