Data storing in to database enables us to keep the information safe and secure, but what if we wish to update it. Here we are with the proper solution i.e. Update data in database using PHP. In this blog post we will show you  how to update previously stored information in database using PHP.

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

“employee_id”, “employee_name”, “employee_email”, “employee_contact” and “employee_address”.

next we create a php page named “updatephp.php” where following steps will be performed:

  • Establish connection with server .
  • Selecting database.
  • Executing query.
  • Closing connection with server.

 Below is our complete code with download and live demo option

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)
)
