Better performance

Hi guys,

Have to remove all symbols, double spaces from text and add comma at the end of each word.

Did as follows below..but I think it can be done easiest way. Please advise.

 

$new = preg_replace('/[^a-zA-Z0-9\s]/', '', $tags_array['title']);
$new_string = preg_replace('/\s{2}/',' ', $new);
$string = preg_replace('/[^a-zA-Z0-9]/', ',', $new_string);

Do you need to remove triple spaces as well?  Because that code will only remove double spaces.  If the last line is specifically to replace spaces with commas you can use str_replace() instead.

No, I don't need to remove triple spaces. As I can understand if I have to remove any dublicated spaces I can use /\s+/ instead isn't?

Yes, replacing '\s+' with ' ' will convert any number of whitespace (which includes spaces and some other characters) with one space, which is usually good enough.  ' +' will match spaces only.
