Question

I am trying to strip all special chars and add a dash between all the words.

Example:

Example text:
How to make something, something else, and other stuff.

Example string:

$string = "How to make something, something else, and other stuff.";

Example of how it should look:
How-to-make-something-something-else-and-other-stuff

I need a function that will strip all special chars but also add the dashes between every word “but also not adding dashes after the last word”. Anyone have any ideas of how I should do this? I assume this is fairly simple. probably a preg_replace with regex which would solve the special char problem but adding the dashes is where I get confused and am not sure what to do.

Answer 1

Assuming the string is in utf-8:

$string = 'Höw to máke sòmething, something else, and other stuff';
$string = preg_replace('/[^a-z0-9]+/i','-',
   iconv('UTF-8','ASCII//TRANSLIT',$string));
$string = trim($string,'-');
