php读取csv数据保存到数组的方法,csv数组

本文实例讲述了php读取csv数据保存到数组的方法。分享给大家供大家参考。具体分析如下:

csv是常用的excel格式的替代品,很多时候我们导出数据是都会导成csv格式的,这样和excel没什么区别,下面的程序是要读取csv数据保存到数组我们要对数据进行操作,所以保存到数据,代码如下:

复制代码 代码如下:

$info=csvtoarray::open('teste.csv');
//echo '

'; <br>
//print_r($info); <br>
//echo '
';
foreach ($info as $c)
 {
  echo '学号:'.$c[0];
  echo '姓名:'.$c[1];
  echo '年龄:'.$c[2];
  echo '身高:'.$c[3].'
';
 }
 
 
 final class csvtoarray{
 
  /**
   * 把csv文件解析为一个数组返回
   *
   * @param string $file 要解析的csv文件路径 
   * @param char $delimiter csv文件里的内容分隔符 默认为;
   * @return array
   */
  public static function open($file, $delimiter = ';'){
   return self::ordenamultiarray(self::csvarray($file, $delimiter), 1);
  }
 
  private function csvarray($file, $delimiter)
  {
   $result = array();
   $size = filesize($file) + 1;
   $file = fopen($file, 'r');
   $keys = fgetcsv($file, $size, $delimiter);
   fseek($file,0);//这里原来的没有..自己加上..这样能读取到第一行的内容
   while ($row = fgetcsv($file, $size, $delimiter))
   {
    for($i = 0; $i     {
     if(array_key_exists($i, $keys))
     {
      $row[$keys[$i]] = $row[$i];
     }
    }
    print_r($row);
    $result[] = $row;
   }
 
   fclose($file);
 
   return $result;
  }
  private function ordenamultiarray($multiarray, $secondindex)
  {
   while (list($firstindex, ) = each($multiarray))
   $indexmap[$firstindex] = $multiarray[$firstindex][$secondindex];
   asort($indexmap);
   while (list($firstindex, ) = each($indexmap))
   if (is_numeric($firstindex))
   $sortedarray[] = $multiarray[$firstindex];
   else $sortedarray[$firstindex] = $multiarray[$firstindex];
   return $sortedarray;
  }
}
