  • 9 Jan, 2012

    There are 4 PHP functions you can use remove white space characters from the beginning and/or the end of a string:► trim() - Remove white space characters from the beginning and the end of a string.► ltrim() - Remove white space characters from the beginning of a string.► rtrim() - Remove white space characters from the end of a string.► chop() - Same as rtrim().White space characters are defined as:► " " (ASCII 32 (0x20)), an ordinary space.► " " (ASCII 9 (0x09)), a tab.► "" (ASCII 10 (0x0A)), a new line (line feed).► "" (ASCII 13 (0x0D)), a carriage return.► "" (ASCII 0 (0x00)), the NULL-byte.► "x0B" (ASCII 11 (0x0B)), a vertical tab.Here is a PHP script example of trimming strings:<?php$text = " Hello world! ";$leftTrimmed = ltrim($text);$rightTrimmed = rtrim($text);$bothTrimmed = trim($text);print("leftTrimmed = ($leftTrimmed)");print("rightTrimmed = ($rightTrimmed)");print("bothTrimmed = ($bothTrimmed)");?> This script will print:leftTrimmed = (Hello world! )rightTrimmed = ( Hello world!)bothTrimmed = (Hello world!)
