使用str_replace（）並返回兩個不同的版本

Question

我有一個textarea，我可以鍵入多個域名來檢查可用性。 在我的腳本中，我將空格替換爲「 - 」。但我也想要一個沒有「 - 」的域名版本。

說，例如，我輸入：

了良好的口碑

一個諾特爾神字

然後我想腳本返回兩個：

A-好詞

a-nother-god-word

並且：

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做什麼？

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

嘗試：

$domaininput = (isset($_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 
}

，如果你沒有得到它仍然在這裏工作的待辦事項任務粗功能，再加上它只會返回唯一域

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);
