我使用PHPExcel创建文档，当我的文本文档中输入数据时，一切正常。这是我用来提供数据来创建Excel文档的内容。现在问题是，如果文本文档中没有任何数据，则在单元格中创建它为FALSE。有谁知道这是为什么？

答案 0 :(得分：1)
返回最长为length的字符串 - 从handle指向的文件中读取1个字节。如果在文件指针中没有要读取的数据，则返回FALSE。
如果文件为空，则函数返回false。在代码中包含验证，以在函数返回false时分配空字符串，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);
等等每个变量。
