Php replace multiple spaces with single space

by

To replace multiple spaces with a single space in PHP, you can use the preg_replace() function with a regular expression pattern.
The regular expression pattern is /\s+/\, which matches one or more whitespace characters.
Here is an example: 

    
      $string = "Hello     World!";
      $newString = preg_replace('/\s+/', ' ', $string);
      
      echo $newString;

In this example, the variable $string contains the string "Hello World!" with multiple spaces between the words.
The preg_replace() function replaces all occurrences of one or more consecutive whitespace characters with a single space.
The resulting string, stored in the variable $newString, will be "Hello World!".
Finally, the echo statement outputs the modified string.
