fstat

说明

array fstat ( resource handle )

获取由文件指针 handle 所打开文件的统计信息。本函数和 stat() 函数相似，除了它是作用于已打开的文件指针而不是文件名。

返回一个数组具有该文件的统计信息，该数组的格式详细说明于手册中 stat() 页面里。

例子 1. fstat() 例子
<?php // 打开文件 $fp = fopen("/etc/passwd", "r"); // 取得统计信息 $fstat = fstat($fp); // 关闭文件 fclose($fp); // 只显示关联数组部分 print_r(array_slice($fstat, 13)); ?>
上例的输出类似于：
Array ( [dev] => 771 [ino] => 488704 [mode] => 33188 [nlink] => 1 [uid] => 0 [gid] => 0 [rdev] => 0 [size] => 1114 [atime] => 1061067181 [mtime] => 1056136526 [ctime] => 1056136526 [blksize] => 4096 [blocks] => 8 )

注: 本函数不能作用于远程文件，被检查的文件必须通过服务器的文件系统访问。

Best way i found was to open the url into $data and make a temporary file with the contents of $data then get the fstats on the temporary file :).



OMG why? The only thing that will remain is the file size. You also download up to 1G file, which probably is not what you want.



To get size use PHP's function filesize() with URL wrappers or ask yourself via HTTP.

On Windows NT the typical array element names for the fstat function are:





dev


ino


mode


nlink


uid


gid


size


atime


mtime


ctime

Currently fstat() is indexed by name instead of by number like stat().





Example: $s_array=fstat($fp); print $s_array["mtime"];fclose($fp);
