Muat naik imej pembangunan PHP memaparkan halaman yang sama

Banyak kali apabila kami memuat naik gambar, ia berada pada halaman yang sama dengan gambar yang dipaparkan Tidak perlu melompat ke halaman yang berasingan, jadi kami akan menggabungkan dua halaman bersama-sama dalam bahagian ini.

Petua: Anda perlu menyalin kod untuk dijalankan secara setempat
