但是最近没有这么写PHP，突然看一段代码懵了

@chmod($target, 0666 & ~umask());

 

注意一下，linux的 ~符号是代表home目录

建议如果需要做文件上传的话，可以单独使用下面的代码，是laravel的官方文件上传

public function move(string $directory, string $name = null)
    {
        if ($this->isValid()) {
            if ($this->test) {
                return parent::move($directory, $name);
            }

            $target = $this->getTargetFile($directory, $name);

            set_error_handler(function ($type, $msg) use (&$error) { $error = $msg; });
            $moved = move_uploaded_file($this->getPathname(), $target);
            restore_error_handler();
            if (!$moved) {
                throw new FileException(sprintf('Could not move the file "%s" to "%s" (%s).', $this->getPathname(), $target, strip_tags($error)));
            }

            @chmod($target, 0666 & ~umask());

            return $target;
        }

        switch ($this->error) {
            case \UPLOAD_ERR_INI_SIZE:
                throw new IniSizeFileException($this->getErrorMessage());
            case \UPLOAD_ERR_FORM_SIZE:
                throw new FormSizeFileException($this->getErrorMessage());
            case \UPLOAD_ERR_PARTIAL:
                throw new PartialFileException($this->getErrorMessage());
            case \UPLOAD_ERR_NO_FILE:
                throw new NoFileException($this->getErrorMessage());
            case \UPLOAD_ERR_CANT_WRITE:
                throw new CannotWriteFileException($this->getErrorMessage());
            case \UPLOAD_ERR_NO_TMP_DIR:
                throw new NoTmpDirFileException($this->getErrorMessage());
            case \UPLOAD_ERR_EXTENSION:
                throw new ExtensionFileException($this->getErrorMessage());
        }

        throw new FileException($this->getErrorMessage());
    }
