===================================

循环中将循环中的不同值赋给不同变量

$result = array();
   foreach ($query as $v){

    $result[] = $v->data;
    //echo $v->data;
   echo "<br>";

   }

-------------------

        //1、遍历$arrMemberList数组，通过每个成员的userid得到相应的个人年龄  //***********************
        //2、遍历$arrMemberList数组，通过每个成员的userid得到相应的个人是否有参报项目
        //3、如果成员报了项目，那么从teamform表中遍历出来所报项目名称
        //4、如果成员报了项目，取得队友名称
        //echo $userid;
        $memberage = array();
        $memberproject = array();
        $memberprojectname = array();
        $teammate = array();
        foreach ($arrMemberList as $value) {
            $memberage[] = $this->Common_model->get_memberage($value['userid']);
            $memberproject[] = $this->Team_model->get_memberproject($value['userid'],$teamid,$matchid);
            // $memberprojectname[] = $this->Team_model->get_memberprojectname($value['userid'],$teamid,$matchid);
            
            // $teammate[] = $this->Team_model->get_teammate($value['userid'],$teamid,$matchid);
        }
        $data['memberage'] = $memberage;
        $data['memberproject'] = $memberproject;
        // $data['memberprojectname'] = $memberprojectname;
        // $data['teammate'] = $teammate;

        $data['arrTeamMatch'] =$arrTeamMatch;

年龄在view层中输出方式

<?php
$n = 0; //$n用于数组下标

<?php

 foreach ($arrMemberList as $value) { ?>

<tr>

</tr>

<?php }?>
