A web service allows for data transfer between platforms or languages. It uses PHP code to perform operations like inserting, deleting, fetching, and updating data in a database. The web service code connects to the database using a connection file that contains login credentials. It then decodes request parameters, fires SQL queries to perform the requested operation, and encodes the response. URLs are used to check the operation by passing parameters to specify things like the table row ID, field names, and new values.

2. Web Service
• Web service used for data transferring between
two language or two platform
• In other words web service is known as script
code
• Firstly we create database
• For performing operation on database we use
php code
• By using query we can operate database

3. Web Service
• Query fired inside php(webservice) code so we
can say that this web service code is
responsible for :
1. Insert data into database
2. Delete data from database
3. Fetch data from database
4. Update data into database

4. Web Service
• For establish connection between database
and php code we use connection file
• Code of connection file is also written in php
Code of connection file:

5. Connection file
Here
Localhost:127.0.0.1
Root: user_name of vertrigo(local server)
Vertrigo: password of vertrigo
• Connection file save with extension of php
• This connection file include inside the
webservice(php) code in which query fired

6. STEP FOR CREATE WEB SERVICE CODE
1. Call connection file for establish connection
2. Create array because multiple value
insert/delete/fetch/update into database
3. Check value(isset variable used for checking
value)
4. Initialize Get method
5. Decode field
6. Fire query
7. Check data operate(according to query)or not
8. Lastly encode

7. DATABASE
• Firstly create database than create table

8. CODE FOR INSET DATA INTO DATABASE

9. CODE FOR delete DATA from DATABASE

10. CODE FOR update DATA INTO DATABASE

11. CODE FOR fetch DATA from DATABASE

12. URL FOR CHECK OPERATION
• URL for insertion of data:
(127.0.0.1/web/insert.php?u_name=santosh&
u_fname=mr.surender)
Here:
web- folder name
Insert.php-file name
• Entry of first field with “?” and entry of all
other with “&”

13. URL FOR CHECK OPERATION
• URL for deletion of data:
(127.0.0.1/web/delete.php?id=2)
Here:
Delete u_id=2 raw from table
• URL for updation of data:
(127.0.0.1/web/update.php?id=2&u_name=san
tu&u_fname=mr.surender)

14. URL FOR CHECK OPERATION
• URL for fetch data from database
(127.0.0.1/web/fetch.php)
