Dynamically listing files of type X

[Knouen]

$dir = opendir("../backup");

while(false !== ($file = readdir($dir))){
if(strpos($file, '.tgz',1)){
  echo '<a href="'.$dir.'/'.$file.'">Download tgz version of '.$file.'</a><br>';
}
}

while(false !== ($file = readdir($dir))){
if(strpos($file, '.gz',1)){
  echo '<a href="'.$dir.'/'.$file.'">Download gz version of '.$file.'</a><br>';
}
}

Am I on the right track with that one?  It's not working yet, thus the postign of code in this forum.

right track..

 

i would probably code like this..

 

(you could use an array for valid ext's but it depends on what your doing)

 

<?php
$dir = opendir("../backup");
while(false !== ($file = readdir($dir))){
$ext = strtolower(strrchr($file,'.'));
switch($ext)
{
case ".tgz":
  echo '<a href="'.$dir.'/'.$file.'">Download tgz version of '.$file.'</a><br>';
break;
case ".gz":
  echo '<a href="'.$dir.'/'.$file.'">Download gz version of '.$file.'</a><br>';
break;
}

}

?>

 

 

EDIT: sorry for bad formatting (not tabs) typed it live, thus untested

LOL spelt switch wrong (fixed)

Use glob():

 

<?php

echo "<pre>"; print_r(glob("*.gz")); echo "</pre>";

?>

 

 

Orio.

noted another problem

full script .. note the path (as your using the path you need to keep it as a string)

 

<?php

$dir = "../backup";
$DirOpen = opendir($dir);
while(false !== ($file = readdir($DirOpen)))
{
$ext = strtolower(strrchr($file,'.'));
switch($ext)
{
	case ".tgz":
	  echo '<a href="'.$dir.'/'.$file.'">Download tgz version of '.$file.'</a><br>';
	break;
	case ".gz":
	  echo '<a href="'.$dir.'/'.$file.'">Download gz version of '.$file.'</a><br>';
	break;
}
}


?>

 

as a side note i prefer readdir to glob.. (just do) i think its quicker may test later
