使用 str_replace() 并返回两个不同的版本

Question

我有一个文本区域，可以在其中输入多个域名来检查可用性。 在下面的脚本中，我用“-”替换空格。但我还想要一个不带“-”的域名版本。

举例来说，我输入：

一个好词

god-word

然后我希望脚本返回两者：

a-good-word

a-nother-

a-nother-god-word 还有：

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
}

如何在 PHP 中做到这一点？

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));

Answer 2

尝试：

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

Answer 3

如果你还没有让它工作，这里有一个粗略的函数来完成这项工作，而且它只会返回唯一的域

function getDomains($domaininput){
    function domainA($domaininput){
        $return = str_replace(" ","-",$domaininput);
        return $return;
    }
    function domainB($domaininput){
        $return = str_replace("-","",$domaininput);
        return $return;
    }
    $domaininput = str_replace("\n",",",$domaininput);
    $return = domainA($domaininput)."\n";
    $return .=domainB($return);
    $return = str_replace("\n",",",$return);
    $return = trim($return,'-,');
    $return = explode(",",$return);
    $return = array_unique($return);
    return $return;
}


$manydomains = getDomains($domaininput);
