从数据库的一张表中获取了一个数组,为便于分析进行了切割,切割后数组如下:
<code>$arr = array( 0 => array( 'uid' => 5, 'username' => '', 'password' => '', 'user_status' => 1, 'login_number' => null, 'last_login_time' => null, 'last_login_ip' => null, 'nickname' => '', 'mobile' => '13863810574', 'realname' => '汪精卫', 'level' => '普通会员', 'trade_account' => '568050269', 'reg_time' => null, 'recom_account' => '243556', 'total' => null, 'is_apply' => '0', 'is_checked' => '0', 'haschild' => '1', ), 1 => array( 'uid' => '6', 'username' => '', 'password' => '', 'user_status' => '1', 'login_number' => null, 'last_login_time' => null, 'last_login_ip' => null, 'nickname' => '', 'mobile' => '18807556392', 'realname' => '周杰伦', 'level' => '普通会员', 'trade_account' => '12435356', 'reg_time' => null, 'recom_account' => '243556', 'total' => null, 'is_apply' => '0', 'is_checked' => '0', 'haschild' => '0', ), 2 => array( 'uid' => '7', 'username' => '', 'password' => '', 'user_status' => '1', 'login_number' => null, 'last_login_time' => null, 'last_login_ip' => null, 'nickname' => '', 'mobile' => '18316850912', 'realname' => '奥巴马', 'level' => '普通会员', 'trade_account' => '83475535', 'reg_time' => null, 'recom_account' => '834755351', 'total' => null, 'is_apply' => '0', 'is_checked' => '0', 'haschild' => '0', ), 3 => array( 'uid' => '8', 'username' => '', 'password' => '', 'user_status' => '1', 'login_number' => null, 'last_login_time' => null, 'last_login_ip' => null, 'nickname' => '', 'mobile' => '18879126845', 'realname' => '大卫', 'level' => '普通会员', 'trade_account' => '834755351', 'reg_time' => null, 'recom_account' => '154548', 'total' => null, 'is_apply' => '0', 'is_checked' => '0', 'haschild' => '1', ), 4 => array( 'uid' => '9', 'username' => '', 'password' => '', 'user_status' => '1', 'login_number' => null, 'last_login_time' => null, 'last_login_ip' => null, 'nickname' => '', 'mobile' => '18879701814', 'realname' => '黄建', 'level' => '普通会员', 'trade_account' => '154548', 'reg_time' => null, 'recom_account' => '568050269', 'total' => null, 'is_apply' => '0', 'is_checked' => '0', 'haschild' => '1', ), 5 => array( 'uid' => '10', 'username' => '', 'password' => '', 'user_status' => '1', 'login_number' => null, 'last_login_time' => null, 'last_login_ip' => null, 'nickname' => '', 'mobile' => '18879701814', 'realname' => '张科', 'level' => '普通会员', 'trade_account' => '9527', 'reg_time' => null, 'recom_account' => '568050269', 'total' => null, 'is_apply' => '0', 'is_checked' => '0', 'haschild' => '0', ), );</code>
现在想对该多维数组进行处理,规则为:当a键的recom_account的值等于b键的trade_account时,则a键值对为b键值对的直接子分类,当c键的recom_account等于a键的trade_account时,则c键值对为b键值对的间接子分类,每个键值对(分类)可以有多个直接子分类,但只对应一个直接父分类,也就是trade_account是唯一的,recom_account不是唯一的。期望返回的结果是:每个键值对增加一个count键,其值为所有直接子分类的个数,一个childlist键,其值为一个多维数组,记录子分类的所有信息,一个total_count键,其值为所有子分类的个数。haschild字段为1表示该分类有子分类(包括直接子分类与间接子分类),为0则没有子分类。如上面的数组,期望生成如下的格式。
