php - 使用嵌套 foreach 循环从 mysql 记录集创建多维数组

Question

有人可以告诉我使用哪种语法从 mysql 记录集构建“目录”数组吗？谢谢!

$directory = array();

foreach ($resultSetFromDB as $row){

    foreach ($row as $field => $value){

        $directory[$field][] = $value;

    }
}

我可以打印 $field 和 $value，没问题

试试这个:

$directory = array();

foreach ($resultSetFromDB as $i => $row) {

    foreach ($row as $field => $value) {

        $directory[$i][$field] = $value;

    }
}
