PHP CRUD operations<\/a> can help you to create and manage dynamic HTML pages with MySQL. In this tutorial, we will show you how to generate web pages and manage HTML content dynamically with database using PHP and MySQL.<\/p>\nIn this example script, the following functionality will be implemented to build dynamic HTML page management system with PHP<\/b> and MySQL.<\/p>\n\n- Fetch page data from the database and list them on the web page.<\/li>\n
- Create an HTML page with dynamic content using PHP.<\/li>\n
- Add and insert page data in the database using PHP and MySQL.<\/li>\n
- Create dynamic URL of the webpage and allow access to the dynamic web page.<\/li>\n
- Edit and update page content with PHP.<\/li>\n
- Delete page data from the database and HTML files from the server.<\/li>\n<\/ul>\n
Before getting started to create a CRUD application with dynamic HTML page management<\/b>, take a look at the file structure.<\/p>\npages_management_with_php\/<\/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 PageDb.class.php\r\n\u251c\u2500\u2500 config.php\r\n\u251c\u2500\u2500 common\/<\/span>\r\n\u2502 \u2514\u2500\u2500 cms.html\r\n\u251c\u2500\u2500 pages\/<\/span>\r\n\u2514\u2500\u2500 assets\/<\/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 \u251c\u2500\u2500 js\/<\/span>\r\n \u2502 \u251c\u2500\u2500 tinymce\/<\/span>\r\n \u2502 \u2514\u2500\u2500 jquery.min.js\r\n \u2514\u2500\u2500 images\/<\/span>\r\n<\/pre>\nCreate Database Table<\/h2>\n
To store page information a table is required in the database. The following SQL creates a pages<\/code> table with some required fields in the MySQL database.<\/p>\nCREATE<\/span> TABLE<\/span> `pages`<\/span> (\r\n `id`<\/span> int<\/span>(11<\/span>) NOT<\/span> NULL<\/span> AUTO_INCREMENT,\r\n `page_uri`<\/span> varchar<\/span>(255<\/span>) COLLATE<\/span> utf8_unicode_ci DEFAULT<\/span> NULL<\/span>,\r\n `title`<\/span> varchar<\/span>(255<\/span>) COLLATE<\/span> utf8_unicode_ci NOT<\/span> NULL<\/span>,\r\n `content`<\/span> text<\/span> COLLATE<\/span> utf8_unicode_ci DEFAULT<\/span> NULL<\/span>,\r\n `created`<\/span> datetime NOT<\/span> NULL<\/span> DEFAULT<\/span> current_timestamp<\/span>(),\r\n `modified`<\/span> datetime NOT<\/span> NULL<\/span> DEFAULT<\/span> current_timestamp<\/span>(),\r\n `status`<\/span> tinyint(1<\/span>) NOT<\/span> NULL<\/span> DEFAULT<\/span> 1<\/span> COMMENT<\/span> '1=Active | 0=Inactive'<\/span>,\r\n PRIMARY KEY<\/span> (`id`<\/span>)\r\n) ENGINE<\/span>=InnoDB<\/span> DEFAULT<\/span> CHARSET<\/span>=utf8 COLLATE<\/span>=utf8_unicode_ci;<\/pre>\nConfiguration File (config.php)<\/h2>\n
In the config.php<\/code> file, common settings and database configuration variables are defined.<\/p>\n\n$pageDir<\/code> – Specify the folder path where the page files will be stored.<\/li>\n$pageExtention<\/code> – Specify the extension of the page file (.html\/.php).<\/li>\n$list_excerpt_length<\/code> – Character limit of the content shown in the page list.<\/li>\nDB_HOST<\/code> – Database host.<\/li>\nDB_USERNAME<\/code> – Database username.<\/li>\nDB_PASSWORD<\/code> – Database password.<\/li>\nDB_NAME<\/code> – Database name.<\/li>\n<\/ul>\n<?php

The PageDb class is a custom PHP library that handles all the CRUD-related operations (fetch, insert, update, and delete) with MySQL.<\/p>\n
\ngetRows()<\/code> – Fetch records from the database using PHP and MySQL.<\/li>\ninsert()<\/code> – Insert data into the database.<\/li>\nupdate()<\/code> – Update existing data in the database based on specified conditions.<\/li>\ndelete()<\/code> – Remove a record from the database by ID.<\/li>\nisPageExists()<\/code> – Check if a record is existing with the same page title in the database.<\/li>\ngeneratePageUri()<\/code> – Generate page URL slug from string.<\/li>\n<\/ul>\n<?php
