如何在使用JSON数据的单个PHP foreach循环中包含所有下一页数据(How to include all next page data within single PHP foreach lo

如何在使用JSON数据的单个PHP foreach循环中包含所有下一页数据(How to include all next page data within single PHP foreach loop using JSON data)

我有一个JSON文件，每页限制50个项目，总共有818个项目。

我可以单独从前50个数据中提取数据。 我想知道是否有人知道如何拉出所有其他页面，所以他们都在一个PHP请求。

有没有人碰巧有一个功能的想法，或者如果有可能帮助解决这个问题的陈述？

结果数量有限的json示例（将显示50个）：

{ "count": 818, "max_per_page": 50, "current_page": 1, "links": [ { "href": "http://domain.com/?page=2", "rel": "next" }, { "href": "http://domain.com/", "rel": "prev" } ], "results": [ { "id": "1", "href": "http://domain.com/23385", "product_line": "A", "departures_start_date": "2015-01-01", "departures_end_date": "2017-12-24" }, { "id": "2", "href": "http://domain.com/22760", "product_line": "B", "departures_start_date": "2015-01-01", "departures_end_date": "2017-12-16" }, { "id": "3", "href": "http://domain.com/22790", "product_line": "C", "departures_start_date": "2015-01-01", "departures_end_date": "2017-12-30" }, ] }

I have a JSON file that limits me to 50 items per page, and there is a total of 818 for this one item.

I can pull the data from the first 50 individually. I'm wondering if anyone knows how I can pull all of the additional pages too so they're all in one php request.

Does anyone happen to have an idea for a function or if statement that could help sort this out?

Example piece of json with limited amount of results (50 would be shown):

{ "count": 818, "max_per_page": 50, "current_page": 1, "links": [ { "href": "http://domain.com/?page=2", "rel": "next" }, { "href": "http://domain.com/", "rel": "prev" } ], "results": [ { "id": "1", "href": "http://domain.com/23385", "product_line": "A", "departures_start_date": "2015-01-01", "departures_end_date": "2017-12-24" }, { "id": "2", "href": "http://domain.com/22760", "product_line": "B", "departures_start_date": "2015-01-01", "departures_end_date": "2017-12-16" }, { "id": "3", "href": "http://domain.com/22790", "product_line": "C", "departures_start_date": "2015-01-01", "departures_end_date": "2017-12-30" }, ] }

最满意答案

假设你使用file_get_contents检索你的数据，你可以试试这个：

$array = array(); $page = 1; while( $data = file_get_contents( '/Your/Path/Here?page=$page++' ) ) { $json = json_decode( $data, True ); #01 foreach( $json['results'] as $row ) $array[] = $row; }

在循环结束时，数组将包含所有元素：

[ [ "id": "1", "href": "http://domain.com/23385", (...) ], [ "id": "2", "href": "http://domain.com/22760", (...) ], (...) ]

如果你喜欢用对象而不是数组，你可以忽略True （＃01），然后每行可以通过$row->id而不是$row['id']进行调用

Assuming that you retrieve your data using file_get_contents, you can try this:

$array = array(); $page = 1; while( $data = file_get_contents( '/Your/Path/Here?page=$page++' ) ) { $json = json_decode( $data, True ); #01 foreach( $json['results'] as $row ) $array[] = $row; }

At the end of the loop, the array will contain all elements:

[ [ "id": "1", "href": "http://domain.com/23385", (...) ], [ "id": "2", "href": "http://domain.com/22760", (...) ], (...) ]

If you prefer objects instead of arrays, you can omit True (#01) and then each row will be callable through $row->id instead of $row['id']
