PHPExcel reader – 需要帮助

我使用 PHPExcel从Excel表中读取数据并存储在MysqL表中,直到现在我可以上传.xls以及.xlsx文件,并且在上传xls后,我得到了下面的数据结构

name    start_date              end_date               city
one 11/25/2011 3:30:00 PM   11/29/2011 4:40:00 AM   Jaipur
two 10/22/2011 5:30:00 PM   10/25/2011 6:30:00 AM   Kota
three  3/10/2011 2:30:00 PM 3/11/2011 12:30:00 AM   Bikaner
                                                    chandigarh

现在我有一些问题,请建议我优化的方法

数据到db,下面是代码片段

$inputFileName = "test.xls";  
$inputFileType = PHPExcel_IOFactory::identify($inputFileName);  
$objReader = PHPExcel_IOFactory::createReader($inputFileType);  
$objReader->setReadDataOnly(true);  
/**  Load $inputFileName to a PHPExcel Object  **/  
$objPHPExcel = $objReader->load($inputFileName);  
$total_sheets=$objPHPExcel->getSheetCount(); // here 4  
$allSheetName=$objPHPExcel->getSheetNames(); // array ([0]=>'student',[1]=>'teacher',[2]=>'school',[3]=>'college')  
$objWorksheet = $objPHPExcel->setActiveSheetIndex(0); // first sheet  
$highestRow = $objWorksheet->getHighestRow(); // here 5  
$highestColumn = $objWorksheet->getHighestColumn(); // here 'E'  
$highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);  // here 5  
for ($row = 1; $row <= $highestRow; ++$row) {  
    for ($col = 0; $col <= $highestColumnIndex; ++$col) {  
    $value=$objWorksheet->getCellByColumnAndRow($col,$row)->getValue();  
        if(is_array($arr_data) ) { $arr_data[$row-1][$col]=$value; }  
    }  
}
print_r($arr_data);

并返回

Array
(
[0] => Array
    (
        [0] => name
        [1] => start_date
        [2] => end_date
        [3] => city
        [4] =>         
    )

[1] => Array
    (
        [0] => one  
        [1] => 40568.645833333
        [2] => 40570.5
        [3] => Jaipur
        [4] => 
    )
[2] => Array
    (
        [0] => two 
        [1] => 40568.645833333
        [2] => 40570.5
        [3] => Kota
        [4] => 
    )
[3] => Array
    (
        [0] => three
        [1] => 40568.645833333
        [2] => 40570.5
        [3] => Bikaner
        [4] => 
     )
  [4] => Array
    (
        [0] => 
        [1] => 
        [2] => 
        [3] => Chandigarh
        [4] => 
    )

)

我需要它

>每个excel表(即第一行)的标题变为数组($arr_data)的关键字
> rest成为数组的值.
>时间更改为一些整数值,这与excel表中的相同
>所有行中的数组的空白字段(即blank头文件列)应该被截断(这里[4])
>如果Excel表格的第一个字段(或某些的组合条件)
字段)不满足,那么该行不应该添加到数组中

即所期望的数组应该看起来像

Array  
    (  
    [0] => Array  
    (  
      [name] => one  
      [start_date] => 11/25/2011 3:30:00 PM  
      [end_date] => 11/29/2011 4:40:00 AM  
      [city] => Jaipur  
    )  
    [1] => Array  
    (  
      [name] => two  
      [start_date] => 10/22/2011 5:30:00 PM  
      [end_date] => 10/25/2011 6:30:00 AM  
      [city] => Kota  
    )  
    [2] => Array  
    (  
      [name] => three  
      [start_date] => 3/10/2011 2:30:00 PM  
      [end_date] => 3/11/2011 12:30:00 AM  
      [city] => Bikaner  
    )  
)

之后,我将数据存储到我的数据库中,使用所需数组上的MysqL操作.

>在db中存储上述数据还有其他简单的方法

注意：请不要参考手册(真的很糟糕)…只是告诉我方法名称..

更新

@Mark感谢您的解决方案,它帮助我很多,但仍然有一些问题

>当任何单元格为空时,如何处理excel sheet..bcoz中的空白单元格,然后显示通知

Notice: Undefined index: C in C:\xampp\htdocs\xls_reader\Tests\excel2007.PHP
on line 60
Notice: Undefined index: D in C:\xampp\htdocs\xls_reader\Tests\excel2007.PHP

而第60行是

foreach($headingsArray as $columnKey => $columnheading) { 
    $namedDataArray[$r][$columnheading] = $daTarow[$row]$columnKey];
}

>如何在检索完整数据数组之前设置条件,即如果我想要的是,如果第一列和第二列在任何行中为空/空白,则该行不应该添加到我们所需的数组中

谢谢

$sheetName = $objPHPExcel->getActiveSheet()->getTitle();

$objWorksheet = $objPHPExcel->setActiveSheetIndex(0);
$highestRow = $objWorksheet->getHighestRow();
$highestColumn = $objWorksheet->getHighestColumn();

$headingsArray = $objWorksheet->rangetoArray('A1:'.$highestColumn.'1',null,true,true);
$headingsArray = $headingsArray[1];

$r = -1;
$namedDataArray = array();
for ($row = 2; $row <= $highestRow; ++$row) {
    $daTarow = $objWorksheet->rangetoArray('A'.$row.':'.$highestColumn.$row,true);
    if ((isset($daTarow[$row]['A'])) && ($daTarow[$row]['A'] > '')) {
        ++$r;
        foreach($headingsArray as $columnKey => $columnheading) {
            $namedDataArray[$r][$columnheading] = $daTarow[$row][$columnKey];
        }
    }
}

echo '<pre>';
var_dump($namedDataArray);
echo '</pre><hr />';
