关联操作后，dump($list)；
假如打印出来的数组像这样
array(4) {
[0] => array(5) {
["role_id"] => string(1) "2"
["user_id"] => string(1) "2"
["user"] => array(6) {
["id"] => string(1) "2"
["account"] => string(14) "654321@qq.com "
["username"] => string(0) ""
["password"] => string(32) "e10adc3949ba59abbe56e057f20f883e"
["status"] => string(1) "1"
["update_time"] => string(10) "1381567896"
}
["product"] => array（）//这里有数组的
}
[1] => array(5) {
["role_id"] => string(1) "2"
["user_id"] => string(1) "2"
["user"] => array(6) {
["id"] => string(1) "2"
["account"] => string(14) "654321@qq.com "
["username"] => string(0) ""
["password"] => string(32) "e10adc3949ba59abbe56e057f20f883e"
["status"] => string(1) "1"
["update_time"] => string(10) "1381567896"
}
["product"] =>NULL
}
[2] => array(5) {
["role_id"] => string(1) "2"
["user_id"] => string(1) "2"
["user"] => array(6) {
["id"] => string(1) "2"
["account"] => string(14) "654321@qq.com "
["username"] => string(0) ""
["password"] => string(32) "e10adc3949ba59abbe56e057f20f883e"
["status"] => string(1) "1"
["update_time"] => string(10) "1381567896"
}
["product"] => array（）
}
[3] => array(5) {
["role_id"] => string(1) "2"
["user_id"] => string(1) "2"
["user"] => array(6) {
["id"] => string(1) "2"
["account"] => string(14) "654321@qq.com "
["username"] => string(0) ""
["password"] => string(32) "e10adc3949ba59abbe56e057f20f883e"
["status"] => string(1) "1"
["update_time"] => string(10) "1381567896"
}
["product"] => NULL
}
}我可以过滤关联表 product = null 的数组么可以的话，$map应该怎么写？？？？？？？？？？
