object(think\File)#3 (13) {
["error":"think\File":private] => string(0) ""
["filename":protected] => string(27) "C:\Windows\Temp\phpD9ED.tmp"
["saveName":protected] => NULL
["rule":protected] => string(4) "date"
["validate":protected] => array(0) {
}
["isTest":protected] => NULL
["info":protected] => array(5) {
["name"] => string(31) "微信图片_20170419101627.jpg"
["type"] => string(10) "image/jpeg"
["tmp_name"] => string(27) "C:\Windows\Temp\phpD9ED.tmp"
["error"] => int(0)
["size"] => int(65520)
}
["hash":protected] => array(0) {
}
["pathName":"SplFileInfo":private] => string(27) "C:\Windows\Temp\phpD9ED.tmp"
["fileName":"SplFileInfo":private] => string(11) "phpD9ED.tmp"
["openMode":"SplFileObject":private] => string(1) "r"
["delimiter":"SplFileObject":private] => string(1) ","
["enclosure":"SplFileObject":private] => string(1) """
} 最佳答案
