Introduction
Hi guys. In this article we are going to understand the MySQL
database with PHP. A database is an organized collection of data for one or more
purposes, usually in digital form. A database holds one or multiple tables. Creation of database
Here in this section we will use the Create database statement to create the
database.
Syntax
CREATE DATABASE database_name
Now we will focus on the creation of a database
with PHP script. When using PHP to execute the statement above we must use the mysql_query()
function. This function is used to send a query or command to a MySQL
connection.
PHP script for creating database:
<html>
<body bgcolor="Lightgreen">
<center>
<h3>
Creating a database <h3>
<hr>
<?php
$con
= mysql_connect("localhost","root","");
$db="Mike";
if (!$con)
{
die('Could
not connect: ' .
mysql_error());
}
if (mysql_query("CREATE
DATABASE $db",$con))
{
echo
"Database
created : $db";
}
else
{
echo
"Error
creating database: " .
mysql_error();
}
mysql_close($con);
?>
</center>
</body>
</html>
Save
it as abcd.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/abcd.php
Once your database has been created, and if
you hit the same URL again, the output will look as in the following:
Creation of Table
Here in this section we will create the table in a particular database. MySQL
provides a variety of table types with varying levels of
functionality. The CREATE TABLE statement is used to create a table in MySQL.
Syntax
CREATE TABLE table_name
(
column_name1 data_type,
column_name2 data_type
)
Now we will focus on the creation of a table with a particular database with PHP
script. The CREATE TABLE statement to the mysql_query() function to execute the
command.
PHP script for creating database table:
<html>
<body bgcolor="Lightgreen">

Creating a database table <h3>
<hr>
<?php
$con
= mysql_connect("localhost","root","");
if (!$con)
{
die('Could

mysql_error());
}
//
Create database
if (mysql_query("CREATE
DATABASE dwij",$con))
{
echo
"dwij
Database created";
}
else
{
echo
"Error

mysql_error();
}
//
Create table
mysql_select_db("dwij",
$con);
$sql = "CREATE
TABLE PBL
(
FirstName varchar(15),
LastName varchar(15),
Age int
)";
//
Execute query
mysql_query($sql,$con);
echo "PBL table
created";
mysql_close($con);
?>
</center>
</body>
</html>
Save it as abcd.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/abcd.php
Conclusion : With the
help of the script shwn above we can execute each SQL statement of MySQL with a PHP script.
Thanks !
