#Php json decode object to array code#

In the above program, we can see when we have declared a json_string and access any of element in array we use array in any programming language similarly, we write it with echo function and in the above code we have to observe that we have not passed asso_arr parameter in the json_decode() function so to access the element we have to write “echo $x-> Companyname ” and if we set the second parameter to “true” then we have to write “echo $x ”.

#Php json decode object to array how to#

In the below program we will see how to access an element of an array using the echo function.

Now we will see an example below having an invalid JSON format and passing this string to the json_decode() function and what error and output it will give and we will also how to print those array which can be accessed using the “echo” function in the below section. Suppose we have not set anything or not passed asso_arr parameter such as “var_dump(json_decode($json_string)) ” then this value would give us access to the property of the object in an array as shown in the below screenshot. 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. 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.
