Full code
index.php

include_once('db.php');
if(isset($_POST['name']))
{
$name = $_POST['name'];
if(mysql_query("INSERT INTO apple VALUES('','$name')"))
echo "Successful Insertion!";
else
echo "Please try again";
}
$res = mysql_query("SELECT * FROM apple");
?>
<form action="." method="POST">
Name: <input type="text" name="name"/><br />
<input type="submit" value=" Enter "/>
</form>
<h1>List of companies ..</h1>
< ?php
while( $row = mysql_fetch_array($res) )
echo "$row[id]. $row[name] <br />";
?> |
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

I’m using this code for display all values inside database:
http://pastebin.com/dnPK47BQ
But the problem is that i want FIND a specific word..If i search Satish like word i want see in result page only fields containing Satish words not all database. How code can i use?
@elixir1349, Create a html form first, with a input box to put your search term.
Next in it’s action field, put the name of your php file.
Get the search term in your php file using POST or GET method(preferably GET method to this kind of applications). Assign the user entered search term to a php variable $search.
Now modify your MySQL query:
$sql = “SELECT * FROM demo WHERE Autore = ‘$search'”;
$res = mysql_query($sql);
Am assuming that the search term to be compared if present inside the field Autore.
Hope this helps..
