问题解析出来的数据不完整，有为空的字段,网上查了下说是在php5.2.8 中存在bug，解决办法是使用自定义函数，代码如下：

function __fgetcsv(& $handle, $length = null, $d = ',', $e = '"') {

     $d = preg_quote($d);

     $e = preg_quote($e);

     $_line = "";

     $eof=false;

     while ($eof != true) {

         $_line .= (emptyempty ($length) ? fgets($handle) : fgets($handle, $length));

         $itemcnt = preg_match_all('/' . $e . '/', $_line, $dummy);

         if ($itemcnt % 2 == 0)

             $eof = true;

     }

     $_csv_line = preg_replace('/(?: |[ ])?$/', $d, trim($_line));

     $_csv_pattern = '/(' . $e . '[^' . $e . ']*(?:' . $e . $e . '[^' . $e . ']*)*' . $e . '|[^' . $d . ']*)' . $d . '/';

     preg_match_all($_csv_pattern, $_csv_line, $_csv_matches);

     $_csv_data = $_csv_matches[1];

     for ($_csv_i = 0; $_csv_i < count($_csv_data); $_csv_i++) {

         $_csv_data[$_csv_i] = preg_replace('/^' . $e . '(.*)' . $e . '$/s', '$1' , $_csv_data[$_csv_i]);

         $_csv_data[$_csv_i] = str_replace($e . $e, $e, $_csv_data[$_csv_i]);

     }

     return emptyempty ($_line) ? false : $_csv_data;

}
