PHPExcel检查文件是否已保存

Question

我正在使用PHPExcel.我正在尝试将文件保存到目录(文件已保存).我可以确认文件已保存.我们$writer->save($filename);用来保存文件.
我尝试过

if( $writer->save($filename) ){
    echo "File successfully saved";
}

也喜欢

 if( $writer->save($filename) === true){
    echo "File successfully saved";
 }

任何人都可以帮忙吗？提前致谢.!

PHPExcel如果失败则抛出异常; 所以一个try/catch块

try {
    $writer->save($filename);
    echo "File successfully saved";
} catch (Exception $e) {
    echo 'ERROR: ', $e->getMessage();
    die();
}
