php array comparison implements the method of finding continuous numbers, php array search

The example in this article describes the method of php array comparison to implement the method of finding continuous numbers. Share it with everyone for your reference. The details are 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");
$data[]=array("01", "05", "14", "17", "22");
// 判断表格中3个以上的连续 
function checkAll($sourceArr2D) {
  $count = sizeof($sourceArr2D);
  for($i=0; $i<$count; $i++){
    check_h($sourceArr2D[$i], $i);//找寻水平方向
    if($i>0) {
      check_v($sourceArr2D, $i);// 找寻竖直方向
      check_l($sourceArr2D, $i);// 找寻/方向
      check_r($sourceArr2D, $i);// 找寻方向
    }
  }
}
// 判断水平方向
$h = array();// 保存水平方向上的搜寻结果
function check_h($arr, $rownum) {
  //sort($arr, SORT_NUMERIC);
  global $h;
  $flag = false;
  for($i=2; $i<6; $i++){
    if( $arr[$i-2]==$arr[$i]-2 ){
    // 因为数组内数字不重复且有序故可取巧
      if(!$flag) {
        $h[$rownum] = array($arr[$i-2], $arr[$i-1], $arr[$i]);
        $flag = true;
      }else{
        array_push($h[$rownum], $arr[$i]);
      }
    }
  }
}
// 判断竖直方向
$v = array();// 保存竖直方向上的搜寻结果
function check_v($sourceArr2D, $rownum) {
  global $v;
  for($i=0; $i<6; $i++){
    $val = $sourceArr2D[$rownum][$i];
    if( in_array($rownum...$val, $v) ){
      continue;
    }
    if( in_array($val,$sourceArr2D[$rownum-1]) && in_array($val,$sourceArr2D[$rownum+1]) ){
      array_push($v, ($rownum-1)...$val, $rownum...$val, ($rownum+1)...$val);
      $tmp = $rownum + 2;
      while( ($tmp < sizeof($sourceArr2D)) && in_array($val, $sourceArr2D[$tmp]) ){
        array_push($v, $tmp...$val);
        $tmp++;
      }
    }
  }
}
// 判断/方向
$l = array();// 保存/方向上的搜寻结果
function check_l() {
}
// 判断方向
$r = array();// 保存方向上的搜寻结果
function check_r() {
}
// 结束定义，开始应用
checkAll($data);
echo
//水平方向上的找寻：
print_r($h);
echo
//竖直方向上的找寻：
print_r($v);
echo
//方向上的找寻：
print_r($l);
echo
//方向上的找寻：
print_r($r);
