[DASAR PHP] Operator Aritmatika

Onesinus Tamba Selasa, 20 Maret 2018

Edit

Berikut adalah contoh penggunaan operator aritmatika didalam bahasa pemrograman PHP

<?php
 $var1 = 2; // deklarasi variable dengan nama var1 dengan nilai 2
 $var2 = 3; // deklarasi variable dengan nama var2 dengan nilai 3

 $var_tambah = $var1 + $var2; // membuat variable untuk menjumlahkan $var1 dan $var2
 $var_kurang = $var1 - $var2;// membuat variable untuk mengurangi $var1 dan $var2
 $var_kali = $var1 * $var2; // // membuat variable untuk mengkalikan $var1 dan $var2
 $var_bagi = $var1 / $var2; // membuat variable untuk membagi $var1 dan $var2
 $var_sisa_bagi = $var1 % $var2; // membuat variable untuk mendapat sisa dari pembagian $var1 dan $var2

 // menampilkan hasil
 echo $var_tambah . " ";
 echo $var_kurang . " ";
 echo $var_kali . " ";
 echo $var_bagi . " ";
 echo $var_sisa_bagi;
 ?>
