如何兩個PHP計算

Question

結合如何有一定的PHP作爲加法對PHP計算

這是基本代碼

<?php echo (str_replace('.',',',round((str_replace(',','.',(str_replace('€','',$discount['discountedPrice'])))*1.2),2)))." Eur"; ?> 

，並想添加以下內容：

(str_replace('.',',',round((str_replace(',','.',(str_replace('€','',$discount['discountAmount'])))*0.2),2))) 

所以我想補充（+），看起來像這樣，但不知道如何把它：

(str_replace('.',',',round((str_replace(',','.',(str_replace('€','',$discount['discountedPrice'])))*1.2),2))) + (str_replace('.',',',round((str_replace(',','.',(str_replace('€','',$discount['discountAmount'])))*0.2),2))) 

Answer 1

你去那裏：

<?php 

$value120Percent = round(removeEuroChangeDecimal($discount['discountedPrice']) * 1.2, 2); 
# or if you really don't need rounding 
# $value120Percent = removeEuroChangeDecimal($discount['discountedPrice']) * 1.2; 
$value20Percent = round(removeEuroChangeDecimal($discount['discountAmount']) * 0.2, 2); 
# or if you really don't need rounding 
# value20Percent = removeEuroChangeDecimal($discount['discountAmount']); 

# change the fourth parameter to set thousands separator (to e.g. a space) 
echo number_format($value120Percent + $value20Percent, 2, ',', ''); 

function removeEuroChangeDecimal($value) { 
    return str_replace(',', '.', str_replace('€','', $value)); 
}
