假设远程 SSH 连接是有效的,并且您在问题中使用的方法适用于单个文件,我相信您的操作顺序需要更正。
正如我在评论中提到的,您的代码似乎试图file_get_contents
在本地目录上使用,这是不允许的。看来您在 上也尝试了相同的操作$xmlstream
,必须按文件执行,而不是按目录执行。假设'C:\\xml\\Race_' . $value;
是一个目录C:\\xml\\Race_1
而不是文件。
资源验证的一些小问题和需要解决的 Windows 特定问题:
Windows 目录分隔符应该写成\\
(即使使用单引号),因为\
它是一个转义序列,它会导致\x \t \n \r \' \" \\
被视为特殊字符。
使用fopen($path, $mode)
时建议将b
标志指定为模式的最后一个字符,以确保文件是二进制安全的(逐字)并避免操作系统之间的歧义。或者,在 Windows 上指定t
要透明转换\n
为的模式\r\n
(仅适用于纯文本文件)。
$mode = 'rb'
(二进制安全读取)
$mode = 'rt'
(文本模式翻译阅读)
使用网络流时,建议测试流是否已成功写入其所有内容。我fwrite_stream
从 PHP 手册中提供了以下功能。

笔记
所有文件操作都将使用ssh2_auth_password
用户作为所有者/组来创建。您必须确保指定用户具有对所需目录的读写权限。
使用适当的文件掩码来确保所需的文件/目录权限
结果
C:\xml\Race_1\file1.xml size 9
C:\xml\Race_1\file2.xml size 11
array (
0 =>
array (
'filepath' => 'C:\\xml\\Race_1\\file1.xml',
'remote_filepath' => 'ssh2.sftp://Resource id #5/FTP/XML/Race_1/file1.xml',
'bytes' => 9,
),
