PHP: remove excess space from string using regex

Question

How to remove extra spaces at the end of a line using regex (preg_replace)?

$string = "some random text with extra spaces at the end "; 

Answer 1

There is no need for a regular expression, and you can use rtrim to make it cleaner and faster:

 $str = rtrim($str); 

But if you want to use a regex-based solution, you can use:

 $str = preg_replace('/\s*$/','',$str); 

Regular expression used /\s*$/

• \s for any char space that includes space.
• * - quantifier for zero or more
• $ is the ultimate anchor

We basically replace the trailing space characters with nothing ( '' ), effectively removing them.

Answer 2

Here you do not need a regular expression, you can use the rtrim () function.

 $string = "some random text with extra spaces at the end "; $string = rtrim($string);
