Question

客户可以拥有3个不同的电话号码，我想根据阵列电话中的号码从数据库中检索这些号码。

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;

}

我正在尝试注册有2个电话号码的客户。所以我的数组包含2个值，即这些数字。

这两个数字在我的ringupp表中出现了16次，但是当我运行上面的代码时，它将它计为204154.为什么？

Answer 1

您只能使用SQL实现此目的：

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

您需要检查空值并根据以下内容为查询添加条件：

$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 + ";"

这是一种检查空值并动态构造SQL查询的方法：

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;

}
