Question

I have a textarea where I can type in multiple domain names to check availability.
In my script below I replace space with “-“. But I also want a version of the domain name without “-”.

Say for example that I type in:

a good word

a nother god word

Then I want the script to return both:

a-good-word

a-nother-god-word

And also:

agoodword

anothergodword

$domaininput = (isset($_POST['domainname'])) ? $_POST['domainname'] : '';
$change_space = str_replace(" ","-",$domaininput);
$change_new_line = str_replace("\n",",",$change_space);
$manydomains = explode("," , $change_new_line);
foreach ($manydomains as $domain){
//some code
}

How can that be done in PHP?

Answer 1

$manydomains = ... // as above...

// Get alternatives by removing dashes:
$alternatives = explode(",", str_replace("-", "", $change_new_line));

// If a domain name did not contain a dash, there will be duplicates in
// $manydomains and $alternatives.  array_unique() takes care of those.
$manydomains = array_unique(array_merge($manydomains, $alternatives));
