[RESOLVED] simple but unsolvable is_file problem :)

[knucklehead]

hi
i'm referring to THIS CONVERSATION and THIS ARTICLE and all that brought me to a new dilemma;
i have a simple code here;

<?
function SetShowErrors( $override = '' )
{
    $enable_key = "see_errors";
    $hide_key   = "hide_errors";

if ( isset($_GET[ $hide_key ]) )
{
    unset($_SESSION[ $enable_key ]);
    ini_set( 'display_errors' , 0 );
}

if ( isset($_SESSION[ $enable_key ]) OR isset($_GET[ $enable_key ]) OR $override )
{
    $_SESSION[ $enable_key ] = true;
    ini_set( 'error_reporting', E_ALL );
    ini_set( 'display_errors' , 1 );
}
} 
SetShowErrors();

$dir = "image/galerije/ups/".$_GET['id']."/";

if (is_dir($dir)) {
	if ($handle = opendir($dir)) {
        while (($file = readdir($handle)) !== false) {
            echo "filename: <u>".$file."</u>, filetype says: <u>".filetype($dir.$file)."</u>, but var_dump says: <u>";
			var_dump(is_file(readdir($handle)));
			echo "</u><br>";
			}
			closedir($handle);
	}
}
else
{
	echo "is NOT dir??!!";
}
?>

at the url http://ususur.org/test.php?id=4&see_errors where that page is located you can see this output;

filename: c.r.a.s.s..jpg, filetype says: file, but var_dump says: bool(false)
filename: ironing man.jpg, filetype says: file, but var_dump says: bool(false)
filename: zenska.jpg, filetype says: file, but var_dump says: bool(false)
filename: boh.jpg, filetype says: file, but var_dump says: bool(false)
filename: skare-paprikamen.jpg, filetype says: file, but var_dump says: bool(false)
filename: untitle me.jpg, filetype says: file, but var_dump says: bool(false) 

my questions are:

i) why my script reads only 5 files?? there are 8 files in that directory!!! look: http://www.ususur.org/image/galerije/ups/4/

ii) why filetype($dir.$file) says that it IS a file and var_dump(is_file(readdir($handle))) says FALSE?

iii) also, i'm not getting self directory and directory up ('.' and '..') in my listing! why??

all permissions on directory and files and are 777.

thanks for help!

The answer lies in your use of readdir 2 times in the loop.

while (($file = readdir($handle)) !== false) { << FIRST READ
echo "[snip]
var_dump(is_file(readdir($handle ))); << SECOND READ

That's why you get only 5 result lines for 8 files.

var_dump is telling you the output of the isfile review of the SECOND readdir.

var_dump which returns FALSE based on the return of that second filename. But what you REALLY want to test is is_file($dir.$filename), the same test you use for your filetype() test.

Suppose you have eight files in directory test

one.txt
two.txt
three.txt
four.txt
etc...
four

etc.

Your loop output checks

while ((one.txt= readdir([test.handle])) !== false) {
filename:<u> (one.txt)
filetype(test/one.txt) -- txt (found one.txt in directory test
var_dump says: FALSE
Because
var_dump(is_file(readdir($handle)))>>
var_dump(is_file(two.txt)) (second file in directory read)
no 'two.txt' file in your current working directory.

thank you nemonoman it was really helpful and when i replaced var_dump(is_file(readdir($handle ))) with is_file($dir.$file) i got what i need! the only thing i had to do to make my script work was to declare another variable which will add $file to $dir because php probably need full path to that image, right?
ok, i will consider this resolved 🙂
thanks!
