如何从数组中排序所有数据

how can i crawl this array with a for loop or foreach , this is the content of a single array:

Array ( [0] => 1 ) Array ( [0] => 1 [1] => 2 ) Array ( [0] => 1 [1] => 2 [2] => 3 )

If you mean what I think you mean...

try this:

$tempArray = array();

foreach($myarray as $k => $v){
    foreach($v as $ke => $val ){
        $tempArray[] = $val;
      }
  }
  sort($tempArray);

Or if you want to avoid duplicates try:

 $temp = array_unique($myArray);
 sort($temp);
