php list all files and sort alphabetically - php

Question

i'm using this function to list all files in a folder and its sub-folders
function printAll($dirName){
$dirs=array($dirName);
$files=array();
while($dir=array_pop($dirs)){
$handle=opendir($dir);
while($file=readdir($handle)){
if($file!='.' && $file!='..'){
$dest=$dir.'/'.$file;
if(is_file($dest)){
$files[]=$file;
echo $file;
}else{
$dirs[]=$dest;
}
}
}//end of 1st while
}//end of 2nd while
return $files;
}//end of function
printAll(getcwd());
But is there a way i can sort alphabetically the list of the filenames ?

Answer 1

You can use php's sort method, to perform sorting.
First, don't echo the file names on line 11.
//echo $file;
Next use this snippet:
$files_list = printAll(getcwd());
sort($files_list);
print_r( $files_list );

You're better off using scandir for this kind of thing. Due to the slightly odd thing you're requesting, it's inbuilt sorting won't finish the job (due to the grabbing the files in the directory below), but PHP's in built array sorting (in this case, natsort) should do the job fine.
function getDir($folder){
$folderFiles = scandir($folder);
$files = Array();
foreach($folderFiles as $filename){
if($filename==="." || $filename==="..") continue;
if(is_dir($folder."/".$filename)){
$files = array_merge($files, getDir($folder."/".$filename));
}else{
$files[] = $filename;
}
}
return $files;
}
$files = getDir("./");
natsort($files);
$files = array_values($files);
echo "<pre>";
print_r($files);
echo "</pre>";
