我需要检查是否使用PHPSpreadsheet打开了excel文件。
我想到了将$writer->save(file_name)这一行处理为if else条件的解决方案，但仍然无法正常工作。
if($writer->save(file_name){
//file is open
}else{
//file is not open
}
我还能做什么来解决我的问题？

我需要检查是否使用PHPSpreadsheet打开了excel文件。
检查文件是否打开并不是真正有用的，因为打开/关闭状态可能随时更改，或者失败可能是由其他文件系统问题引起的。
您需要做的是处理 文件操作期间的失败：
try {
$writer->save(file_name);
}
catch (Exception $e) {
echo 'Unable to save file. Please close any other applications(s) that are using it: [", $e->getMessage(), "]\n";
}

在以下情况下，@ terry-carmen的回答将是错误的：
$writer->save()将尝试unlink()文件。（位于：“ \ vendor \ phpoffice \ phpspreadsheet \ src \ PhpSpreadsheet \ Writer \ Xlsx.php ”）
public function save($pFilename)
{
if ($this->spreadSheet !== null) {
// garbage collect
$this->spreadSheet->garbageCollect();
// If $pFilename is php://output or php://stdout, make it a temporary file...
$originalFilename = $pFilename;
if (strtolower($pFilename) == 'php://output' || strtolower($pFilename) == 'php://stdout') {
$pFilename = @tempnam(File::sysGetTempDir(), 'phpxltmp');
if ($pFilename == '') {
$pFilename = $originalFilename;
}

主要更改：
1）使用try catch通过unlink（）将“ Resource Unavailable”错误处理为异常，以便在某些应用程序正在使用文件时不显示错误 使用取消链接将其删除。
if (file_exists($pFilename)) {
// Added by muhammad.begawala@gmail.com
// '@' will stop displaying "Resource Unavailable" error because of file is open some where.
// 'unlink($pFilename) !== true' will check if file is deleted successfully.
// Throwing exception so that we can handle error easily instead of displaying to users.
if (@unlink($pFilename) !== true) {
throw new WriterException('Could not delete file: ' . $pFilename . ' Please close all applications that are using it.');
}
}
2）如果成功创建文件，否则$ writer-> save（'hello world.xlsx'）将返回TRUE，否则引发异常。
用法：
try {
$writer->save('hello world.xlsx');
echo 'File Created';
}
catch (Exception $e) {
echo $e->getMessage(); // Will print Exception thrown by save()
}
