Array: re-generate the key list?

[Full-Demon]

Hi,

 

I have a script that read information from a directory (using scandir()), and puts it in an array.

 

Now I want to filter out all files and unvalid directories (ie: '.' and '..'), so that I keep the normal/visible directories.

 

Than I loop through the array with a while(isset($array[$i])).

 

When I use array_filter() to filter out the unwanted files/directories from the array, it will also delete the keys. So the keys arent for instance: 0, 1, 2, 3, 4, 5  but: 2, 3, 5

 

When I loop through the array it will say: key 0 (in the beginning, when $i = 0) is not set and so it will stop.

 

How can I re-generate the keys so there wont be gaps between the numbers?

 

Thanks,

You can use a foreach loop instead of a for loop to cycle through the array, so instead of

<?php
for($i=0;$i<count($array);i++)
{
$element = $array[$i];
// do the work
}
?>

do

<?php
foreach($array as $element)
{
// do the work
}
?>

 

If you really need to resequence the array, you can write a function to do that:

<?php
$bad_array = array(1=>'xyz',10=>'abc');
function resequence($ary) {
  $tmp = array();
  foreach ($ary as $ele)
      $tmp[] = $ele;
  return ($tmp);
}
$array = resequence($bad_array);
echo '<pre>' . print_r($array,true) . '</pre>';
?>
