So clearly it is creating the json just not transferring it from one page to the next. Normally, jsondecode () will return an object of \stdClass if the top level item in the JSON object is a dictionary or an indexed array if the JSON object is an array. Objects are enclosed by curly brackets: “] The jsondecode () function takes a JSON-encoded string as its first parameter and parses it into a PHP variable. Defaults to true (in contrast to the PHP native default of null ). When null, JSON objects will be returned as associative arrays or objects depending on whether JSONOBJECTASARRAY is set in the flags. In other words, a JSON object can contain one or more JSON objects.įor example, the “Contact” variable is a JSON object with the following key => value pairs: When true, JSON objects will be returned as associative arrays When false, JSON objects will be returned as objects. Numbers, Booleans and null values are not.Ī value can also be a JSON object itself, containing more nested key => values. Strings are always enclosed in double quotes (“”). Null values, like the Address variable. ![]() ![]() Boolean values (“true” or “false”), like the Admin variable.Strings, like “Alex” (the Name variable). ![]() While the keys are always strings, the values can be any of the following types: The values are the actual values of the variables identified by the keys. The keys are always strings and are always enclosed in double quotes. In the above example, the keys are “Name”, “Age”, “Admin”, “Contact” and “Tags”. More precisely, a JSON object contains a list of key => value pairs, separated by a colon. PHP 7.As you can see, a JSON object is a container for other variables. If the JSON object cannot be decoded it returns NULL Returns the value encoded in JSON in appropriate PHP type.
