Before getting started to implement Authorize.Net payment gateway in PHP<\/b>, take a look at the files structure.<\/p>\nauthorize.net_integration_php\/<\/span>\r\n\u251c\u2500\u2500 config.php\r\n\u251c\u2500\u2500 dbConnect.php\r\n\u251c\u2500\u2500 index.php\r\n\u251c\u2500\u2500 payment.php\r\n\u251c\u2500\u2500 authorize_net_sdk_php\/<\/span>\r\n\u2514\u2500\u2500 css\/<\/span>\r\n \u2514\u2500\u2500 style.css\r\n<\/pre>\nCreate Database Table<\/h2>\n
