Validating url php Phone sex and webcam

The PHP filter extension has many of the functions needed for checking user input, and is designed to make data validation easier and quicker.The function to check if the variable $int is an integer.This tutorial gained your knowledge on validating emails, URLs, integers, booleans and more.Finally we created a class to make validating more convenient.So, in the next step we will be creating a class to validate inputs in a more convenient way.I assume that you have basic knowledge on Object Oriented Programming. Our class must prevent XSS attacks and validate inputs.If $int is an integer, the output of the code below will be: "Integer is valid".

In the following code we have added some new variables: $name Err, $email Err, $gender Err, and $website Err.

If you are sending sensitive data such as passwords, emails with HTTP request you must use POST. But, if the email is compulsory, we have to throw an error if it's empty.

If you are retrieving data from the server, you can use GET method. Here I have chosen POST method and the action script, is requested with any other method, it will show an error. Next, we have to check the user inputs to avoid processing errors. Assume that you have php code to assign POST variable to a local variable as following. The last subtopic of this tutorial will explain you to do that in an object oriented way. We save his username in the database without any validation.
