PHP CRUD operations with MySQL<\/a> database is the best way to create (insert), read (select), update, and delete records in the web application. The JSON file can be used to integrate CRUD functionality in PHP instead of a database like MySQL. In this tutorial, we will show you how to create a simple CRUD application to list, view, add, edit, and delete records with JSON file using PHP.<\/p>\nWe will implement the following functionality to build an example PHP CRUD script with JSON<\/b>.<\/p>\n\n- Fetch members’ data from the JSON file and list it on the web page.<\/li>\n
- Add and insert member data in the JSON file using PHP.<\/li>\n
- Edit and update member data in JSON file.<\/li>\n
- Delete member data from the JSON file.<\/li>\n<\/ul>\n
Before getting started to create a CRUD application with JSON file and PHP<\/b>, take a look at the file structure.<\/p>\nphp_crud_with_json\/<\/span>\r\n\u251c\u2500\u2500 index.php\r\n\u251c\u2500\u2500 addEdit.php\r\n\u251c\u2500\u2500 userAction.php\r\n\u251c\u2500\u2500 Json.class.php\r\n\u251c\u2500\u2500 json_files\/<\/span>\r\n\u251c\u2500\u2500 bootstrap\/<\/span>\r\n\u2502 \u2514\u2500\u2500 bootstrap.min.css\r\n\u251c\u2500\u2500 css\/<\/span>\r\n\u2502 \u2514\u2500\u2500 style.css\r\n\u2514\u2500\u2500 images\/<\/span>\r\n<\/pre>\nCreate JSON File<\/h2>\n
Since the JSON file will be used to store data without using any database, a JSON file is required. In the \u201cjson_files\/\u201d directory, the JSON files will be created dynamically to store the member\u2019s information.<\/p>\n
\n- Name (
name<\/code>)<\/li>\n- Email (
email<\/code>)<\/li>\n- Phone (
phone<\/code>)<\/li>\n- Country (
country<\/code>)<\/li>\n<\/ul>\nThe stored data format in the JSON file will look like below.<\/p>\n
[\r\n {\r\n \"name\"<\/span>: \"John Doe\"<\/span>,\r\n \"email\"<\/span>: \"john@codex.com\"<\/span>,\r\n \"phone\"<\/span>: \"123-456-7890\"<\/span>,\r\n \"country\"<\/span>: \"USA\"<\/span>,\r\n \"id\"<\/span>: 1646116158<\/span>\r\n }\r\n]<\/pre>\nJSON Handler Class (Json.class.php)<\/h2>\n
The Json class is a custom PHP library that handles all the CRUD-related operations (fetch, insert, update, and delete) with JSON file. Specify the directory where the JSON file will be stored and the name of the JSON file ($jsonFile).<\/p>\n
\n- getRows()<\/b> – Fetch records from the JSON file using file_get_contents() function in PHP.\n
\n- The PHP usort() function is used to sort array data in descending order.<\/li>\n<\/ul>\n<\/li>\n
- getSingle()<\/b> – Get single record from the JSON data by ID using array_filter() function in PHP.<\/li>\n
- insert()<\/b> – Store data into the JSON file using file_put_contents() function in PHP.<\/li>\n
- update()<\/b> – Update existing data by ID in the JSON file.<\/li>\n
- delete()<\/b> – Remove a record from the JSON file by ID.<\/li>\n<\/ul>\n
