Goutte - Get inner values from $crawler->filter()

Ann*_*lee 8 php goutte domcrawler

I am using PHP 7.1.33 and "fabpot/goutte": "^3.2". My composer file looks like the following:

{
    "name": "ubuntu/workspace",
    "require": {
        "fabpot/goutte": "^3.2"
    },
    "authors": [

I am trying to get details by a time range from a webpage but struggle how to pass the $crawler-values to my final result array $res1Array.

I tried the following:

As you can see I am trying to create an $EVENT and push all wanted values as key value pairs inside. When I am finished I want to push it to the $resArray getting the following structure (values in this array() are just for structural purpose):

[

    latestURL => "test",

I currently get nothing back in my $res1Array.

I highly appreciate your replies!

Any suggestions why I get all this null values?

我冒昧地使用 OOP 稍微重写了您的代码，而不是让它保持功能，因为这样更容易专注于代码的较小部分。如果您需要的话，应该很容易将其转换为功能编码。

该类需要将date其格式化Jan2020为能够获取日历。

 $parser = new CalendarParser(date_create());
Run Code Online (Sandbox Code Playgroud)

要获取日历记录中某个日期范围内的事件 - 您需要$parser->getEventsBetweenDates()使用 astartDate和 an进行调用endDate。解析时不考虑时间，但如果需要，您可以添加它。这是一个例子：

$parser->getEventsBetweenDates(
   date_create_from_format('Y-m-d H:i:s', '2020-01-01 00:00:00'),
   date_create_from_format('Y-m-d H:i:s', '2020-01-02 23:59:59')

              我的评论是针对那些投反对票的人 - 不是专门针对你。恕我直言，在没有指出你认为错误的地方的情况下投反对票是很蹩脚的。我目前正在使用 `php 7.3` 但这应该不重要。我想你可能有一个旧版本的 `fabpot/goutte` - 我的是 `v4.0.0`。编辑：我刚刚注意到在你的问题中你指出你正在使用“^3.2”。可以更新到“4.0”吗？ (3认同)
