php mendapatkan data halaman web

Question

Saya ingin menulis pengumpulan data halaman web dengan kuki Saya tidak tahu cara menulis php. Bolehkah sesiapa membantu saya

Collection URL = “https://steamcommunity.com/tradeoffer/new/partnerinventory/?sessionid. =29475e48124c520cf70060dc&partner=76561198124311480&appid=433850& contextid =1”


cookie="sessionid=29475e48124c00690cf 8117047952%7C%7C512C7DB04B6A9719E1673019C075AA5ECF2B5032"


Bolehkah anda menulis contoh dengan penjelasan? Terima kasih. Kuki ini terhad masa. Jika ia tamat tempoh, tulis contoh sahaja
