Retrieving Data from MYSQL Database using PHP

Using these easy steps you can easily retrieve the data from MYSQL database. In this example I am assuming that you have already created MYSQL database and already contains some tabular data.

Create database named mydb

CREATEDATABASE `mydb`;

Create Table student on mydb Database:

Table info is created with three fields: id, name and Email Address. Id will be automatically incremented after every insert operation.

CREATE TABLE `mydb`.`student` (

`id` INT NOT NULL AUTO_INCREMENT,
`name`VARCHAR(100)NOTNULL,
`contact_no`int(20)NOTNULL,
PRIMARYKEY(`id`)

) ENGINE = MYISAM

Insert some raw data for Accessing

INSERT INTO `mydb`.`student` (`id`, `name`, `contact_no`) VALUES (NULL, 'Dashmesh', '123456');

Create Database Connection (connection.php)

<?php

$host="localhost";

$username="your_db_username";

$password="your_db_password";

$db_name="mydb";

$con=mysql_connect("$host","$username","$password") or die("could not connect");

$db=mysql_select_db("$db_name")or die("cannot select DB");

?>

Now create a page that will retrieve data from Database(index.php)

<?php

include("connection.php");

$sql="SELECT * FROM student order by id";

$result=mysql_query($sql);

?>

<table width="525" border="1" align="center" cellpadding="3" cellspacing="1" bordercolor="#9933CC">

  <tr>

    <td colspan="10"><div align="center"><strong><font color="#000080" size="5"><b>Students

        List </b></font></strong></div></td>

  </tr>

  <tr align="center" valign="top">

    <td width="147"> <div align="center"><strong><font color="#000080" size="3.5">ID</font></strong></div></td>

    <td width="136"> <div align="center"><strong><font color="#000099">Name</font></strong></div></td>

    <td width="212"> <div align="center"><strong><font color="#000080" size="3.5">Contact

        No. </font></strong></div></td>

  </tr>

  <? while($rows=mysql_fetch_array($result)){

?>

  <tr align="center" valign="top">

    <td height="46"><? echo $rows['id']; ?> <div align="center"></div></td>

    <td><? echo $rows['name']; ?></td>

    <td><? echo $rows['contact_no']; ?></td>

  </tr>

  <?php

}

?>

Result so obtained will be as follows:

Students List
ID	Name	Contact No.
1	Dashmesh	123456
