Export picture from mysql database to file

As our data getting mobile and copying picture is annoying for me I decide to save the picture in the database (mysql).

Another challenge came when other division need the data exported in a directory with same dimension (135 x 180 pixel).

Structure for table ‘student_pic’  :

CREATE TABLE `student_pic` (
  `image_id` int(10) unsigned NOT NULL auto_increment,
  `username` varchar(50) NOT NULL default ”,
  `image_type` varchar(50) NOT NULL default ”,
  `image` longblob NOT NULL,
  `image_size` bigint(20) NOT NULL default ‘0’,
  `image_name` varchar(255) NOT NULL default ”,
  `image_date` datetime NOT NULL default ‘0000-00-00 00:00:00’,
  UNIQUE KEY `image_id` (`image_id`)

Yes, I use mysql 5 ( 5.0.45)

Multiple domains login in roundcube webmail

Roundcube is very good solution for webmail. I use squirrelmail for almost 4 years and I like it too.

In production server I install squirrelmail and roundcube as well for give other user different experience :-)

using mail and mail2 as prefix and multiple domains need special attention in roundcube.

After search in their forum I like this snippet :

 function getDomain() {




    if ($arr[0]==$prefix) { unset($arr[0]); $host=implode(‘.’,$arr); }

    else { $host=”; }

    return $host;


plus this line :

$rcmail_config[‘username_domain’] = getDomain();

 put that in config/main.inc.php

for my case where I use mail and mail2 just edit the line :

if ($arr[0]==$prefix) { unset($arr[0]); $host=implode(‘.’,$arr); }


if ($arr[0]==$prefix or $arr[0]==’mail2′) {

unset($arr[0]); $host=implode(‘.’,$arr);


 Working  well for me :-)
