回覆客戶的電話號碼

Question

客戶可以擁有3個不同的電話號碼，我想根據陣列電話中的號碼從數據庫中檢索這些電話號碼。

function statsUserRing($phone, $link) 
{ 
    $i = 0; 
    $p1 = preg_replace('/[^0-9]/', '', $phone[0]); 
    $p2 = preg_replace('/[^0-9]/', '', $phone[1]); 
    $p3 = preg_replace('/[^0-9]/', '', $phone[2]); 

    while($get_stats = $link->get_object("SELECT REPLACE(telnr,'-', '') as telnr FROM ringupp WHERE telnr LIKE '%$p1%' OR telnr LIKE '%$p2%' OR telnr LIKE '%$p3%'")) 
    { 
     $i++; 
    } 

    return $i; 

} 

我試圖與一個客戶，有2個電話號碼登記。所以我的數組包含2個值，即這些數字。

這兩個數字在我的ringupp表中出現了16次，但是當我運行上面的代碼時，它將其計爲204154。爲什麼？

Answer 1

你可以使用只有SQL來實現這一點：

SELECT REPLACE(telnr,'-', '') as telnr 
FROM ringupp 
WHERE (telnr LIKE '%$p1%' AND '$p1' <> '') 
OR  (telnr LIKE '%$p2%' AND '$p2' <> '') 
OR  (telnr LIKE '%$p3%' AND '$p3' <> ''); 

Answer 2

您需要檢查空值和條件添加到基於你的查詢：

$query = "SELECT REPLACE(telnr,'-', '') as telnr FROM ringupp"; 

if($p1 != null) 
    $conditions = "telnr LIKE '%$p1%'"; 
if($p2 != null) 
    if($conditions != "") 
     $conditions = $conditions + " OR "; 
    $conditions = $conditions . "telnr LIKE '%$p2%'"; 
if($p3 != null) 
    if($conditions != "") 
     $conditions = $conditions . " OR "; 
    $conditions = $conditions . "telnr LIKE '%$p3%'"; 

if($conditions != "") 
    $query = $query . " WHERE " . $conditions + ";"

下面是檢查空值，並動態地構造一個SQL查詢的方法：

function statsUserRing($phone, $link) 
{ 
    $i = 0; 
    $count = 0; 

    $p[0] = preg_replace('/[^0-9]/', '', $phone[0]); 
    $p[1] = preg_replace('/[^0-9]/', '', $phone[1]); 
    $p[2] = preg_replace('/[^0-9]/', '', $phone[2]); 

    foreach ($p as $k => $v){ 
     if (!empty($v)){ 
      if ($count > 0){ 
       $wherelogic .= "OR telnr LIKE '%$v%' "; 
      } else { 
       $wherelogic .= "telnr LIKE '%$v%' "; 
      } 
      $count++; 
     } 
    } 

    $sql = "SELECT REPLACE(telnr,'-', '') as telnr FROM ringupp WHERE ".$wherelogic; 
    while($get_stats = $link->get_object($sql)) 
    { 
     $i++; 
    } 

    return $i; 

}
