    return $data; 
} 


$scraped_page = curl("http://champion.gg/champion/Riven"); 
$scraped_data = scrape_between($scraped_page, '],"experienceRate":[', '],"gameLength":['); 

echo $scraped_data; 

возвращает

46.34,48.94,50.84,53.51,55.29

Но я не могу показаться, чтобы выяснить, как изолировать 48,94 (второй) и 55,29 (в прошлом) значения.

Любая помощь будет высоко оценен

Answer 1

, если у вас есть строка с числами, разделенными с «» просто использовать взрываются(), чтобы разделить это в цифрах, то возьмите второй и последний из результирующего массива и вуаля, сделано.

Забавная подход к этой проблеме будет:

1. скачать и распаковать скрипт или его часть (например, с помощью AJAX ПОЛУЧИТЬ вызова)
2. выполнения Javascript Eval() на нем
3. получите таблицу данных как matchupData.championData ['experienceRate']

На самом деле это не php-решение, но чистое и меньшее копание в строках.
