mysql-logtable-php

mysql-logtable-php is a set of PHP scripts which leverage MySQL INFORMATION_SCHEMA to create log tables and insert / update triggers.

Configuration

Get started by entering your database credentials in configure.php.

7   $username = '{username}';
8   $password = '{password}';
9   $database = '{database}';

Demo

Schema for demo_mysql_logtable_php

CREATE DATABASE demo_mysql_logtable_php CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
USE demo_mysql_logtable_php;

DROP TABLE IF EXISTS client;
CREATE TABLE client (
    client_id INT NOT NULL AUTO_INCREMENT,
    client_email VARCHAR ( 50 ) NOT NULL,
    client_passcode_hash BINARY ( 128 ),
    client_salt CHAR ( 36 ),
    last_modified_datetime TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
    PRIMARY KEY ( client_id ),
    CONSTRAINT unique_client_email UNIQUE ( client_email )
);
