PHPexcel数组。 帮助格式化数组，并清除NULL值的数组

我的电子表格总是有列B，C，D，E，F，G行3 =地址，姓名，电话，部门等等。来自单元格下面的数据（有些空的一些填充）1234 x street，1234 y street ，555-5555，HR等。所以如果我的数组看起来像这样：

[1] =>array( ['address1'] =>'1234 x street' ['name1'] =>'1234 y street' ['phone1'] =>'555-5555' ...etc ['department1'] =>'HR' [2] =>array( ['address2'] =>'1234 x street' ['name2'] =>'1234 y street' ['phone2'] =>'555-5555' ...etc ['department2'] =>'HR' 

我目前的代码是：

  <SNIP> $objReader->setReadDataOnly(true); $objPHPExcel = $objReader->load($inputFileName); $objWorksheet = $objPHPExcel->getActiveSheet(); if($header){ $highestRow = $objWorksheet->getHighestRow(); $highestColumn = $objWorksheet->getHighestColumn(); $headingsArray = $objWorksheet->rangeToArray('A1:'.$highestColumn.'1',null, true, true, true); $headingsArray = $headingsArray[1]; $r = -1; $namedDataArray = array(); for ($row = 2; $row <= $highestRow; ++$row) { $dataRow = $objWorksheet->rangeToArray('A'.$row.':'.$highestColumn.$row,null, true, true, true); if ((isset($dataRow[$row]['A'])) && ($dataRow[$row]['A'] > '')) { ++$r; foreach($headingsArray as $columnKey => $columnHeading) { $namedDataArray[$r][$columnHeading] = $dataRow[$row][$columnKey]; } } } } else{ $namedDataArray = $objWorksheet->toArray(null,true,true,true); 

}

研究表明，我可以使用以下方法之一，但我需要帮助把它放在一起：

  $column = 'IV'; $columnIndex = PHPExcel_Cell::columnIndexFromString($column); $adjustment = -2; $currentColumn = 'BZ'; $columnIndex = PHPExcel_Cell::columnIndexFromString($currentColumn); $adjustedColumnIndex = $columnIndex + $adjustment; $adjustedColumn = PHPExcel_Cell::stringFromColumnIndex($adjustedColumnIndex - 1);

我最终没有使用任何本地类的sorting片，降低开销，只是自己写如下：

  <?php //require 'FirePHPCore/fb.php'; This section was just to use FirePHP so I could see the JSON output without using html. //ob_start('ob_gzhandler'); //FB::info('Hello, FirePHP'); //FB::log('Log message'); //FB::info('Info message'); //FB::warn('Warn message'); //FB::error('Error message'); require_once dirname(__FILE__) .

现在我只需要获取钩子，以便当dropzone.js完成时它将自动填充.js表单。
