Introduction

Hi guys. In this article we are going to understand the database select statement using PHP. The SELECT statement is used to select data from a database.

Select Data From a Database Table

In this section we going to work with the select statement to fetch data from the database.

Syntax

SELECT column_name(s) FROM table_name

PHP script for Fetching up data from table

<html>
<body bgcolor="pink">
 <center>
<h3> Select data from database table PBL ! <h3>
<hr>
<?php
$con = mysql_connect("localhost","root","");
 if (!$con)
{
 die('Could not connect: ' . mysql_error());
}
mysql_select_db("dwij", $con);
$result = mysql_query("SELECT * FROM PBL");
 while($row = mysql_fetch_array($result))
{
 echo $row['FirstName'] . " " . $row['LastName'];
 echo "<br />";
}
mysql_close($con);
?>
</center>
</body>
</html>

Save it as select.php.

Output

 To run the code, Open the XAMPP server and start the services like Apache and MySQL. Open the browser type:

http://localhost/yourfoldername/select.php

Elaboration of the preceding script:

  • The mysql_query() function stores the data returned in the $result variable.
  • The mysql_fetch_array() function to return the first row from the recordset as an array.
  • Each call to mysql_fetch_array() returns the next row in the recordset.
  • To print the value of each row, we use the PHP $row variable ($row['FirstName'] and $row['LastName']).

</tr>";
 while($row = mysql_fetch_array($result))
{
 echo "<tr>";
 echo "<td>" . $row['FirstName'] . "</td>";
 echo "<td>" . $row['LastName'] . "</td>";
