PHP MySQL不更新數據庫

Question

我有似乎是一個語法問題，但我得到零錯誤。 首先，我測試了每個變量以確保它們被表單正確填充，所以這裏沒有問題。當「$ RespondentOrPetitioner」標有「R」或「P」，應該用這個來將數據添加到我的MySQL數據庫：

if ($RespondentOrPetitioner == "p") { 
    $sql = "REPLACE INTO alkouric_darling.customer(CaseNumber, PetitionerFirstName, PetitionerLastName, RespondentFirstName, RespondentLastName, RespondentAttorneyFullName, PetitionerAttorneyFullName) 
     VALUES ('$CaseNumber','$PetitionerFirstName', '$PetitionerLastName', '$RespondentFirstName', '$RespondentLastName','$RespondentAttorneyFullName','$AttorneyFullName')"; 
    mysqli_query($conn, $sql) or die(mysqli_error($conn)); 
} 

然而，這不更新DB這些字段「RespondentFirstName，RespondentLastName ，請願者姓名，請願者姓名，請願者姓名，「和」RespondentAttorneyFullName「。

我試圖複製/粘貼到一個單獨的文件只是小$ sql語句，它工作得很好，所以爲什麼它不能在我的文檔上工作？每個其他MYSQL代碼都適用於本文檔，但「IF」語句中的2則不適用。我花了好幾個小時試圖弄清楚這一點，並通過多個PHP語法檢查程序運行它，我仍然無法弄清楚，任何幫助，將不勝感激。

這裏是整個代碼：

<?php 
$servername = "99.99.99.99"; 
$username = "darling"; 
$password = "****"; 
$dbname = "alkouric_darling"; 
$conn = new mysqli($servername, $username, $password, $dbname); 

// Check connection 
if ($conn->connect_error) { 
    die("Connection failed: " . $conn->connect_error); 
} 

// enter San Bernardino court info 
if ($CourtCounty == "San Bernardino") { 
    $sql = "REPLACE INTO alkouric_darling.customer(CaseNumber, CourtCounty, CourtStreetAddress, CourtMailingAddress, CourtCity, CourtZip, CourtBranchName) 
      VALUES ('$CaseNumber', 'San Bernardino', '351 N. Arrowhead Ave', '351 N. Arrowhead Ave', 'San Bernardino', '92415-0245', 'Family Law')"; 
    mysqli_query($conn, $sql) or die(mysqli_error($conn)); 
} 

// enter Los Angeles court info

    $sql = "REPLACE INTO alkouric_darling.customer(CaseNumber, CourtCounty, CourtStreetAddress, CourtMailingAddress, CourtCity, CourtZip, CourtBranchName) 
      VALUES ('$CaseNumber','Los Angeles', '351 N. Arrowhead Ave', '351 N. Arrowhead Ave', 'San Bernardino', '92415-0245', 'Family Law')";

    mysqli_query($conn, $sql) or die(mysqli_error($conn)); 
}

mysqli_query($conn, $sql) or die(mysqli_error($conn)); 


mysqli_close($conn); 
?>

我想通了感謝WPCODER指着我在正確的方向。使用：

ON DUPLICATE KEY UPDATE
