PHP - 组合多个数组

Question

我有两个函数，findNested用于查找字符串中的子字符串，findOverlap返回一个用于整数字符串的组合（$一致）字符串。我想要做的是创建一个数组或使用存储所有数据的数组（$ all_data）并返回组合信息，如果$ all_data [$ i] [＆＃39; linear_sequence＆＃39;]元素数组是嵌套的或重叠的，如果不使用它的行。 $ all_data数组中的每个元素看起来都是$ array1和$ array2。我认为使用array_merge_recursive来组合数据，但我不知道在哪里放置它可以合并多个$ all_data元素。但是现在它在新阵列中显示的值相同，并且不明白为什么。

    $array1=array ('linear_sequence' => 'QYDIKYTWNVPKIAPKS','E_ID' => 1416503, 'ant_source_organism_name' => 'Burkholderia pseudomallei K96243');

    $array2=array ( 'linear_sequence' => 'QQYDIKYTWNVPKIAPKSEN', 'E_ID' => 1409864, 'ant_source_organism_name' => 'Burkholderia pseudomallei K96243');



    function findNested($str1, $str2){
        $sl1 = strlen($str1);
        $sl2 = strlen($str2);
        if ($sl1>$sl2){
            if (strpos($str1,$str2) !== false) {
                return $str1;
            }
        }
        if ($sl2>$sl1){
            if (strpos($str2,$str1) !== false) {
                return $str2;
            }
        }
        return false;
    }

    function findOverlap($str1, $str2){
      $return = array();
      $sl1 = strlen($str1);
      $sl2 = strlen($str2);
      $max = $sl1>$sl2?$sl2:$sl1;
      $i=1;
      while($i<=$max){
        $s1 = substr($str1, -$i);
        $s2 = substr($str2, 0, $i);
        if($s1 == $s2){
          $return[] = $s1;
        }
        $i++;
      }
      if(!empty($return)){
        return $return;
      }
      return false;
    }

    function replaceOverlap($str1, $str2, $length = "long"){
      $min_overlap=9;
      $max_consensus=20;
      if($overlap = findOverlap($str1, $str2)){
        switch($length){
          case "short":
            $overlap = $overlap[0];
            break;
          case "long":
          default:
            $overlap = $overlap[count($overlap)-1];
            break;
        }   
        if (strlen($overlap)>=$min_overlap)  {
            $str1 = substr($str1, 0, -strlen($overlap));
            $str2 = substr($str2, strlen($overlap));
            $consensus = $str1.$overlap.$str2;
            if (strlen($consensus)<=$max_consensus){
                return $consensus;
            }
        }
      }
      return false;
    }
