PHP:Hapus digit didari belakang


Misalkan kita punya permasalahan memotong angka :

1310 menjadi 13

67891 menjadi 678

Yaitu menghapus 2 digit terakhir dari belakang.

Script PHP

<?

function getPotongAngka($angka){
$angka = (int)$angka;
$i_str = (string)$angka;
$angkax = substr($i_str, 0, -2);
return (int)$angkax;
}

$total = getPotongAngka(1310);
$total2 = getPotongAngka(44123);
echo “<br>Angka1 : “.$total;
echo “<br>Angka2 : “.$total2;
?>

Hasilnya :

Angka1 : 13
Angka2 : 441
