Berikut ini sistem informasi php akan berbagi tips dan trik mengenai program penjumlahan dengan php. Program penjumlahan ini terdiri dari form/formulir yang diinputkan oleh user kemudian tombol submit di tekan sehingga user atau pengguna dapat memperoleh hasi penjumlahan yang diinputkan. Berikut adalah source code nya :
Untuk membuat program penjumlahan dengan php, yang perlu dilakukan adalah membuat file input dan file aksi. berikut adalah kedua source code file input dan file aksi. simpan dalam format php. dan akses melalui localhost. Selamat Mencoba..
