Tips and Notes
Note: The results from the server to the result returned by this function is not the same server.This array contains a numerical index, including the name index, or both.
Note: The results of this function are cached.Use clearstatcache () to clear the cache.
Tip: lstat () function and stat () function substantially similar.The only difference is that, if the file parameter is a symbolic link, then returns the status of the symbolic link (not the state of the symbolic link points to a file).
Examples
<?php
print_r(lstat("test.txt"));
?>
print_r(lstat("test.txt"));
?>
The code above will output:
