How to strip excess whitespace from a string with preg_replace()

PHP provides many pre-defined methods to deal with strings. One of the strong way to deal with strings is to use regular expressions aka ‘regex‘.

Let’s use regular expression with preg_replace() method to strip excess whitespace from a string.

  //the string from where you want to strip excess spaces
  $string = 'This       is the       sting       text';
  //apply regular expression with preg_replace to remove all spaces
  $string = preg_replace('/\s\s+/', ' ', $string);
  //this will print 'This is the string text'
  echo $str;

If you know any other alternative, please post in comments. I’ll add it in this article.
