如何获得cakephp中循环的计数

[Book] => Array
                    (
                        [0] => Array
                            (
                                [id] => 48
                                [bookmaster_id] => 6
                                [condition] => not bad
                                [comments] => not bad
                                [isArchived] => 
                            )

                        [1] => Array
                            (
                                [id] => 50
                                [bookmaster_id] => 6
                                [condition] => ok
                                [comments] => ok
                                [isArchived] => 
                            )

                    )

我想获得arry book的数量值

Answer 1

假设这个数组叫做$ books

count($books)

除非你想在数据库中进行计数，否则使用find('count', array..)

Answer 2

您必须在数组中指定直接父索引： 如果您只是count($books);，则输出将为1

尝试

pr(count($books['Book']));
//Output 2
