使用數組和str_replace ：

$remove = array('https://', 'http://www', 'https://', 'http://');

$test='http://stackoverflow.com/questions/18464723/how-do-i-remove-http-www-in-form';

echo str_replace($remove, '', $test);

您可以使用str_replace 。 使用此功能：

function http_www_remover($myString) {
  $return = str_replace( "https://www", "" , $myString);
  $return = str_replace( "http://www", "" , $myString);
  $return = str_replace( "https://" , "" , $myString);
  $return = str_replace( "http://" , "" , $myString);
  echo $return;
}

<form class="well" action="process.php">
<input type="text" name="q" placeholder="<? http_www_remover({$lang.placeholder});?>" x-webkit-speech>
<select name="t">
    <option value="domain"><? http_www_remover({$lang.domain});?></option>
    <option value="ip"><? http_www_remover({$lang.ip});?></option>
    <option value="nameserver"><? http_www_remover({$lang.nameserver});?></option>
</select>
<button type="submit" class="btn"><i class="icon"></i> <? http_www_remover({$lang.button});?></button>
