点后如何爆炸价格

Question

<?
$price = "75";
$kdv = $price*18/100; 
$kdvdahil = $kdv+$price; 

$kdvdahil produces 88.5

?>

我只想将$ kdvdahil分解为两个部分：88和5

我该怎么办？

Answer 1

然后简单地使用explode()

<?php
# with explode
$number = explode('.',88.5);
echo "integer = $number[0], decimal = $number[1]";

echo PHP_EOL;

# with explode and list
list($int,$dec)=explode('.', 88.5);
echo "integer = $int, decimal = $dec";
?>
