PHP SQL Connection
PHP SQL Connection is used to access and return the records from PHP and MySQL database and vice-versa.
Understand with Example
The Tutorial illustrate an example that helps you to understand how to establish the database connection between PHP and SQL. To understand the example we create a table 'Stu' with the required fieldnames and datatypes respectively. The table 'Stu' has a Primary Key id.
Create table Stu:
CREATE TABLE `stu` (
`id` int(11) NOT NULL ,
`name` varbinary(10) default NULL,
`class` int(11) default NULL,
PRIMARY KEY (`id`)
);
|
Insert data into Stu:
The insert into keyword adds the records or rows values to the table 'Stu'.
INSERT INTO `stu` VALUES (1,'Ajay',12); INSERT INTO `stu` VALUES (2,'Bhanu',12); INSERT INTO `stu` VALUES (3,'Komal',12); INSERT INTO `stu` VALUES (4,'Rakesh',12); INSERT INTO `stu` VALUES (5,'Santosh',12); INSERT INTO `stu` VALUES (6,'Tanuj',12); |
php_sql_fetch.php:
To access the data from table 'stu' firstly we need to include the host, user, password and database that connects the PHP server side to MySQL database in the PHP server side scripts. The variable Connection accept the host , user and password. Once the connection is built successfully, you are able to access and return the records from table 'stu'.
<html> <body> <?php $host = "localhost"; $user = "root"; $password = "root"; $database = "komal"; $connection = mysql_connect($host,$user,$password)
or die("Could not connect: ".mysql_error());
mysql_select_db($database,$connection)
or die("Error in selecting the database:".mysql_error());
$sql="Select * from stu"; $sql_result=mysql_query($sql,$connection)
or exit("Sql Error".mysql_error());
$sql_num=mysql_num_rows($sql_result); echo "<table width =\"20%\" bgcolor=\"#F5F5FF\">";
echo "<tr>";
echo "<td ><b>Id</b></td> <td><b>Name</b></td>
<td><b>Class</b></td>";
echo "</tr>";
while($sql_row=mysql_fetch_array($sql_result))
{
$id=$sql_row["id"];
$name=$sql_row["name"];
$class=$sql_row["class"];
echo "<tr><td>".$id."</td>"; echo "<td>".$name."</td>"; echo "<td>".$class."</td></tr>"; } echo "</table>" ?> </body> </html> |
Result
| Id | Name | Class |
| 1 | Ajay | 12 |
| 2 | Bhanu | 12 |
| 3 | Komal | 12 |
| 4 | Rakesh | 12 |
| 5 | Santosh | 12 |
| 6 | Tanuj | 12 |
