I assume the answer is yes.
I try to write readSubdir function read all files
in all sub-directories.
<?php
readSubdir("Documents/2005");
function readSubdir($dirPath) {
$dirPointer = opendir($dirPath);
while (($file = readdir($dirPointer)) != false) {
if ($file == "." || $file == "..")
continue;
if (filetype($file) == "dir") {
# if (is_dir($file) == true) {
# if (strcmp(filetype($file), "dir") == 0) {
readSubdir($file);
} else {
echo "file is $file\n";
}
}
closedir($dirPointer);
}
?>
You see above I tried to used three different methods
to check a directory.
* 1st way I used filetype() function
I got errors
Warning: filetype(): Lstat failed for 05 in /MyPath/myreaddir.php on line 13
file is 05
Warning: filetype(): Lstat failed for 06 in /MyPath/myreaddir.php on line 13
file is 06
Where 05, 06 are sub-directories, it fails return a string "dir"! Why?!
2nd way I used is_dir() function, but it fails return true! Why?!
file is 05
file is 06
3rd way I used strcmp for return from file type, it gets the same
error as 1st way.
But when I tried to use
var_dump(is_dir("Documents/2005/05"));
var_dump(filetype("Documents/2005/05"));
I got the CORRECT display
bool(true)
string(3) "dir"
Can anyone out there help solve this mystery?
Thank Q very much in advance!
