PHP Interview Question:

How To Remove Leading and Trailing Spaces from User Input Values in PHP?

Submitted by: Administrator

If you are taking input values from users with a Web form, users may enter extra spaces at the beginning and/or the end of the input values. You should always use the trim() function to remove those extra spaces as shown in this PHP script:

<?php
$name = $_REQUEST("name");
$name = trim($name);
# $name is ready to be used...
?>
