We have given a string and the task is to remove white space only from beginning of a string or end from a string str in PHP. In order to do this task, we have the following methods in PHP:
Method 1: Using ltrim() Method: The ltrim() method is used to strip whitespace only from the beginning of a string.
Syntax:
ltrim($string, $charlist)
Example :
PHP
<?php // PHP program to remove white space // from beginning of a string     $str = " Geeks for Geeks  ";     // Using ltrim() function // removes whitespaces from // beginning of a string $str = ltrim($str);   // Printing the result echo $str;   $len = strlen($str);   echo "\nLength of String: ";  echo $len; ?> |
Output
Geeks for Geeks Length of String: 20
Method 2: Using rtrim() Method: The rtrim() method is used to strip whitespace only from the end of a string.
Syntax:
rtrim($string, $charlist)
Example :
PHP
<?php // PHP program to remove white space // from the end of a string     $str = " Geeks for Geeks  ";     // Using rtrim() function to // remove whitespaces from // end of a string $str = rtrim($str);   // Printing the result echo $str;   $len = strlen($str); echo "\nLength of String : ";  echo $len; ?> |
Output
Geeks for Geeks Length of String : 19
