Regular expression to ignore escaped quotes within quotes

Language: PHP

I have string:
$text = '[[["my tree \",and to and \"\" something \'\"else","moe derevo \" , a takzhe i\" \"nechto \" drugoe",""]],,"en",,[["en"]],2]';
I need only quoted part of it:  my tree \",and to and \"\" something \'\"else


$pattern = '/"([^"\\\\]*(?:\\\\.[^"\\\\]*)*)"/imsu'; // Use this regular expression
$match = '';
preg_match($pattern, $text, $match);

And you will see: my tree \",and to and \"\" something \'\"else

Magento database add table prefix

Store setup was without database table prefix.
Now I need to move magento database to existing db with tables from another application.

Magento version 1.6.0

Create script "add_db_prefix.php" in your store public catalog. Listing:

$database_host = "localhost"; // Here database server, ip or domain name
$database_user = "<your_db_user>";
$database_password = "<your_db_user_password>";
$magento_database = "<your_db_name>";
$table_prefix = "mage_"; // Table prefix wich you want!!!

$db = mysql_connect($database_host, $database_user, $database_password);
$result = mysql_query("SHOW TABLES") or die('Err');
while (($row = mysql_fetch_array($result)) != false) {
    $old_table = $row[0];
    if (preg_match('/'.$table_prefix.'/', $old_table)) {
        echo "Table $old_table already done<br/>\n";

    $new_table = $table_prefix.$old_table;
    echo "Renaming $old_table to $new_table<br/>\n";
    $query = "RENAME TABLE `$old_table`  TO `$new_table`";

Do not forget change db conection data in script!
Follow to the url: http://<your_store_domain_name>/add_db_prefix.php
Now all tables in db with new prefix.
And of course you need setup table prefix in your store config file.
Edit config: "app/etc/local.xml"
Find string: "<table_prefix><![CDATA[]]></table_prefix>"
Put there your new table prefix: "<table_prefix><![CDATA[mage_]]></table_prefix>"

Magento Admin Notification bugfix

Magento v.1.6
Every time when I am login to the admin panel see this message:"Reminder: Change Magento`s default phone numbers and callouts before site launch"
It's really damn annoying.

Copy the file app/code/core/Mage/AdminNotification/Model/Resource/Inbox.php
to app/code/local/Mage/AdminNotification/Model/Resource 
Create these folders if they does not exists.
And edit this php script.
Line 102. Find:
$select $adapter->select()
Replace it by:$select $adapter->select()
where('url=? OR url IS NULL'$item['url'])

Delete all your notifications.
