<h1>List of companies ..</h1>
< ?php
while( $row = mysql_fetch_array($res) )

while loop executes until there is data inside the table, once there is no more data to fetch, loop terminates.

MySQL Query

1
mysql> SELECT * FROM apple;

This mysql statement fetches data from all the fields of the table.
We could specify fields and get only list of those values.

Ex:

1
mysql> SELECT id FROM apple;

Using this we can get list of id’s only.

After fetching data from table apple

List of companies ..

1. Google
2. Apple
3. Microsoft
4. Oracle
5. Technotip
