5组数字，每组取一个组成不相同的5位数，大神

回复讨论(解决方案)

$d = explode(',', '012345678,013456789,023456789,012456789,023456789');$r = array();for($i=0; $i你可能需要有随机性的  
$d = explode(',', '012345678,013456789,023456789,012456789,023456789');$r = array();for($i=0; $i 
 
  我是想把所有能组成的5位数都显示出来，我没写清楚 
 
  循环 去重呗 
 
  
$d = array_map('str_split', explode(',', '012345678,013456789,023456789,012456789,023456789'));print_r(foo($d));function foo($d) {  $r = array_pop($d);  while($d) {    $t = array();    foreach(array_pop($d) as $k1=>$x) {      foreach($r as $k2=>$y) $t[] = "$x $y";    }    $r = $t;  }  return $r;}
