[PHP] Re: Newbie: Question about filesize()
You also seem to have an extra equals. Your loop should read:
while (false != ($file=readdir($handle))){
It should come up as an error, but I'm not sure.

Hello There
I'm new to PHP and trying to code a function that reads all teh files out of

but it seems that the filesize() function doesn't work, here's the code so
far:
$handle = opendir ('images');
echo Files:brbr;
while (false !== ($file = readdir ($handle))) {
if($file != . $file != ..)
{
$file_s = filesize($file);
echo a href=images/$file$file/a Filesize:
$file_sbr;
}
}
closedir($handle);
and the output is somethingl ike this:
Files:
button_test_04.gif Filesize:
button_test_03-down.gif Filesize:
lilextras_01.gif Filesize:
(and so on)...
You see, there's no Filesize and I don't know why, please help me

RE: [PHP] Re: Newbie: Question about filesize()
that should be okay - it's to make sure that it is exactly equal to (as
opposed to equates to be equal to)
eg (0 === false) = false
(0 == false) = true

I think you could eliminate the false != in the while condition...
It should be just the same if you write
while (($file = readdir($handle)))
right?

No, that's the 'identical' operator, which returns true when its
operands are both equalivalent and of the same type:

Wrong, actually. If you have any files in that directory which have
names which would evaluate as false in PHP, then your way will fail on
them and you'll get a truncated directory listing. Do 'touch 0' in a
directory and give it a shot; you'll see what I mean.
However, the original example does the same thing, since it only checks
whether the result of the readdir() evaluates to FALSE, not whether it
actually is a boolean FALSE value. The correct way to do this is:
while (FALSE !== ($file = readdir($handle))) {
. . .
}
Note the !== instead of !=.
Hope this helps,
Torben
