In an effort to make searching entire databases for specific strings, numbers, and email addresses easier, I have made this script that will pull the list of tables and their respective columns from the database and then search each and every column for the search term, e.g.,
SELECT column_name
FROM table_name
WHERE column_name LIKE '%search_term%'
This tool can take a very long time to run. It is literally searching every column in every table with a wildcard search term.
You will need the php-yaml PECL extension (for parsing the YAML).
Put this directory somewhere accessible via a web browser.
Create a database.yml in the this directory with your desired searchable databases. See database.yml.example for what it should look like.
Navigate to the script, e.g., http://localhost/searchysearch/mysql-search.php, select your client, enter a search term, and hit Search.
Results will be grouped by table name, and then by column name. Each matching row will be numbered and your search term will be highlighted.
At the very bottom of the page, it will give you the total number of matched rows.
