Just a simple trim function with full code. Trim functions are used in many areas and this will be a handy tutorial to give you a bigger picture of what trim actually does. Trim usually Strip whitespace (or other characters) from the beginning and end of a string
Below is a simple html form that post some data to a php script[trim.php]
<head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title>Simple Trim Function Using PHP</title> </head> <body> <form action="trim.php" method="post"> Type any thing <input type="text" name="word"/> <input name="submit" type="submit" value="Length"/> </form> </body> </html>
For example i have inserted a word “Welcome To PHP” inside the text field above.

<?php $word=$_POST['word']; echo trim($word,"Welcome"); ?>
Find out yourself what the output will be once you run the script. Have a good one. 🙂
