Formatting String Help

[MoFish]

Hi,

I have a textarea called registerDomain which i enter multiple domain names into (separated by a new line) e.g.

• www.google.com
• www.sky.com
• www.bt.com

I have the following code to get each of the domains and format them like

• google.com (lowercase without any spaces)
• sky.com (lowercase without any spaces)
• bt.com (lowercase without any spaces)

The below code I have works perfectly, however its awful to look at. I wondered if anyone could advise on a cleaner/more elegant way of achieving this.

Thanks,

	if (isset($_POST['submit'])) {
		$values = trim($_POST['registerDomain']);
		$array = explode("\n", $values);
		$array = array_filter($array, 'trim');
		
		foreach ($array as $line) {
			$domain = addslashes($line);
			$domain = preg_replace("/\r|\n/", "", $domain);
			$domain = strtolower($domain);
			$domain = str_replace("www.", "", $domain);
			$domain = str_replace(" ", "", $domain);

<?php

	// checks if the request exists and isnt empty
	if(isset($_POST['domains']) && !empty($_POST['domains'])){
      // using explode you can also put how mainy domains you want, like, explode("\n",$_POST['domains'], 3), you can change 3 for other numer but 
      // put the number of domains is optional
      $domains = explode("\n",$_POST['domains']);
      $validDomains = array();
      
      // check id there are valid domain
      foreach($domains as $domain){
        if(preg_match(/*some regerex expresion to check if element is a valid domain*/, $domain)){
        	$validDomain = strtolower($domain); 
			$validDomain = str_replace("www." , "" , $validDomain); 
			$validDomain = str_replace(" " , "" , $validDomain);  
          	array_push($validDomains, $validDomain)
        } else {
          	// handle error, like a error message
            // or continue with the loop without put the domain in $validDomains
          	continue
        }
      }
      
      // do something with $domains, that is a array
      // redirect to other page or something
    }  
      
?>

idk if you can store arrays in a database, but if you cant use this

<?php

	  if(isset($_POST['domains']) && !empty($_POST['domains'])){
      $domains = explode("\n",$_POST['domains']);
      $validDomains = array();
      
      foreach($domains as $domain){
        if(preg_match(/*regrex expresion*/, $domain)){
        	$validDomain = strtolower($domain); 
			    $validDomain = str_replace("www." , "" , $validDomain); 
			    $validDomain = str_replace(" " , "" , $validDomain);  
          array_push($validDomains, $validDomain);
        } else {
          	continue;
        }
      }
      
      // new code
      $domainString = implode(',', $validDomains);
      //store it in a databse
    }
      
?>

if you want to convert the string to a array, use this:

<?php

	// example
	$domainsString = obtainDomainsFromDatabase()
    $domainsArray = explode(',', $domainsString)
      
    // use $domainsArray

?>
