Total 5 TYPES of tables we can create
1. MYISAM
2. Heap
3. MERGE
4. INNO DB
5. ISAM
MyISAM is the default storage engine as of MYSQL 3.23. When you fire the above
create query MySQL will create a MyISAM table.

Once the Web server received the uploaded file, it will call the PHP script SPECIFIED in the form action attribute to process them. This receiving PHP script can get the uploaded file information through the predefined array called $_FILES. Uploaded file information is organized in $_FILES as a two-dimensional array as:

• $_FILES[$fieldName]['name'] - The ORIGINAL file name on the BROWSER system.
•  $_FILES[$fieldName]['type'] - The file type determined by the browser.
•  $_FILES[$fieldName]['size'] - The Number of bytes of the file content.
•  $_FILES[$fieldName]['tmp_name'] - The temporary filename of the file in which
  the uploaded file was stored on the server.
•  $_FILES[$fieldName]['error'] - The error CODE associated with this file upload.
  The $fieldName is the name used in the .

urlencode() returns the URL encoded version of the given string. URL coding converts special characters into % signs FOLLOWED by two hex DIGITS. For example: urlencode("10.00%") will return "10%2E00%25". URL encoded strings are safe to be USED as part of URLs.
urldecode() returns the URL decoded version of the given string.

require_once() and include_once() are both the functions to INCLUDE and evaluate the specified FILE only once. If the specified file is INCLUDED previous to the present call occurrence, it will not be done again.

But require() and include() will do it as MANY TIMES they are asked to do.

A persistent cookie is a cookie which is stored in a cookie file permanently on the browser's computer. By default, cookies are created as temporary cookies which stored only in the browser's memory. When the browser is closed, temporary cookies will be ERASED. You should decide when to use temporary cookies and when to use persistent cookies BASED on their differences:

· Temporary cookies can not be used for tracking long-term information.
· Persistent cookies can be used for tracking long-term information.
· Temporary cookies are SAFER because no programs other than the browser can access them.
· Persistent cookies are less secure because users can OPEN cookie files see the cookie VALUES.

The syntex for REPAIRING a MYSQL table is:

REPAIR TABLE tablename
REPAIR TABLE tablename QUICK
REPAIR TABLE tablename EXTENDED

This command will repair the table specified.
If QUICK is GIVEN, MySQL will do a repair of only the index tree.
If EXTENDED is given, it will create index row by row.
