A PHP search replace tool for quickly modifying a string throughout a database. Useful for changing the base URL when migrating a WordPress site from development to production.
This script was made to aid the process of migrating PHP and MySQL based websites. It has additional features for WordPress and Drupal but works for most other similar CMSes.

If you would like Search Replace DB to detect your WordPress installation, you should install it within a new subfolder within your WordPress installation.
For example, if you have
/website.com/index.php /website.com/wp-config.php /website.com/wordpress/ /website.com/wordpress/index.php /website.com/wordpress/wp-settings.php etc.
You can copy Search Replace DB into the following location:
/website.com/wordpress/Search-Replace-DB/ /website.com/wordpress/Search-Replace-DB/index.php /website.com/wordpress/Search-Replace-DB/srdb.class.php /website.com/wordpress/Search-Replace-DB/srdb.cli.php etc.
To invoke the script, nagivate in your shell to the directory to where you installed Search Replace DB.

This happens occasionally and could be for a couple of reasons:
- When the script starts, it attempts to start your WordPress or Drupal installation to auto-detect your username and password settings. If this fails, you will see a message informing you that auto-detection failed. You will have to enter your details manually.
- Script was unable to set the timeout so PHP closed the connection before the table could be processed, this can happen on some server configurations.
- When using php-fpm (as you have with VVV) make sure that the socket is owned by the server user
chown www-data:www-data /var/run/php5-fpm.sock.
