How to sort this array by type (dir first and then files)

Question

I wanna know how to sort arrays like this:

$array[] = Array (
    'name' => '/home/gtsvetan/public_html/presta/cms.php'
    'type' => 'text/x-php'
    'size' => 1128
    'lastmod'  => 1339984800
);
$array[] = Array (
    'name' => '/home/gtsvetan/public_html/presta/docs/'
    'type' => 'dir'
    'size' => 0
    'lastmod' => 1329253246
);

I wanna to sort it first by type (folders first and then files) and then alphabetical. But I don't know how to sort it.

Best regards, George!

Answer 1

you can use usort()

In compare function you do two comparisions on name & type - something like below:

function compare_f($a,$b) {

 if($a['type']=='dir'&&$b['type']!='dir') return 1;
 if($a['type']!='dir'&&$b['type']=='dir') return -1;
 if(substr($a['name'],-1,1)=='/') $a['name']=substr($a['name'],0,-1);
 if(substr($b['name'],-1,1)=='/') $b['name']=substr($b['name'],0,-1);
 $af_array=explode('/',$a['name']);
 $a_name=$af_array[count($af_array)-1];
 $bf_array=explode('/',$b['name']);
 $b_name=$bf_array[count($bf_array)-1];

 if($a_name>$b_name) 
    return 1;
  return -1;

}

usort($array,'compare_f');
