PHP count of array returns more than it should? -

this code:

$dir = "img/"; $files = scandir($dir);  ($i=0; $i <= count($files); $i++) {      echo $files[$i]."<br/>"; } echo count($files); 

count of array returns value of 2 on empty array, cheched hidden files, 0 resault. can cause this? var_dump resault

array(7) {  [0]=> string(1) "."  [1]=> string(2) ".."  [2]=> string(8) "img1.gif"  [3]=> string(8) "img2.gif"  [4]=> string(8) "img3.jpg"  [5]=> string(8) "img4.png"  [6]=> string(8) "img5.png"  } 

its because array contain '.' & '..' 2 file names.

you can rid of using below code

$files = array_diff(scandir($dir), array('..', '.'));
