从 php 中的多维数组中删除值

Question

需要帮助，在我的函数底部，我试图从数组中删除一个值，所以当我从数组中取消设置一个值并使用同一变量执行 print_r() 时，它显示它已被删除，但是！当我使用相同的变量将其插入数据库时，它显示原始值，我不知道为什么......有什么想法吗？

public function updateProjectCommunity() {
        $data = fetch_query();
        $this->db->start_cache();
        $this->db->trans_start();
        $this->db->select('memberships');
        $this->db->from('org_projects_team');
        $this->db->where('project_id', $data->projectId);

        $response = $this->db->get()->result_array();
        $count = $this->db->count_all_results();
        
        if ($data->action == 'assign') {
            if ($count == 0) {
                $members = array();
                $members[$data->title][] = $data->person; 
                $members_sorted = array_unique($members);
                $members_update = array(
                    'project_id'  => $data->projectId,
                    'memberships' => JSON_encode($members_sorted)
                );
        
                $this->db->insert('org_projects_team', $members_update);
                    var_dump($members_sorted);  
            } else {
                $members = array();
                $members[$data->title][] = $data->person;
                $members_sorted = array_unique($members);
                $members_update = array(
                    'memberships' => JSON_encode($members_sorted)
                );
                $this->db->where('project_id', $data->projectId);
                $this->db->set('memberships', JSON_encode($members_sorted));
                $this->db->update('org_projects_team');
                var_dump($members_sorted);
            }
        } else {
            if ($count > 0) {
                $assigned_category = JSON_decode($response[0]['memberships'], true);
                foreach($assigned_category[$data->title] as $key => $value) {
                    if ($value = $data->person) {
                        if(is_array($assigned_category[$data->title])) {
                            unset($assigned_category[$data->title][$key]);
                            $update = $assigned_category;
                            $this->db->where('project_id', $data->projectId);
                            $this->db->set('memberships', JSON_encode($update));
                            $this->db->update('org_projects_team'); 
                        }
                    }
                }   
                print_r($assigned_category);            
                $error = array(
                    'status' => true,
                    'text' => "Successful"
                );          
            } else {
                $error = array(
                            'status' => false,
                            'text' => 'Error Occured'
                        );              
            }
            return $error;
        }

        $this->db->trans_complete();
        $this->db->flush_cache();
        
    }
