当文本为空时，PHPExcel数据在单元格中发送FALSE？
我使用PHPExcel创build一个文档，当有数据input到我的文本文档中时，一切正常。 这是我用来提供数据来创buildExcel文档。 现在的问题是，如果文本文档中没有任何数据，它会在单元格中使用FALSE创build它。 任何人都知道这是为什么？

从fgets文档 ：
返回长度最长的string – 从句柄指向的文件中读取1个字节。 如果在文件指针中没有更多的数据要读取，则返回FALSE。
如果文件是空的，函数返回false 。 在代码中包含一个validation，以便在函数返回false时分配一个空string，如下所示：
$myFile=fopen("DATA/Spo.txt","r") or exit("Can't open file!"); $Spo = fgets($myFile); if ($Spo === false) $Spo = ''; fclose($myFile);
等等每个variables。
