file_exists
(PHP 3, PHP 4 )
file_exists -- Checks whether a file exists
Description
bool file_exists ( string filename)
Returns TRUE if the file specified by filename exists; FALSE otherwise.
This function will not work on remote files; the file to be examined must be accessible via the server's filesystem.
The results of this function are cached. See clearstatcache() for more details.
On windows use "//computername/share/filename" or "\\\\computername\share\filename" to check files on network shares.
这个函数不但对文件适用,而且对目录也适用.Top
