php laravel array foreach

json data information example:

pair : btcusdt

period (seconds) : 14400, 180, 1800, 21600, 259200, 300, 3600, 43200, 60, 604800, 7200, 86400, 900

Normally (on the site that provides data)

-btcusdt array items count = 4864 (all periods total)

-ltcusdt array items count = 4861 (all periods total)

-neousdt array items count = 4860 (all periods total)

but when you run the code in the dump screen

-btcusdt array items count = 4864

-ltcusdt array items count = 9724 (include btc array items)

-neousdt array items count = 14585 (include btc and ltc array items)

The code running process is taking too long when the number of pair increases...

What I do make mistakes ?
