php - 獲取foreach結果總數

Question

我有一個foreach循環，它會在我的數據庫中執行搜索。我想獲得搜索返回的總行數。

目前，我有這樣的：

foreach ($stmt as $row) { 

    $search=$dbh->prepare("SELECT * FROM advertisement_clicks WHERE username=:username AND token=:token"); 
    $search->bindParam(":username",$userdata['id']); 
    $search->bindParam(":token",$row['token']); 
    $search->execute(); 
    echo $search->rowCount(); 

} 

這將打印出：00001100 - 我怎樣才能讓他們的總結果？ （在這種情況下，這將是2）

更妙的是，我怎麼能得到總的結果外 foreach循環？

循環外的代碼是這樣的：

$stmt = $dbh->prepare("SELECT * FROM advertisements WHERE status='2' AND fixed='1' AND fixed_expire>:time AND membershipFilter='0'"); 
$stmt->bindParam(":time",time()); 
$stmt->execute(); 
$f=$stmt->rowCount(); 

Answer 1

您可以按照下面做 -

$count = 0 ; 

foreach ($stmt as $row) { 

    $search=$dbh->prepare("SELECT * FROM advertisement_clicks WHERE username=:username AND token=:token"); 
    $search->bindParam(":username",$userdata['id']); 
    $search->bindParam(":token",$row['token']); 
    $search->execute(); 
    $count += $search->rowCount(); 

} 

echo $count ; 

Answer 2

$x = 0; 
foreach ($stmt as $row) { 

$search=$dbh->prepare("SELECT * FROM advertisement_clicks WHERE username=:username AND token=:token"); 
    $search->bindParam(":username",$userdata['id']); 
    $search->bindParam(":token",$row['token']); 
    $search->execute(); 
    echo $search->rowCount(); 
    $x++; 
} 
echo $x; 

Answer 3

通過像htis變量數一數：

$total = 0; 
foreach ($stmt as $row) { 

    $search=$dbh->prepare("SELECT * FROM advertisement_clicks WHERE username=:username AND token=:token"); 
    $search->bindParam(":username",$userdata['id']); 
    $search->bindParam(":token",$row['token']); 
    $search->execute(); 
    $total += $search->rowCount(); 


} 

$total將保留總價值。

Answer 4

以上都不是參與者真正瞭解他們寫了:)
此外，rowCount時不應該被用於這種目的，即使在這種特殊情況下的數字都沒有這麼高的代碼的含義

$total = 0; 
$query = "SELECT count(*) FROM advertisement_clicks 
      WHERE username=:username AND token=:token"; 
$search = $dbh->prepare($query); 
$search->bindParam(":username", $userdata['id']); 
$search->bindParam(":token", $row['token']); 

foreach ($stmt as $row) { 
    $search->execute(); 
    $total += $search->fetchColumn(); 
} 

它必須

此外，假設$ stmt是前面查詢的結果是，大部分你已經可以得到計數的其他查詢，使用GROUP BY操作的手段。 根本沒有這樣一個額外的循環
