JSON encode and decode in PHP
Hi friends, in this tutorial you will learn JSON encode and decode in PHP. Before getting started with JSON with respect to PHP, you must know what JSON means exactly. JSON is nothing but a javascript object notation with a specific syntax or format as shown below.
{'key':value,'key1':value1,'key2':value2,'key3':value3}
Why we use JSON:- However, if we receive data from any kind of third-party application or via URL with the help of API then we can not use those data in PHP or we can not insert those data in our MySQL database. So, in order to overcome this problem, JSON helps us to convert those data into an associative array or indexed array by encode and decode functions so that we can access those data in the form of array values one by one and store them in php variables.
