How to remove user input unnecessary white-space/character in php

In this how to remove user input unnecessary white space/character in php tutorial, I have showed that how to remove whitespace or character in php by using php building function trim(). Actually when you work with form & you want to get a specific data from your users, you need to use this trim function of php. This trim function will help you to remove unwanted character or white spaces from user input data.

Also you can specific remove white space or character by using php rtrim function or ltrim function. For removing right side white space or character just use php rtrim function but if you want to remove left side white-space or character just use ltrim function of php.

Here I have showed with live examples & hope you will enjoy this video.
