JSON stands for JavaScript Object Notation. First we need to start our xampp server then we need to load this program on browser we can see result of converted json format array values.
PHP JSON DECODE SHOWS THE SIZE OF OBJECT HOW TO
In conclusion we are able to know how to create json object in php. You can define array with any key, values it all depends on our own wish we can modify it. We can also define array with combination of more number of key and respective values.To generate json string we will use php function.

The keys are always string and enclosed in double quotes. As we know json object is a container for other variables it contains a list of key, value pairs separated by colon.It is aimed at converting the returned objects to associative arrays. So it is converted into json format and displayed converted result using echo() method. In the jsondecode function, there is a parameter known as assoc. Then we using json_encode() method and passed parameter as associative array ‘$arr’.Here we defined associative array and named this array as ‘$arr’ then we initialized some keys and respective values ("John"=>34,"Prawin"=>25,"Jazz"=>19).In php when define a variable we need to use ‘$’ symbol before variable name and we don’t need to add data types because it can automatically associates data type to the variable depending on its value.The default file extension for php files is “.php” and php statements end with ‘ ’ semicolon.A php script can be placed anywhere in the document.This method had two parameters first one is value being encoded second one is optional value is a bitmask consisting of more number of options like JSON_HEX_TAG, JSON_HEX_AMP.etc. The jsondecode() function is used to decode a JSON object into a PHP object or an associative array.

The claims in a JWT are encoded as a JSON object that is digitally signed using JSON Web Signature (JWS).
Since the JSON format is text-based format, it can easily be sent to and from a server and used as a data format by any programming language. The only thing I can think of, might be caused by the DESCRIPTION which has random data/characters that are not converting.In this tutorial we will show you the solution of PHP create json object, as we know JSON object is a syntax for storing and exchanging data. But especially if you need to decode, and re-encode json, it might be prudent to decode to objects and not arrays. Arrays may be somewhat easier to work with/transform than objects.
