PDO查詢連續

      "; 
     } 

出於某種原因將兩次，我的查詢將自身插入兩次....我不知道這是否是if語句檢查，如果rowCount時大於0，這是個問題還是我瞎了點什麼？

編輯：編輯後顯示$ _POST變量。

不知何故你正在執行查詢兩次，因爲下面是我嘗試使用的代碼，它總是插入一行。

還檢查每個包含索引文件。或者重新啓動mysql。

<?php 
$array = array(
     ":txn_id" => "1", 
     ":payer_firstname" => "2", 
     ":payer_lastname" => "3", 
     ":payer_business" => "4", 
     ":payer_email" => "5", 
     ":payer_country_code" => "6", 
     ":payer_country" => "7", 
     ":payer_state" => "8", 
     ":payer_city" => "9", 
     ":payer_zip" => "10", 
     ":payer_street" => "11", 
     ":payer_phone" => "12", 
     ":payer_type" => "13", 
     ":item_name" => "14", 
     ":item_number" => "15", 
     ":payment_amount" => "16", 
     ":payment_status" => "17", 
     ":payment_currency" => "18", 
     ":date" => "19", 
     ":ip" => "20" 
); 

$conn = new PDO('mysql:host=localhost;dbname=test', "root", "123456"); 

$prepare = $conn->prepare("INSERT INTO transactions (t_num, 
t_payer_firstname, t_payer_lastname, t_payer_business, t_payer_email, 
t_payer_country_code, t_payer_country, t_payer_state, t_payer_city, 
t_payer_street, t_payer_zip, t_payer_phone, t_payer_type, t_name, 
t_hex, t_price, t_status, t_currency, t_date, t_ip) VALUES (:txn_id, 
:payer_firstname, 
:payer_lastname, 
:payer_business, 
:payer_email, 
:payer_country_code, 
:payer_country, 
:payer_state, 
:payer_city, 
:payer_zip, 
:payer_street, 
:payer_phone, 
:payer_type, 
:item_name, 
:item_number, 
:payment_amount, 
:payment_status, 
:payment_currency, 
:date, 
:ip) "); 

$execute = $prepare->execute($array); 

if ($execute) { 
    echo 'good'; 
}
