Break if no file found in directory

[Peuplarchie]

Good day to you,

              I have a function which return an array of files.

              I would need it to break if there is no file in the directory.

 

Here is the code :

function compileList($extensions)
{
     if ($handle = opendir('.')) {
   while (false !== ($file = readdir($handle)))
      {
          $ext = strtolower(end(explode('.', $file)));
       
          if (in_array($ext, $extensions) AND $file != "." AND $file != "..")
              {
                  $files[$file]=implode(file($file));
              }
       }
  closedir($handle);
  }
  return $files;
         
}

 

Thanks !

What's your question...?

[Peuplarchie]

how if there is no file in the directory, instead of stating an error it would echo, no file in directory...

[Peuplarchie]

if (empty($files))
{
    echo 'No results';
    return null;
}
return

<?php
function compileList2($extensions){
  $extlist=implode(array_merge(array_map('strtolower',$extensions),array_map('strtoupper',$extensions)),',');
  $ret=glob('*.{'.$extlist.'}',GLOB_BRACE);
  if(!isset($ret) || (isset($ret) && count($ret)==0)){
    echo "No files found.";
    return NULL;
  } else {
    return $ret;
  }
}
echo print_r(compileList2(array('txt','php')),true);
echo print_r(compileList2(array('does_not_exist')),true);
?>
