如何从数组中提取子数据

Question

我在 PHP 中使用 SIMPLE HTML DOM Scraper 试图获得各种运动队的一些统计数据

index.php

$html = file_get_html("https://www.teamrankings.com/nfl/trends/ats_trends/");

foreach($html->find("tbody tr") as $h){
    $rows[] = $h->text();

Returns:

Array ( [0] => Green Bay 4-0-0 100.0% 12.8 +10.9 [1] => LA Chargers 4-1-0 80.0% -3.0 -0.1 [2] => Seattle 4-1-0 80.0% 6.8 +2.9 [3] => Pittsburgh 3-1-0 75.0% 7.8 +2.0

我想从中得到的是团队，然后是统计数据，例如索引 0 几乎有 5 个子数组索引。

[0] = green bay
[1] = 4-0-0
[2] = 100%
[3] = 12.8
[4] = +10.9

您可以看到主数组中有多个元素需要执行此操作。什么是最好的方法，或者我应该用刮刀以不同的方式来做？

获取 ->children()，这将是 td，然后遍历它们以获得 ->text()，可以使用 foreach 或 array_map 等

<?php
include 'simple_html_dom.php';

$html = file_get_html("https://www.teamrankings.com/nfl/trends/ats_trends/");

$rows = [];
foreach($html->find("tbody tr") as $tr) {
    $rows[] = array_map(function($td) {
        return trim($td->text());
    }, $tr->children());
}

print_r($rows);

/**
 * Array
(
    [0] => Array
        (
            [0] => Green Bay
            [1] => 4-0-0
            [2] => 100.0%
            [3] => 12.8
            [4] => +10.9
        )

    [1] => Array
        (
            [0] => LA Chargers
            [1] => 4-1-0
            [2] => 80.0%
            [3] => -3.0
            [4] => -0.1
        )
