These functions are jsonencode () and jsondecode (). PHP XML PHP XML Parsers PHP SimpleXML Parser PHP SimpleXML - Get PHP XML Expat PHP XML DOM We will discuss in detail the encoding and decoding of JSON in PHP. PHP jsondecode and jsonencode functions are used to decode and encode JSON object. These functions works only with UTF-8 encoded string. Decoding JSON data in PHP: It is very easy to decode JSON data in PHP. You just have to use jsondecode () function to convert JSON objects to the appropriate PHP data type. Example: By default the jsondecode () function returns an object. The json.Decoder and json.Encoder types in package encoding/json offer support for reading and writing streams, e.g. JSON is an abbreviation for JavaScript Object Notation. reads a stream of JSON objects from a Reader (strings.Reader), removes the Age field from each object, and then writes the objects to a Writer (os.Stdout). JSON is a lightweight data transfer format that is simple to understand and create. Json_decode( string, assoc, depth, options) Parameter Values Parameter PHP Examples PHP Examples PHP Compiler PHP Quiz PHP Exercises PHP Certificate PHP - AJAX AJAX Intro AJAX PHP AJAX Database AJAX XML AJAX Live Search AJAX Poll JSON, like XML, is a text-based format that is simple to write and interpret for both humans and computers but, unlike XML, JSON data. JSON_INVALID_UTF8_IGNORE, JSON_INVALID_UTF8_SUBSTITUTE, Specifies a bitmask (JSON_BIGINT_AS_STRING, Object will be converted into an associative array. Then in the inner loop, I list out the car’s properties, in this cae the make and colour or the car.Īgain I use the key/value pair, this time to name the prperty on-screen.JSON_OBJECT_AS_ARRAY, JSON_THROW_ON_ERROR)
So each item in the array get’s a link to its own page. This was done just as an example how and why you may access the key in foreach. In a hypothetical scenario, I may have pulled data from a database in such a way that the array key matches the database ID of the item. In the outer loop I access the key to add a query string to a URL. But I choose those varable names, they are not built in, they are whatever you want them to be.
I call the key $prop (my shorthand for property) as I don’t want to use $key again and cause confusion. In the inner loop I access the nested arrays. So in the outer loop I’m calling the key $key and the value (which is a nested array) $car, because it describes a car. Here you write foreach($car as $prop => $value) So the $car variable is used to grab the car property but then stores the value inside the $key variable? Seems odd. Logically, it would seem that the $car variable would hold the value which in this case would be mazda and lincoln.
Last question, in this snippet, you write ($dec as $key => $car) and then inside the foreach you use the key variable instead of the $car variable. So running stripslashes json decode whether in the first or second function returns the string as empty when saving to the db.Ĭould you elaborate as to how you can see printing out messages like the one in your post? Why it returns empty in the db after decoding it, and lastly, how would I access the data after decoding it? I tried decoding in the original function before sending the data as an argument to the second function and it returns empty in the database there as well. (It’s the same data, same format, same everything?) I find it interesting that I can save the data as a string to the db but when I simply pass the data as is in a string with the backslashes and all as an argument to another function I can’t save it to the db in the second function. I tried running this and again when I try to save $dec to the database it returns empty, also tried encoding after decoding and returns empty in the databae. How are you getting this printed information? With javascript I can use console.log($variable)
