As we know Database is a collection of tables that stores data in it.

To retrieve or fetch data from MySQL database it is simple to do it using MySQL ” Select ” query in PHP .

Here in this blog post we will be going to see how to fetch data and to display it in front end.

MySQL Select Query:

SELECT column_name(s)
FROM table_name

PHP:

$query = mysql_query("select * from tablename", $connection);

For this you must have a database in MySQL . Here, we have a database named “company” which consists of a table named “employee” with 5 fields in it.

Next we have created a PHP page named “updatephp.php” where following steps will be going to perform:

  • We first establish connection with server .
$connection = mysql_connect("localhost", "root", "");
  • Selects database.
$db = mysql_select_db("company", $connection);
  • Executes MySQL select query.
$query = mysql_query("select * from employee", $connection);
  • Display fetched data
<span>Name:</span> <?php echo $row1['employee_name']; ?>
<span>E-mail:</span> <?php echo $row1['employee_email']; ?>
<span>Contact No:</span> <?php echo $row1['employee_contact']; ?>
<span>Address:</span> <?php echo $row1['employee_address']; ?>
  • Closing connection with server.
mysql_close($connection);

MySQL Code Segment: Here is the MySQL code for creating database and table.


CREATE DATABASE company;
CREATE TABLE employee(
employee_id int(10) NOT NULL AUTO_INCREMENT,
employee_name varchar(255) NOT NULL,
employee_email varchar(255) NOT NULL,
employee_contact varchar(255) NOT NULL,
employee_address varchar(255) NOT NULL,
PRIMARY KEY (employee_id)
)
