In php, replace the space in the string with comma ','.

This article describes how to replace spaces in strings with commas in php. I feel pretty good. you can refer to today's online article about replacing the space in the string with commas (,) in php and save it as a diary.
The code is as follows:

 /*
* Replace the space in the keyword ','
*/
Public function emptyreplace ($ str ){
$ Str = str_replace ('','', $ str); // replace the full-width space with a half-width space.
$ Str = str_replace ('','', $ str); // replace consecutive spaces with one
$ Noe = false; // whether a character other than a space is encountered
For ($ I = 0; $ I

 
  
If ($ noe & $ str [$ I] = '') $ str [$ I] = ','; // if the current space is preceded by a character other than a space

  
Elseif ($ str [$ I]! = '') $ Noe = true; // The current character is not a space. The $ noe variable is defined.

  
}

  
Return $ str;

  
}
