Question

我有一个包含8列的CSV文件，我希望将任何列存储到数组中并使用它们。

例：货号，单元ID，SubscriberId，ActivationType，开始时间，结束时间，LicenseCount，产品编号

我该怎么做？

php代码：

class CSVparse
  {
  var $mappings = array();
  function parse_file($filename)
    {
    $id = fopen($filename, "r");
    $data = fgetcsv($id, filesize($filename));
    if(!$this->mappings)
       $this->mappings = $data;
    while($data = fgetcsv($id, filesize($filename)))
        {
         if($data[0])
           {
            foreach($data as $key => $value)
               $converted_data[$this->mappings[$key]] = addslashes($value);
            $table[] = $converted_data;
             }
         }
    fclose($id);
    print_r($table);
    }
  }
$csv = new CSVparse;
$csv->parse_file("sample.csv");

输出：

Array ( [0] => Array ( [Num] => 1 [UnitID] => 1 [SubscriberId] => 111 [ActivationType] => Standard [StartTime] => 8/5/2015 11:16 [EndTime] => 2015-09-05T11:16:00.7514332+04:30 [LicenseCount] => 2 [ProductId] => KISA1 ) [1] => Array ( [Num] => 2 [UnitID] => 1 [SubscriberId] => 222 [ActivationType] => Standard [StartTime] => 8/5/2015 11:16 [EndTime] => 2015-09-05T11:16:00.7514332+04:30 [LicenseCount] => 34 [ProductId] => KISA3 ) [2] => Array ( [Num] => 3 [UnitID] => 1 [SubscriberId] => 333 [ActivationType] => Standard [StartTime] => 8/5/2015 11:17 [EndTime] => 2015-09-05T11:17:27.6310205+04:30 [LicenseCount] => 12 [ProductId] => KISA6 ) [3] => Array ( [Num] => 4 [UnitID] => 1 [SubscriberId] => 444 [ActivationType] => Standard [StartTime] => 8/5/2015 11:17 [EndTime] => 2015-09-05T11:17:27.6310205+04:30 [LicenseCount] => 33 [ProductId] => KISA12 ) )

您可以将字段名称传递给该函数，并检查它所设置的字段。

[[NSOperationQueue mainQueue] addOperationWithBlock:^ {
   [self.countDown invalidate];
}];

为了使它更有用，你可以把它变成一个字段数组，并在条件中做class CSVparse { var $mappings = array(); function parse_file($filename, $fieldname = false) { $id = fopen($filename, "r"); $hdata = fgetcsv($id, filesize($filename)); if(!$this->mappings) $this->mappings = $hdata; while($data = fgetcsv($id, filesize($filename))) { foreach($data as $key => $value) { if ($fieldname) if ($this->mappings[$key] != $fieldname) continue; $converted_data[$this->mappings[$key]] = addslashes($value); } $table[] = $converted_data; } fclose($id); print_r($table); } } $csv = new CSVparse; $csv->parse_file("sample.csv", 'UnitID');。
