删除重复行，如果两个变量匹配PHP

-1

我有两个变量$ faceplateInstalled和$ faceplateExists，我把它们打印成两列删除重复行，如果两个变量匹配PHP

Faceplate Exists Faceplate Instaled 
1       1 
1       0 
1       1 
0       0 
1       1 
1       0 
1       1 
1       1 
0       0 
0       0 
1       0

有没有一种方法，以消除在那里我一个相同的1和1项行？

这是一个查询使用：

"SELECT F.id AS faceplateId, PR.premiseId, ComposeAddressFromPAF(PR.postAddressId) AS fullAddress, " . 
      " IF(F.id IS NOT NULL, 1, 0) AS faceplateExists, " . 
      " IFNULL(F.installed, 0) AS faceplateInstalled, " . 
      " PR.siteId, S.NAME AS siteName " . 
      "FROM ho_crm_premise PR " . 
      " LEFT JOIN ho_faceplate F ON F.premiseId = PR.premiseId " . 
      " INNER JOIN bcube_site S ON S.SITEID = PR.siteId " . 
      "WHERE S.SITEID";

，这是全功能

function GetFaceplates($siteId) 
    { 
     $sSql = 
      "SELECT F.id AS faceplateId, PR.premiseId, ComposeAddressFromPAF(PR.postAddressId) AS fullAddress, " . 
      " IF(F.id IS NOT NULL, 1, 0) AS faceplateExists, " . 
      " IFNULL(F.installed, 0) AS faceplateInstalled, " . 
      " PR.siteId, S.NAME AS siteName " . 
      "FROM ho_crm_premise PR " . 
      " LEFT JOIN ho_faceplate F ON F.premiseId = PR.premiseId " . 
      " INNER JOIN bcube_site S ON S.SITEID = PR.siteId " . 
      "WHERE S.SITEID"; 

     if($siteId) 
     { 
      $sSql .= " AND PR.siteId = " . $siteId . " "; 
     } 

     $pResult = $this->ExecuteSQL($sSql); 
     return $pResult; 
    } 


$db = new DatabaseInfinity(); 

$action = $_REQUEST["action"]; 

//$action = "SEARCH"; // TEMPORARY 
$siteId = $_REQUEST["siteId"]; 

if($action == "SEARCH") 
{ 
    $faceplates = $db->GetFaceplates($siteId); 

    while($faceplate = FetchObject($faceplates)) 
    { 
     $tpl->newBlock("FACEPLATE"); 
     $tpl->assign("ID", $faceplate->faceplateId); 
     $tpl->assign("PREMISEID", $faceplate->premiseId ); 
     $tpl->assign("ADDRESS", $faceplate->fullAddress); 
     $tpl->assign("SITEID", $faceplate->siteId); 
     $tpl->assign("SITENAME", $faceplate->siteName); 
     $tpl->assign("FEXISTS", $faceplate->faceplateExists); 
     $tpl->assign("FINSTALED", $faceplate->faceplateInstalled); 
    } 
}

数据存储为数组？或者作为一个字符串......？ –

欢迎来到Stack Overflow！这个问题在信息上有点短暂。你可以分享你的尝试，以及你遇到了什么问题？ –

这会让所有人都猜到，*不是Sam吗？* - @JayBlanchard现在已经发布了一个答案，并且在事实*之后获得了某些内容*。 Oufff！ –

根据您的后期编辑，你可以改变你的查询，包括条件faceplateExists <> faceplateInstalled在外部查询到得到如下所需的结果

SELECT * FROM 
(
SELECT F.id AS faceplateId, PR.premiseId, 
ComposeAddressFromPAF(PR.postAddressId) AS fullAddress, " . 
      " IF(F.id IS NOT NULL, 1, 0) AS faceplateExists, " . 
      " IFNULL(F.installed, 0) AS faceplateInstalled, " . 
      " PR.siteId, S.NAME AS siteName " . 
      "FROM ho_crm_premise PR " . 
      " LEFT JOIN ho_faceplate F ON F.premiseId = PR.premiseId " . 
      " INNER JOIN bcube_site S ON S.SITEID = PR.siteId " . 
      "WHERE S.SITEID 
) XXX WHERE faceplateExists <> faceplateInstalled;

i'v完成了左加入，所以我没有一张桌子在哪里可以做到这一点，而且我不想删除记录我只想不显示他们 –

请不要在注释中转储代码 –

@MilosMarkovic，应该让人们早点知道，反正如果有帮助，请参阅编辑。 – Rahul
