如何添加一个数组值的使用数组推动功能php

Question

我想解决这个分支树搜索，我想收集1个变量数组中的分支的所有值，并且问题是，分支函数返回当有很多值时，只有2个值，实际上我使用的是Codeigniter。

这是我的父功能：

$data['left'] = array(); 
    $data['right'] = array(); 
    $c=array(); 
    foreach ($root as $r){ 
     if ($r->branch_status=="L"){ 
      array_push($data['left'], array($r->member_id, $r->member_name, $r->member_phone)); 
      $c = $this->branch($r->member_id); 
      for ($i=0; $i<count($c); $i++){ 
       echo "array member : ".$c[$i][0]."<br>"; 
      } 
     } else if ($r->branch_status="R"){ 
      array_push($data['right'], array($r->member_id, $r->member_name, $r->member_phone)); 
      $c = $this->branch($r->member_id); 
      for ($i=0; $i<count($c); $i++){ 
       echo "array member : ".$c[$i][0]."<br>"; 
      } 
     } 
    } 

，这是我的分支功能：

public function branch($id){ 
    $br = array(); 
    $branch = $this->M_member->member($id); 
    foreach ($branch as $b){ 
     if (empty($b)){ 
      echo "empty member"; 
     } else{ 
      array_push($br,array($b->member_id,$b->member_phone)); 
      $this->branch($b->member_id); 
     } 
    } 
    for ($i=0; $i<count($br); $i++){ 
     echo "array member : ".$br[$i][0]." phone : ".$br[$i][1]."<br>"; 
    } 
    return $br; 
} 

Answer 1

的主要原因是$ BR分支函数的局部声明。这应该工作

public function branch($id, &$br=array()){ 

    $branch = $this->M_member->member($id); 

    foreach ($branch as $b){ 
     if (empty($b)){ 
      echo "empty member"; 
     } else{ 
      //array_push($br,array($b->member_id,$b->member_phone)); 
      $br[] = array($b->member_id,$b->member_phone); 
      $this->branch($b->member_id, $br); 
     } 
    } 
    return $br; 
}
