如何在php-excel-reader中关闭Excel文件 [英] How to close excel file in php-excel-reader
问题描述
我正在使用php-excel-reader(从此开始)
I am reading two excel file, using php-excel-reader (From this)
读取第一行的两个文件后,我正在对其进行比较.如果它们是相同的,那么我会将文件中的包含附加到其他文件中.要写入文件,我正在使用此
After reading two files of 1st row, I am comparing it. If they are same then I am appending contain of on file to other. To write the file I am using this
现在,我想关闭一个文件,但是该功能在php-excel-reader中不可用
Now for doing this I want to close one file, but that function is not available in php-excel-reader
这是我的代码
compare file
{
$data = new Spreadsheet_Excel_Reader($filepath);
$data1 = new Spreadsheet_Excel_Reader($destinationfilepath);
}
unset($data);
unset($data1);
if($flag==0)
{
$excel = new ExcelWriter($destinationfilepath);
// read the source file
$finalarray= array();
for($m=1;$m<$sourcefilerowcount;$m++)
{
$charvalue='A';
$temprow=$m+1;
for($n=0;$n<$destinationcolnum;$n++)
{
$data = new Spreadsheet_Excel_Reader($filepath);
$finalarray[$n]=$data->val($temprow,$charvalue);
$charvalue++;
}
print_r($finalarray)."<br/>";
$excel->writeLine($finalarray);
}
推荐答案
不需要显式调用close()函数,因为该文件会在load()方法中自动关闭.如果查看定义了PHPExcel_Reader_Excel2007的Excel2007.php,您将看到:
There is no need to explicitly call close() function, because the file is automatically closed in the load() method. If you look at Excel2007.php, where PHPExcel_Reader_Excel2007 is defined, you'll see:
public function load($pFilename)
{
...
$zip = new ZipArchive;
$zip->open($pFilename);
...
$zip->close();
return $excel;
}
只需取消设置PHPExcel_Reader对象,数据就会从内存中删除:
Just unset your PHPExcel_Reader object, and the data will be removed from memory:
$objReader = PHPExcel_IOFactory::createReader('Excel2003XML');
$objPHPExcel = $objReader->load("Excel2003XMLTest.xml");
...
unset($objPHPExcel);
unset($objReader);
