How to recursively iterate through files in PHP?

Question

I have set up a basic script that is posting an array of paths to find template files inside them; currently it\'s only searching two levels deep and I\'m having some troubles g

Answer 1

Here is a generic solution:

function parseDir($dir, &$files=array(), $extension=false){

if(!is_dir($dir)){
    $info =  pathinfo($dir);
    // add all files if extension is set to false
    if($extension === false || (isset($info['extension']) && $info['extension'] === $extension)){
        $files[] = $dir;
    }
}else{
    if(substr($dir, -1) !== '.' && $dh =  opendir($dir)){
        while($file = readdir($dh)){
            parseDir("$dir/$file", $files, $extension);
        }
    }
}
 }

$files = array();
parseDir('components', $files, 'html');
var_dump($files);

OUTPUT

php parseDir.php 
array(7) {
  [0]=>
  string(25) "components/template2.html"
  [1]=>
  string(29) "components/side/template.html"
  [2]=>
  string(30) "components/side/template2.html"
  [3]=>
  string(36) "components/side/second/template.html"
  [4]=>
  string(37) "components/side/second/template2.html"
  [5]=>
  string(42) "components/side/second/third/template.html"
  [6]=>
  string(43) "components/side/second/third/template2.html"
}
