A method of searching continuous number by comparing PHP array _php tips

The example in this article describes the method of comparing PHP arrays to find consecutive numbers. Share to everyone for your reference. as follows:

$data = Array ();
$data []= Array ("01", "02", "18", "29", "31", "32");
$data []= Array ("02", "09", "11", "22", "24", "27");
$data []= Array ("07", "16", "26", "27", "29", "31");
$data []=array ("04", "05", "07", "10", "13", "25");
$data []=array ("02", "04", "05", "08", "19", "22");
$data []=array ("03", "04", "15", "25", "26", "30");
$data []=array ("01", "03", "06", "12", "16", "32");
$data []=array ("01", "05", "14", "17", "22");
  To determine more than 3 consecutive function Checkall ($sourceArr 2D) {$count = sizeof ($SOURCEARR 2D) in the table; For ($i =0 $i < $count; $i + +) {check_h ($sourceArr 2d[$i], $i);/Find horizontal direction if ($i >0) {Check_v ($SOURCEARR 2d, $i )//Looking for vertical direction check_l ($SOURCEARR 2d, $i);/Find/Direction Check_r ($SOURCEARR 2d, $i);//Find Direction}}//judge horizontal direction $h = AR
  Ray ()//Save search results on horizontal direction function check_h ($arr, $rownum) {//sort ($arr, sort_numeric);
  Global $h;
  $flag = false; For ($i =2 $i <6; $i + +) {if ($arr [$i -2]== $arr [$i]-2) {//Because the number in the array is not duplicated and ordered so it can be tricky if (! $flag) {$h [$rownUM] = Array ($arr [$i-2], $arr [$i-1], $arr [$i]);
      $flag = true;
      }else{Array_push ($h [$rownum], $arr [$i]);
  }}//judge vertical direction $v = array ();//Save search results in vertical direction function Check_v ($SOURCEARR 2d, $rownum) {global $v;
    For ($i =0 $i <6; $i + +) {$val = $sourceArr 2d[$rownum] [$i];
    if (In_array ($rownum ... $val, $v)) {continue;  } if (In_array ($val, $SOURCEARR 2d[$rownum-1]) && In_array ($val, $SOURCEARR 2d[$rownum +1])) {Array_push ($v,
      ($rownum-1) ... $val, $rownum ... $val, ($rownum + 1) ... $val);
      $tmp = $rownum + 2; while ($tmp < sizeof ($SOURCEARR 2D)) && In_array ($val, $SOURCEARR 2d[$tmp])) {Array_push ($v, $tmp ... $va
        L);
      $tmp + +; }}//decision/Direction $l = Array ()//Search results on save/direction function check_l () {}//judgment Direction $r = Array ();//Save Direction Search Result function Chec
K_r () {}//end definition, start applying checkall ($data);
echo//Horizontal Direction Search: Print_r ($h);
echo//Vertical Direction Search: Print_r ($v);
echo//Direction Search: Print_r ($l); echo//Direction Search: Print_r ($r);
