Our first example is to find all people who owns a 'Tesla' from our sample JSON.
#Php json decode as object how to#
Now we learn how to search a nested JSON for a specific value. While most decoders will accept these values as valid JSON, some may not, as the specification is ambiguous on this point. So far, we have seen how to access all objects at a particular level. Like the reference JSON encoder, jsonencode () will generate JSON that is a simple value (that is, neither an object nor an array) if given a string, int, float or bool as an input value. Here is another example to print the number of cars each person has.Įcho( $elem.": ".count($elem)) To print all the names and corresponding cars. If you have an array inside a nested JSON object then use two foreach loops to access the inner array element. To print all the names and corresponding favourite colour.Įcho( $elem." - ".$elem ) You can access this inner JSON object just as you access a multidimensional associative array. For each person, there is a key named favourite whose value is another JSON object. In our example JSON, there are three JSON objects each corresponding to the details about a person. The value of a JSON can be another JSON object. When null, JSON objects will be returned as. When true, JSON objects will be returned as associative array s when false, JSON objects will be returned as object s. PHP implements a superset of JSON as specified in the original RFC 7159.
#Php json decode as object install#
If you have the same problem, try to install separated php-json module: yum install php-json Hope this helps. For example, to print all the name and id numbers from our example JSON document:Īccessing Nested objects inside a JSON array This function only works with UTF-8 encoded strings. On some PHP7+ systems phpjson functions can be undefined (i faced it on Oracle Linux Enterprice with php 7.4 installed from REMI repository). To access the objects inside a JSON array, the simplest and easiest method is to use a foreach loop to iterate through the array elements and fetch the data that you need. Note that the second argument in the json_decode function is set to true so that the objects returned will be associative arrays.įor more details on parsing JSON in PHP, read How to parse JSON in PHP Accessing objects inside a JSON array $json_string = file_get_contents($filepath) Firstly read the contents of the text file into a string variable using the file_get_contents() function and then use json_decode() function to convert the JSON string to a PHP variable. "favourite": Ĭonsider that our example JSON is stored in a file named "persons.txt". Let's look at some examples for accessing data a nested JSON document like below. Those are, jsonencode() jsondecode() In this article, we are going to learn about these functions with suitable examples. PHP provides built-in functions to perform these two operations. In this article, we are going to see how to encode and decode JSON using PHP. One method is to use recursion just like you access data from a nested array or tree data structure. JSON encode decode is one of the most frequently required operations. JSON objects are key-value pairs and there are different methods you can use to access JSON objects from a nested JSON document. A JSON document can have JSON objects nested inside other JSON objects. jsonDecoded jsondecode(jsonEncoded, true) vardump(jsonDecoded, 'decoded with true switch') Output: with arrays rather than objects.
