Php 如何在特定数组中存储列csv文件

我有一个8列的CSV文件，我想将任何列存储到一个数组中并使用它们

示例：Num、UnitId、SubscriberId、ActivationType、StartTime、EndTime、LicenseCount、ProductId

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 ) )

您可以将字段名传递给函数，并对设置的字段进行检查

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');

为了使其更可用，您可以将其设置为字段数组，并在条件中执行

array\u search（）

。

代码的输出将为所有列返回此值：array（[0]=>array（[Num]=>1）[1]=>array（[Num]=>2）[2]=>array（[Num]=>3][3]=>array（[Num Num]=>4））编辑以修复错误-密钥需要映射到字段名
