將CSV數據導入MySQL

Question

考慮以下來自“ NASDAQ.csv”的片段CSV數據

"Symbol,""Name"",""LastSale"",""MarketCap"",""ADR TSO"",""IPOyear"",""Sector"",""industry"",""Summary Quote"",";;
"FLWS,""1-800 FLOWERS.COM, Inc."",""2.9"",""81745200"",""n/a"",""1999"",""Consumer Services"",""Other Specialty Stores"",""http://www.nasdaq.com/symbol/flws"",";;
"FCTY,""1st Century Bancshares, Inc"",""4"",""36172000"",""n/a"",""n/a"",""Finance"",""Major Banks"",""http://www.nasdaq.com/symbol/fcty"",";;
"FCCY,""1st Constitution Bancorp (NJ)"",""8.8999"",""44908895.4"",""n/a"",""n/a"",""Finance"",""Savings Institutions"",""http://www.nasdaq.com/symbol/fccy"",";;

我正在嘗試將Symbol，Sector和Industry導入具有相應字段的MySQL表中：

$path = "NASDAQ.csv";
$row = 1;
if (($handle = fopen($path, "r")) !== FALSE) {
  while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
    $row++;
    $entries[] = $data ;
  }
  fclose($handle);
}

foreach ($entries as $line) {
  db_query("
     INSERT INTO us_stocks (symbol, name, sector, industry) 
     VALUES ('%s', '%s', '%s', '%s', '%s')",
     $line[0], $line[1], $line[6], $line[7]
  );
}

但是結果不是我所期望的。 在數據庫中，只有“符號”字段被填充，甚至沒有正確填充：

symbol      name  sector  industry
----------------------------------
Symbol,"Na
FLWS,"1-80
FCTY,"1st
FCCY,"1st

我究竟做錯了什么？

如果我print_r（$ entries），輸出看起來像

Array (
  [0] => Array(
    [0] => Symbol,"Name","LastSale","MarketCap","ADR TSO","IPOyear","Sector","industry","Summary Quote",;;
  )
  [1] => Array(
    [0] => FLWS,"1-800 FLOWERS.COM, Inc.","2.9","81745200","n/a","1999","Consumer Services","Other Specialty Stores","http://www.nasdaq.com/symbol/flws",;;
  )
  [2] => Array(
    [0] => FCTY,"1st Century Bancshares, Inc","4","36172000","n/a","n/a","Finance","Major Banks","http://www.nasdaq.com/symbol/fcty",;;
  )
)

[edit2]

根據建議，我已經刪除了CSV的第一行。 我現在有一種非常快又骯臟的方法來幾乎完成我想要的。 基本上，只要公司名稱中帶有“，Inc”，事情就會變得混亂。 因此，我只是將其“粘”到上面的名稱：$ data [1] = $ data [1]。 $ data [2]：

$path = "NASDAQ.csv";
$row = 1;
if (($handle = fopen($path, "r")) !== FALSE) {
  while (($data = fgetcsv($handle, 1000, ";;")) !== FALSE) {
    if ($row < 100) {
      $row++;
      $data = explode(',', $data[0]);
      if (substr($data[2], 0, 1) == ' ') {
        $data[1] = $data[1] . $data[2];
        unset($data[2]);
      }
      $entries[] = $data ;
    }
  }
  fclose($handle);
}

現在，print_r（$ entries）給出：

[0] => Array
    (
        [0] => FLWS
        [1] => "1-800 FLOWERS.COM Inc."
        [3] => "2.9"
        [4] => "81745200"
        [5] => "n/a"
        [6] => "1999"
        [7] => "Consumer Services"
        [8] => "Other Specialty Stores"
        [9] => "http://www.nasdaq.com/symbol/flws"
        [10] => 
    )

最后的問題：我不知道如何重新編號。 所以3成2，4成3，依此類推，所以輸出看起來像：

[0] => Array
    (
        [0] => FLWS
        [1] => "1-800 FLOWERS.COM Inc."
        [2] => "2.9"
        [3] => "81745200"
        [4] => "n/a"
        [5] => "1999"
        [6] => "Consumer Services"
        [7] => "Other Specialty Stores"
        [8] => "http://www.nasdaq.com/symbol/flws"
        [9] => 
    )

任何幫助將不勝感激！

Answer 1

我會說數據不是“真實” CSV。

“ FLWS”，“ 1-800 FLOWERS.COM，Inc。”，“ 2.9”應為：“ FLWS”，“ 1-800 FLOWERS.COM，INC。”，“ 2.9”-引號應換行各個字段之間用逗號分隔，通常不包裹數字字段。

根據您加載數據的方式，數據中的逗號可能會造成混淆。 （即FLOWERS.COM，INC”

順便說一句-如果它真的是CSV-請查看： http : //dev.mysql.com/doc/refman/5.1/en/load-data.html

正如Crontab所說，可能是引號有問題。 嘗試：

foreach ($entries as $line) {

  // Escape (see mysql_real_escape_string too) and remove double quotes
  foreach ($line as $k => $v) $line[$k] = mysql_escape_string(trim($v, '"'));

  // Rebuild array
  $line = array_values($line);

  db_query("
    INSERT INTO us_stocks (symbol, name, sector, industry) 
    VALUES ('%s', '%s', '%s', '%s', '%s')",
    $line[0], $line[1], $line[6], $line[7]
 );

}

PS：我不知道您是否已經在db_query()轉義了字符串。
