Get data from MySQL in PHP

To get data from MySQl is a base for PHP programming.
First we create a table in XAMPP: (go to http://localhost/phpmyadmin/
or http://localhost/xampp if you installed XAMPP)
   username VARCHAR(20) NOT  NULL,
   income_type CHAR(1) NOT NULL,
    income DECIMAL(18,2)NOT NULL

Then insert some data:
INSERT INTO income(username,income_type,income) VALUES
 ('j1','A','2000.0' ),
 ('j2','B','2050.5' ),
 ('j3','A', '300.0'),
 ('j4','B', '400.0');

Now we fetch  this 2d array data using PHP:
//Connect to MySQL server
   $conn = @mysql_connect("localhost","root","") || die("MySQL connection error");
//Connect to database test
  @mysql_select_db("test") || die("test database not exist!"); 
   $income_data = Array();

 $sql = 'SELECT * FROM income';
  $result = mysql_query($sql);
   while($row = mysql_fetch_assoc($result)){
      // Assign  MySQL result to a multi-dimensional array
       $income_data[] = $row;
//Extract data from the multi-dimensional  array
echo '<h2>';
echo 'username, income_type, income <br />';
foreach($income_data as $my_data){
       foreach($my_data as $key=>$data) echo  $data.',   ';
        echo '<br />';
echo '</h2>';

Display all folder size in WIndows 7.

It is easy to the size of only one folder in Windows 7. Just right click the folder to see properties or mouse hover over the folder. But I want to see all the folders size at the same time.  There is a freeware for folder size can be downloaded from  the following link:

PHP/MySQL store time and compare time

1)Using MySQl datetime to create timestamp in year-month-day hour-minute-second
CREATE TABLE  `cnsh_lms`.`cesei_member_extra` (
  `member_id` mediumint(8) unsigned NOT NULL,
  `dept_type` tinyint(4) NOT NULL default '0',
  `edu_type` tinyint(4) NOT NULL default '0',
  `modify_date` datetime default '0000-00-00 00:00:00',
  PRIMARY KEY  (`member_id`)

2)  Using PHP function date('Y-m-d H:i:s') to create time compatible with MYSQL datetime
 $modify_date = date('Y-m-d H:i:s');   
3) Create a form to select month, day and year.
                      <select name="s_m" id="s_m">
                           for($time = 1; $time <= 12; $time++){
                              echo('<option value="'.$time.'"');
                                  if($_GET['s_m'] == $time)
                                 echo(' selected="selected"');
                              if(date("n") == $time){
                                  if(!isset($_GET['s_d'])) echo(' selected="selected"');
                     </select> -
                     <select name="s_d" id="s_d">
                           for($time = 1; $time <= 31; $time++){
                              echo('<option value="'.$time.'"');
                              if($_GET['s_d'] == $time)
                                 echo(' selected="selected"');
                              if(date("j") == $time){
                                 if(!isset($_GET['s_d'])) echo(' selected="selected"');
                              echo('>'.sprintf("%02d", $time).'</option>');
                     </select> -
                     <select name="s_y" id="s_y">
                           for($time = 2005; $time <= 2025; $time++){
                              echo('<option value="'.$time.'"');
                             if($_GET['s_y'] == $time)
                                 echo(' selected="selected"');
                              if(date("Y") == $time){
                                  if(!isset($_GET['s_y'])) echo(' selected="selected"');

4)  using PHP function mktime to return unix time
$search_date  = mktime(0,0,0,intval($_POST['s_m']),intval($_POST['s_d']),intval($_POST['s_y']));
5) Using MySQl UNIX_TIMESTAMP to transfer datetime to UNIX time to compare.
$sql="SELECT * FROM cesei_member_extra WHERE UNIX_TIMESTAMP(modify_date)  >= ".$search_edate;
