[Resolved] Confuzed about $count

ajdegans

<?php
$dir_me = "images/me_room/"; //Dir to count files from
$count = 0; 
$count = $count - 2; //Minus 2 to remove the . and ..
if(is_dir($dir_me)) { 
   if($handle = opendir($dir_me)) { 
      while(($file = readdir($handle)) !== false) { 
         $count++; 
      } // end while
      closedir($handle); 
   } //end if
} //end if
?>

Im wondering why the $count MUST BE $count. As soon as i change it into something else the snippet stops functioning!? 😕 i dont get it... whats to magic about $count?:glare:

You're probably not changing "all" the $counts. Anything followed by a $ is a variable, and remember back to school.. the value of x (variable) always stays the same unless the variable is altered in it's visual form.

If you change x to y, but have already given x the value of 3, then you must make sure that you make all the x's, y's so it retains the same value.

So that said, make sure everything that says $count, is changed to what you wanted it to be.

What's wrong with:

<?php
$dir_me = "images/me_room/"; //Dir to count files from
$ajdegans = -2; //Minus 2 to remove the . and ..
if (is_dir($dir_me)) {
   if ($handle = opendir($dir_me)) {
      while (($file = readdir($handle)) !== false) {
         $ajdegans++;
      } // end while
      closedir($handle);
   } //end if
} //end if
echo $ajdegans; //print the file count
?>

I wouldn't say "quite obviously" because I took your snippet, and changed it to:

<?php 
$dir_me = "images/me_room/"; //Dir to count files from 
$dir_count = 0;  

$dir_count = $dir_count - 2; //Minus 2 to remove the . and .. 
if(is_dir($dir_me)) {  

   if($handle = opendir($dir_me)) {  

      while(($file = readdir($handle)) !== false) {  

         $dir_count++;  

      } // end while 
      closedir($handle);  

   } //end if 
} //end if 
?>

and it worked just fine for me... There was nothing "obvious" in your first post to indicate you had changed them all... AndrewWest was trying to be helpful, because sometimes we (as coders) overlook the most obvioius things, and going back to the very basics resolves a lot of problems... Anyhow, off the soap box now... Since it worked for me, I can't really help you other than to say it may be an issue with the server your files reside upon. Good luck finding your answer, I hope it gets resolved.

ajdegans

it was not my intention to be mean ... (really really 🙂 )

And yes youre right, the obviously is a bit misplaced... but think of this, wouldnt that be the first thing to think of? that you forget to change one...

So to get back to the topic. Im going to try laserlights code 🙂 and see if that works ( i noticed some diferences, Thanks for that)

Ill let you guys know if something comes up!😃

Well, that would be the obvious thing (touché), but you know as well as I do, it's sometimes easy to overlook the easiest thing... Or perhaps you made all of the changes, and inadvertently added a letter to one because you were typing furiously to meet a deadline... I don't think AndrewWest's intent was to belittle you in any way by suggesting the obvious...

I worked a helpdesk for 4 years, and you would be amazed at how many times people would complain because their monitor wouldn't turn on... They would get offended when I asked them to make sure the power cord was plugged in, and yet, 9 out of 10 times, that was the exact problem... It's the obvious things that screw us up the worst...

Defender youre so totally right.. anyway accept my apolagies 🙂

Again laserlight you helped me alot 😃

Your code works just perfect!

Thanks alot all for thinking with me!:p
