Question

I have a random string set in each array index.And i want to give them a nice pattern.Better if i explain my problem in an example :
Let my array is like this :

                 Array
                      {
                         [0]=>A Man of with Dignity
                         [1]=>A supplier *Coming*
                         [2]=>Break the "Glasses"
                         [3]=>Broken 'law'
                      }

I am expecting the out up as :

                     Array
                        {
                              [0]=>a-man-with-dignity
                              [1]=>a-supplier-coming
                              [2]=>break-the-glasses
                              [3]=>broken-law
                        }

means i want to add “-” in the middle of each word and want them in lower case.And if there is any other special character that must be removed too.

Thanks for reading

Answer 1

use strtolower() and preg_replace():

$array = array("A Man of with Dignity",
               "A supplier *Coming*",
               "Break the \"Glasses\"",
               "Broken 'law'"
              );

foreach ($array as &$item) {
        $item = preg_replace('/\W/', '-', strtolower($item));
        $item = preg_replace('/-+$|^-+/', '', $item);
        $item = preg_replace('/-+/', '-', $item);
}

print_r($array);

Output:

Array
(
    [0] => a-man-of-with-dignity
    [1] => a-supplier-coming
    [2] => break-the-glasses
    [3] => broken-law
)
