Explode and return first element of array with one line of code

   $domain_parts = explode('.', preg_replace('/\s+/', '', $_GET['domain']));
   $sld = $domain_parts[0];

I am wanting to do the functionality of lines 1 and 2 into 1 line of code.

An example of what $_GET['domain'] provides is google.com

What is the cleanest way to do this in one line.

You can also do it without regular expression like this

$sld = str_replace(' ','',substr($_GET['domain'],0,strpos($_GET['domain'],'.')));

list($domain_parts) = explode('.', preg_replace('/\s+/', '', $_GET['domain']));

$domain_parts will contain the first element of the array.

You could get the second element like this:-

list(,$domain_parts) = explode('.', preg_replace('/\s+/', '', $_GET['domain']));

See list() for more details.

Or you could do this:-

$domain_parts = explode('.', preg_replace('/\s+/', '', $_GET['domain']))[0];

if you have PHP >= 5.4

You can try with list like

list($domain_parts) = explode('.', preg_replace('/\s+/', '', $_GET['domain']));

It will directly returns the $domain_parts[0].You can also try with strtok like

echo strtok(preg_replace('/\s+/', '', $_GET['domain']),  '.');

See this STRTOK
