sprintf的使用參數的動態量

Question

只有當你解釋爲什麼這是不可能的/我將接受sprintf替代強烈不推薦

（下面的代碼）

我想從我的陣列插入dynamicaly數據到一個MySQL數據庫。我也試圖用sprintf進行試驗，這是我最近聽說的並且想要開始使用它。

如何從第二個foreach中獲取數據並通過sprintf將其存儲在查詢中？

陣列：

############################################################ 
         $csv->titles 
############################################################ 
Array 
(
    [0] => rating 
    [1] => title 
    [2] => author 
    [3] => type 
    [4] => asin 
    [5] => tags 
    [6] => review 
) 

############################################################ 
         $csv->data 
############################################################ 
Array 
(
    [0] => Array 
     (
      [rating] => 0 
      [title] => The Killing Kind 
      [author] => John Connolly 
      [type] => Book 
      [asin] => 0340771224 
      [tags] => 
      [review] => i still haven't had time to read this one... 
     ) 

    [1] => Array 
     (
      [rating] => 0 
      [title] => The Third Secret 
      [author] => Steve Berry 
      [type] => Book 
      [asin] => 0340899263 
      [tags] => 
      [review] => need to find time to read this book 
     ) 
... 

代碼我工作的：

foreach($dataArray as $key => $values){ 
     sprintf($query, eval(implode(",",$values))); 
    } 

：

$query = "CREATE TABLE IF NOT EXISTS XXX ("; 
$query .= "ID int(11) NULL AUTO_INCREMENT,"; 
$query2 = "SELECT * FROM XXX WHERE"; 

foreach($titlesArray as $keyTitles => $valuesTitles){ 
    $query .= cleanForShortURL($valuesTitles)." varchar(255),"; 
    $query2 .= cleanForShortURL($valuesTitles)." = '%s' AND "; 
} 
$query2 = substr($query2,0 ,-5); 
$query .= " PRIMARY KEY (`ID`) 
      ) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=0 "; 
$mysqli->query($query); 


foreach($dataArray as $key => $values){ 
    ################## PROBLEM HERE #################### 
} 

我嘗試之一萬一有人（從php.net）問：

function cleanForShortURL($toClean) { 
     $normalizeChars = array(
      'Š'=>'S', 'š'=>'s', 'Ð'=>'Dj','Ž'=>'Z', 'ž'=>'z', 'À'=>'A', 'Á'=>'A', 'Â'=>'A', 'Ã'=>'A', 'Ä'=>'A', 
      'Å'=>'A', 'Æ'=>'A', 'Ç'=>'C', 'È'=>'E', 'É'=>'E', 'Ê'=>'E', 'Ë'=>'E', 'Ì'=>'I', 'Í'=>'I', 'Î'=>'I', 
      'Ï'=>'I', 'Ñ'=>'N', 'Ò'=>'O', 'Ó'=>'O', 'Ô'=>'O', 'Õ'=>'O', 'Ö'=>'O', 'Ø'=>'O', 'Ù'=>'U', 'Ú'=>'U', 
      'Û'=>'U', 'Ü'=>'U', 'Ý'=>'Y', 'Þ'=>'B', 'ß'=>'Ss','à'=>'a', 'á'=>'a', 'â'=>'a', 'ã'=>'a', 'ä'=>'a', 
      'å'=>'a', 'æ'=>'a', 'ç'=>'c', 'è'=>'e', 'é'=>'e', 'ê'=>'e', 'ë'=>'e', 'ì'=>'i', 'í'=>'i', 'î'=>'i', 
      'ï'=>'i', 'ð'=>'o', 'ñ'=>'n', 'ò'=>'o', 'ó'=>'o', 'ô'=>'o', 'õ'=>'o', 'ö'=>'o', 'ø'=>'o', 'ù'=>'u', 
      'ú'=>'u', 'û'=>'u', 'ý'=>'y', 'ý'=>'y', 'þ'=>'b', 'ÿ'=>'y', 'ƒ'=>'f' 
     ); 

     $toClean  =  str_replace('&', '-and-', $toClean); 
     $toClean  = trim(preg_replace('/[^\w\d_ -]/si', '', $toClean));//remove all illegal chars 
     $toClean  =  str_replace(' ', '_', $toClean); 
     $toClean  =  str_replace('--', '-', $toClean); 

     return strtr($toClean, $normalizeChars); 
    }

避免EVAL只要有可能。嘗試vsprintf：

foreach($dataArray as $key => $values){ 
    vsprintf($query, $values); 
}
