Include keyword allows to use the piece of code in some external file, into your existing code. Let’s go through them one by one! What is the difference between include and require in PHP? include Logically, they do the same thing but are different from each other. To solve the problem of redundancy, PHP provides two keywords, include and require. Without using the include keyword, the code can be messy or redundant. It saves us from writing the code of the file again and again everywhere we want to use its code. Include the keyword in PHP allows using an external file having PHP script, in the current file. In the next section, we will learn about two simple, but very easy, and important concepts of PHP. Now, pass this function as a callback function.Īs you are now familiar with the JSON format, json_encode, json_decode, and callback functions in PHP. Just like a normal function, use argument variables in your function.

How to use user-defined function as callback function? In the following example, you will learn how to pass an anonymous function as a callback function in PHP. PHP 7 and 8 can now pass an anonymous function as a callback function. Look at the following example of a simple callback function in PHP. In this case, just pass the name of the function as a string. You can define your own callback function and pass it to another function. Look at the following example in which we iterate over the json_decode result.Ī function passed as an argument to another function is called a callback function. So, foreach loop can access both the keys and their values in json_decode. How to loop through the json_decode array?Īs we know, json_decode returns an associative array. We will show you examples to access values from each of these outputs.Įxample 1 – json_decode returns object Peter Įxample 2 – json_decode returns an associative array
How to access the json_decode return values?Īs we see above that json_decode returns an object by default and an associative array when the second parameter becomes true. The following example makes use of the second parameter of json_decode. If it is set to true, it returns an associative array. If it is set to false, it returns an object. The second parameter of json_decode is a boolean. Json_decode is used to convert or decode back the JSON object into an associative array (key-value pairs) or a PHP value. Json_encode is used to encode or convert a value into JSON formate. There are some built-in JSON functions in PHP.
JSON is used all over the world by almost all languages, therefore it plays an important role in making cross-platform requests and getting responses.Įvery language is capable of reading JSON so, most of the API calls are used JSON input data and response output. It is a structure to represent the data in a more readable form. JSON stands for Javascript Object Notation. Also, we will look at the Callback functions in PHP.
In this article, you will learn about JSON format and its available PHP functions.
