You should use rtrim instead. It will remove extra white space at the end of a string and is faster than using preg_replace.

$str = "This is a string.    ";
echo rtrim($str);

Answer 7

for a string $string = " my name is Stark "; use ltrim($string) to trim whitespace from the beginning of the string, use rtrim($string) to trim whitespace from the end of the string, use trim($string) to remove whitespace from both ends. you can also add an extra parameter (a character mask) if you want to specifically remove another character also, apart from whitespace from the end or beginning of a string e.g trailing slashes(" onefunnyurl.com/")
