[FILESYSTEM] Fetching every filename in a certain directory

[flaab]

Hello =)

 

I've a bunch of images en certain directories and I would like to display six of them in a random way.

 

So I need the make an 'ls' command on each one of them, and storing it's complete path into an Array position. And then, select some of the with the random function.

 

My problem is that I do not know how to make a dir / ls command in php and storing results.

 

How Can i do that?

 

Thanks in advance.

<?php
$dir    = '/tmp';
$files1 = scandir($dir);
$files2 = scandir($dir, 1);

print_r($files1);
print_r($files2);
?> 

 

Don't think it stores their complete path though.

 

This should help you:

Hi =)

 

Solved it with this. Returns the path to all files in a dir matching a regular expression.

 

<?php
function findfile($location='',$fileregex='') {
    if (!$location or !is_dir($location) or !$fileregex) {
       return false;
    }

    $matchedfiles = array();

    $all = opendir($location);
    while ($file = readdir($all)) {
    	/* Uncomment this block if you want subdir recursivity
       if (is_dir($location.'/'.$file) and $file <> ".." and $file <> ".") {
          $subdir_matches = findfile($location.'/'.$file,$fileregex);
          $matchedfiles = array_merge($matchedfiles,$subdir_matches);
          unset($file);
       }
      */
       if (!is_dir($location.'/'.$file)) {
          if (preg_match($fileregex,$file)) {
             array_push($matchedfiles,$location.'/'.$file);
          }
       }
    }
    closedir($all);
    unset($all);
    return $matchedfiles;
}
?>

 

Cheers.
