/**
 *
 * Safe Search and Replace on Database with Serialized Data v3.0.0
 *
 * This script is to solve the problem of doing database search and replace when
 * some data is stored within PHP serialized arrays or objects.
 *
 * For more information, see
 * http://interconnectit.com/124/search-and-replace-for-wordpress-databases/
 *
 * To contribute go to
 * http://github.com/interconnectit/search-replace-db
 *
 * To use, load the script on your server and point your web browser to it.
 * In some situations, consider using the command line interface version.
 *
 * BIG WARNING!  Take a backup first, and carefully test the results of this
 * code. If you don't, and you vape your data then you only have yourself to
 * blame. Seriously.  And if your English is bad and you don't fully
 * understand the instructions then STOP. Right there. Yes. Before you do any
 * damage.
 *
 * USE OF THIS SCRIPT IS ENTIRELY AT YOUR OWN RISK. I/We accept no liability
 * from its use.

 *
 *
 * Version 3.0.0:
 * 		* Major overhaul
 * 		* Multibyte string replacements
 * 		* UI completely redesigned
 * 		* Removed all links from script until 'delete' has been clicked to avoid
 * 		  security risk from our access logs
 * 		* Search replace functionality moved to it's own separate class
 * 		* Replacements done table by table to avoid timeouts
 * 		* Convert tables to InnoDB
 * 		* Convert tables to utf8_unicode_ci
 * 		* Use PDO if available
 * 		* Preview/view changes
 * 		* Optionally use preg_replace()
 * 		* Scripts bootstraps WordPress/Drupal to avoid issues with unknown
 * 		  serialised objects/classes
 * 		* Added marketing stuff to deleted screen (sorry but we're running a
 * 		  business!)
 *
 * Version 2.2.0:
 * 		* Added remove script patch from David Anderson (wordshell.net)
 * 		* Added ability to replace strings with nothing
 *		* Copy changes
 * 		* Added code to recursive_unserialize_replace to deal with objects not
 * 		just arrays. This was submitted by Tina Matter.
 * 		ToDo: Test object handling. Not sure how it will cope with object in the
 * 		db created with classes that don't exist in anything but the base PHP.
 *
 * Version 2.1.0:
 *              - Changed to version 2.1.0
 *		* Following change by Sergei Biryukov - merged in and tested by Dave Coveney
 *              - Added Charset Support (tested with UTF-8, not tested on other charsets)
 *		* Following changes implemented by James Whitehead with thanks to all the commenters and feedback given!
 * 		- Removed PHP warnings if you go to step 3+ without DB details.
 * 		- Added options to skip changing the guid column. If there are other
 * 		columns that need excluding you can add them to the $exclude_cols global
 * 		array. May choose to add another option to the table select page to let
 * 		you add to this array from the front end.
 * 		- Minor tweak to label styling.
 * 		- Added comments to each of the functions.
 * 		- Removed a dead param from icit_srdb_replacer
 * Version 2.0.0:
 * 		- returned to using unserialize function to check if string is
 * 		serialized or not
 * 		- marked is_serialized_string function as deprecated
 * 		- changed form order to improve usability and make use on multisites a
 * 		bit less scary
 * 		- changed to version 2, as really should have done when the UI was
 * 		introduced
 * 		- added a recursive array walker to deal with serialized strings being
 * 		stored in serialized strings. Yes, really.
 * 		- changes by James R Whitehead (kudos for recursive walker) and David
 * 		Coveney 2011-08-26
 *  Version 1.0.2:
 *  	- typos corrected, button text tweak - David Coveney / Robert O'Rourke
 *  Version 1.0.1
 *  	- styling and form added by James R Whitehead.
 *
 *  Credits:  moz667 at gmail dot com for his recursive_array_replace posted at
 *            uk.php.net which saved me a little time - a perfect sample for me
 *            and seems to work in all cases.

			<h2>Safe Search and Replace on Database with Serialized Data v3.0.0</h2>

			<p>This developer/sysadmin tool carries out search/replace functions on MySQL DBs and can handle serialised PHP Arrays and Objects.</p>

			<p><strong class="red">WARNINGS!</strong>
			Ensure data is backed up.
			We take no responsibility for any damage caused by this script or its misuse.
			DB Connection Settings are auto-filled when WordPress or Drupal is detected but can be confused by commented out settings so CHECK!
			There is NO UNDO!
			Be careful running this script on a production server.</p>

			<h3>Don't Forget to Remove Me!</h3>

			<p>Delete this utility from your
			server after use by clicking the 'delete me' button. It represents a major security threat to your database if
			maliciously used.</p>

			<p>If you have feedback or want to contribute to this script click the delete button to find out how.</p>

			<p><em>We don't put links on the search replace UI itself to avoid seeing URLs for the script in our access logs.</em></p>

			<h3>Again, use Of This Script Is Entirely At Your Own Risk</h3>

			<p>The easiest and safest way to use this script is to copy your site's files and DB to a new location.
			You then, if required, fix up your .htaccess and wp-config.php appropriately.  Once
			done, run this script, select your tables (in most cases all of them) and then
			enter the search replace strings.  You can press back in your browser to do
			this several times, as may be required in some cases.</p>
