多個數組 - 將值插入數據庫

Question

當前正在與朋友一起處理服務腳本。當我說服務腳本時，我的意思是它只會用於更新和向數據庫添加值。現在我的朋友已經把她所有的數據存儲爲數組了。

我已經成功地進入了其中一個數組，現在我很困惑我該怎麼做多個數組。因此，總而言之，這是一個關於如何將當前代碼重構爲更具動態性的問題。

另外請記住，她有數百個數組，這需要做到，因此它不像2或3它的字面數百。

我更新的代碼：（請閱讀評論）

$colors['Colors_All'] = array("Black","Charcoal"); // Add unique indexes 
$colors['Colors_Bright_All'] = array("Silver","White"); // Add unique indexes 

$AllArrays = get_defined_vars(); // Get all defined vars 
$Arrays = array(); // Set a default array 

foreach ($AllArrays as $varName => $value) { // Run through all the variables set in AllArrays 
     if(is_array($value) && $varName == 'colors') { // If array is colors then 
       $Arrays = array_merge($Arrays, $value); // Merge those arrays into the new array 
     } 
} 

var_dump($Arrays); 

$sql = "INSERT INTO `product_features` ("; // Create the initial query 

foreach ($Arrays as $column => $value) { // ForEach over the array 
     $sql .= "$column,"; // Use the Key Example : 'Colors_All and Color_Bright_All' as a column name 
} 

$sql2 = rtrim($sql, ","); // trim the initial "," from the columns at the end 
$sql2 .= ")"; // Close off the columns names 
$sql2 .= " VALUES "; 

foreach ($Arrays as $column => $value) { // This is where the problem starts -_- 
     foreach ($value as $key => $insert) { // Get the value 
       $sql2 .= "('$insert', '$insert'),"; // I need to have unique values here :(
     } 
} 

$finSQL = rtrim($sql2, ","); // Strip off the remaining "," 

而且我知道我不是綁定的參數，我一旦我得到的實際硬的東西出路。

現在做$ finSQL轉儲，當我得到這個：

string(152) "INSERT INTO `product_features` (Colors_All,Colors_Bright_All) VALUES ('Black', 'Black'),('Charcoal', 'Charcoal'),('Silver', 'Silver'),('White', 'White')" 

怎樣纔可以有獨特的價值在我插入查詢中的值？這是令我困惑的最後一部分。

Answer 1

嗯，我知道了「做」的序列化每一個陣列，通過實際的數組索引作爲唯一標識符，像這樣的數據庫：

<?php 
ini_set("error_reporting", E_ALL); 
ini_set("display_errors", TRUE); 

$conn = new MysqlI("HOST", "USER", "PASSWORD", "DATABASE" /*Optionally put the PORT NUMBER HERE : , 3306 */);  
$conn->set_charset('utf8'); // Always explicitly state the character encoding! 

$clearSQL = "TRUNCATE TABLE `product_features`;"; 
$clearNOW = $conn->prepare($clearSQL);// For updating this will delete all records in the table 
$clearNOW->execute(); 

$colors['Colors_All'] = array("Black", "Charcoal", "Pink", "Cheese", "Dog", "Punk"); // Add unique indexes 
$colors['Colors_Bright'] = array("Silver", "White", "Yellow", "Blue", "Indigo"); // Add unique indexes 
$colors['Colors_Bright_All'] = array("Silver", "White", "DarkYellow", "Dark_Pink",); // Add unique indexes 
$colors['Colors_Dark'] = array("Silver", "White", "DarkWE", "DarkCheese", "DarkBla"); // Add unique indexes 
$colors['Colors'] = array("Silver", "White", "DarkIDK", "DarKsome", "waDark", "dark"); // Add unique indexes 
$colors['Colors_Green'] = array("Silver", "White", "WAA", "WIWIW", "OMG", "Blood"); // Add unique indexes 
$colors['Colors_Red'] = array("Silver", "White", "IRI", "owow", "Darkness", "night"); // Add unique indexes 

$AllArrays = get_defined_vars(); // Get all defined vars 
$Arrays = array(); // Set a default array 

foreach ($AllArrays as $varName => $value) { // Run through all the variables set in AllArrays 
    if (is_array($value) && $varName == 'colors') { // If array is colors then 
     $Arrays = array_merge($Arrays, $value); // Merge those arrays into the new array 
    } 
} 

$sql = "INSERT INTO `product_features` (`ArrayIndex`, `ArrayValues`) VALUES "; // Create the initial query 

foreach ($Arrays as $ArrayIndex => $Arrayvalues) { // ForEach over the array 
    $sql .= "('$ArrayIndex','" . $mysqli->mysqli_real_escape_string(serialize($Arrayvalues)) . "'),"; // Use Array Index as the Unique Array Identifyer and Arrayvalues for the value 
} 

$finSQL = rtrim($sql, ","); // Strip off the remaining "," 

var_dump($finSQL); // Check the query 

$INSERT = $conn->prepare($finSQL); // Get query ready 
$INSERT->execute(); // Execute 

?> 

與數據庫中的結果是this

把$ Colors_Bright_All，$ Colors_Light_All放到最後一個數組中讓我們說$ finalArray並使用foreach循環遍歷該數組，然後執行你現有的foreach循環。

Answer 3

<?php 
function myInsert($myArray) 
{ 
    $colour_value = ""; 
    $stmt = $mysqli->prepare("INSERT INTO `product_features` (Colors_All) VALUES (?)"); 

    if ($stmt) { 
     $stmt->bind_param("s", $colour_value); 


     foreach ($myArrayas AS $value) { 
      $colour_value = $value; 
      $stmt->execute(); 
     } 

     $stmt->close(); 
    } 
} 


function myInsert($Colors_Bright_All); 
function myInsert($Colors_Light_All); 
?> 

編輯

<?php 
$newArray = array(); 

foreach($_GLOBALS as $val) 
{ 
    if(substr($val, 0, 7) == "Colors_") 
     myInsert($val); 
} 

?>

作爲解決您上述問題的請嘗試執行下面的代碼片段

例如

$finalarray=array(); 

    $Colors_Bright_All = array("Silver","White","Gold","Royal_Blue","Dodger_Blue","Deep_Sky_Blue","Deep_Green","Forest_Green","Bright_Green","Violet"); 

    $Colors_Light_All = array("Light_Gray","Silver","White","Gold","Dodger_Blue","Deep_Sky_Blue","Light_Blue","Bright_Green","LightGreen","Light_Green"); 

array_push($finalarray,'('.join(',',$Colors_Bright_All).')'); 
array_push($finalarray,'('.join(',',$Colors_Light_All).')'); 

    $value=join(',',$finalarray); 

$sql = "INSERT INTO `product_features` (Colors_All) VALUES ".$value; // Build the initial query 
$finSQL = rtrim($sql, ","); // Strip the last , so our mysql query doesn't goof up. 
$stmt = $conn->prepare($finSQL); 
$stmt->execute(); 

Answer 5

正如你在其他的答案被告知已，做一個嵌套數組是唯一明智的方法

$colors['bright'] = array("Silver","White","Gold"...); 
$colors['light'] = array("Light_Gray","Silver","White"...); 

foreach ($colors as $type => $array) { 

    // put your code here 

} 

，如果你需要更多的數據只是$type（因爲它不能被旁邊插入從極其模糊的問題告訴了），你可以用這個數據增加一個陣列以及

Answer 6

，如果你的代碼工作正常，然後更改

foreach ($Arrays as $column => $value) { // This is where the problem starts -_- 
     foreach ($value as $key => $insert) { // Get the value 
       $sql2 .= "('$insert', '$insert'),"; // I need to have unique values here :(
     } 
} 

到

foreach ($Arrays as $column => $value) { // The problem will be fixed :D 
     $sql2 .="("; 
     foreach ($value as $key => $insert) { // Get the value 
       $sql2 .= "'$insert',"; // You will have unique values here :D 
     } 
     $sql2 = chop($sql2,","); // strip the ending , 
     $sql2 .= "),"; 
}
