Create Database Table<\/h2>\n
To store the user profile information from the Twitter account, a table needs to be created in the database. The following SQL creates a users<\/code> table with some basic fields in the MySQL database.<\/p>\nCREATE<\/span> TABLE<\/span> `users`<\/span> (\r\n `id`<\/span> int<\/span>(11<\/span>) NOT<\/span> NULL<\/span> AUTO_INCREMENT,\r\n `oauth_provider`<\/span> enum(''<\/span>,'facebook'<\/span>,'google'<\/span>,'twitter'<\/span>) COLLATE<\/span> utf8_unicode_ci NOT<\/span> NULL<\/span> DEFAULT<\/span> 'twitter'<\/span>,\r\n `oauth_uid`<\/span> varchar<\/span>(50<\/span>) COLLATE<\/span> utf8_unicode_ci NOT<\/span> NULL<\/span>,\r\n `first_name`<\/span> varchar<\/span>(25<\/span>) COLLATE<\/span> utf8_unicode_ci NOT<\/span> NULL<\/span>,\r\n `last_name`<\/span> varchar<\/span>(25<\/span>) COLLATE<\/span> utf8_unicode_ci NOT<\/span> NULL<\/span>,\r\n `email`<\/span> varchar<\/span>(25<\/span>) COLLATE<\/span> utf8_unicode_ci DEFAULT<\/span> NULL<\/span>,\r\n `gender`<\/span> varchar<\/span>(10<\/span>) COLLATE<\/span> utf8_unicode_ci DEFAULT<\/span> NULL<\/span>,\r\n `locale`<\/span> varchar<\/span>(10<\/span>) COLLATE<\/span> utf8_unicode_ci NOT<\/span> NULL<\/span>,\r\n `picture`<\/span> varchar<\/span>(200<\/span>) COLLATE<\/span> utf8_unicode_ci NOT<\/span> NULL<\/span>,\r\n `username`<\/span> varchar<\/span>(50<\/span>) COLLATE<\/span> utf8_unicode_ci NOT<\/span> NULL<\/span>,\r\n `link`<\/span> varchar<\/span>(100<\/span>) COLLATE<\/span> utf8_unicode_ci NOT<\/span> NULL<\/span>,\r\n `created`<\/span> datetime NOT<\/span> NULL<\/span>,\r\n `modified`<\/span> datetime NOT<\/span> NULL<\/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>\nTwitter OAuth Library for PHP<\/h2>\n
The twitter-oauth-php\/<\/b> directory contains the Twitter OAuth library that helps to integrate Twitter API with PHP. You don’t need to download the Twitter PHP OAuth library separately, all the required files are included in our Twitter Login PHP<\/b> source code.<\/p>\nUser Class (User.class.php)<\/h2>\n
The User class handles the database related operations (connect, insert, and update) using PHP and MySQL. It used to connect the database and insert\/update Twitter account data in the users table.<\/p>\n
\n- __construct()<\/b> \u2013 Connect to the MySQL database.<\/li>\n
- checkUser()<\/b> \u2013 Insert or update the user profile data based on the OAuth provider and ID. Returns the user’s account data as an array.<\/li>\n<\/ul>\n
