PHP or Hypertext Preprocessor is a feature-rich web programming language used for developing attractive websites with dynamic content that can interact with the database. While PHP supports the front-end user interface and functionality development for a website, the database provides a platform for storing, retrieving, and managing the data at the back end for the use of the website and its users. You can also create robust websites by having professional knowledge and you can get that professional knowledge by joining a PHP training institute.
MySQL is an open-source database platform capable of handling lots of data and database connections. With the knowledge of PHP and MySQL, one can develop the most powerful, fast, and scalable web applications which provide clean and simple usability to the users and one gets this knowledge by doing a PHP training course.
There are a few simple steps for creating a MySQL database using PHP.
First of all, install the latest version of MySQL on your PC or laptop.
Secondly, the admin privilege would be required in order to create a new database.
You can create a database using the mysql_query function.
Syntax of mysql_query function is
bool mysql_query( SQL, connection );
This would return true on success and false on failure. Usually, two parameters are passed within this boolean function. One is the query passed for creating the database and the other is the connection resource of the database. Being an optional parameter, if the connection is not specified here then the last opened connection by mysql_connect will be used.
Wondering what is mysql_connect? mysql_connect is a function through which a connection is established to the database. This function normally takes five parameters as input (all are optional) and returns a MySQL link identifier when the connection is established successfully or the “false” on failure to establish the connection.
The syntax of mysql_connect is as follows
connection mysql_connect(server, user, passwd, new_link, client_flag);
Here “server” represents the hostname that runs the database. By default, this value is “localhost:3306” while the “user” and “passwd” are usernames and passwords required for accessing the database. The new_link is a parameter specified in case the user wants to make a second call to the database. In this case, the new connection is not established and the identifier of the already created connection is returned. MYSQL_CLIENT_SSL, MYSQL_CLIENT_COMPRESS, MYSQL_CLIENT_IGNORE_SPACE, and MYSQL_CLIENT_INTERACTIVE are the constants you can specify for client flags in the last parameter of mysql_connect.
Example:
$db_host = ‘localhost:3036’;
$db_user = ‘training’;
$db_passwd = ‘training123’;
$connection = mysql_connect($db_host, $db_user, $db_passwd);
if(! $conn)
{
echo “Not Connected”;
}
echo “Connected successfully”;
$sql_query = ‘CREATE Database sample_db;
$retval = mysql_query( $sql_query, $connection );
if(! $retval)
{
echo “Could not create database”;
}
echo “Database sample_db created successfully”;
mysql_close($conn);//this closes the database connection after the process
?>
You have to now populate your database with appropriate data and for this, you have to create database tables as the database stores everything in structured tabular format.
To create a table, you will once again require the mysql_query function. This would be the same as database creation but the only difference would be in the query that is passed in the first parameter of mysql_query(). Here instead of the database creation query ‘CREATE Database database_name’, here table creating query ‘CREATE TABLE table_name (column_name column_type)’ will be passed.
Example:
$db_host = ‘localhost:3036’;
$db_user = ‘training’;
$db_passwd = ‘training123’;
$connection = mysql_connect($db_host, $db_user, $db_passwd);
if(! $conn)
{
echo “Not Connected”;
}
echo “Connected successfully”;
$ sql_query = ‘CREATE TABLE trainee ( ‘.
‘trainee_id INT NOT NULL AUTO_INCREMENT, ‘.
‘trainee _name VARCHAR(20) NOT NULL, ‘.
‘trainee _address VARCHAR(20) NOT NULL, ‘.
‘joined_course VARCHAR(30) NOT NULL, ‘.
‘join_date timestamp(14) NOT NULL, ‘.
‘primary key (trainee_id ))’;
mysql_select_db(‘ sample_db’);
$retval = mysql_query( $sql_query, $connection );
if(! $retval)
{
echo “Could not create database”;
}
echo “Database sample_db created successfully”;
mysql_close($conn);
?>
Hence, you have now got a database by the name “sample_db” having one row of data in it. Similarly, you can add much more data into your database by adding more tables to it like the one shown above and hence perform data managing functions on MySQL database using PHP.
