我希望将$ total作为一个数字的总和输出,但是每次我总结$ total时,它都会输出多个数字
$total =0 // i tried to use a number to sum them up
$computers = array(
"computer;DT-12;568,36;10",
"Samsung; RS; 562,26;11",
"Hewlett Packard; F12; 450,23; 23",
"Toshiba; LO-34; 454,23;8",
"Sony; Vaio 123; 232,23;5"
);
foreach($computers as $value)
{
$product= explode(";",$value);
$price = $product[2];
$count = $product[3];
$multiply = $count * $price;
$total += $multiply
}
预期输出:
$total = 27004 as one number
答案 0 :(得分:1)
您的代码中有一些语法错误。除此之外,您的计算看起来还不错,并且使用explode();
做得很好。
$computers = array(
"computer;DT-12;568,36;10",
"Samsung; RS; 562,26;11",
"Hewlett Packard; F12; 450,23; 23",
"Toshiba; LO-34; 454,23;8",
"Sony; Vaio 123; 232,23;5",
);
$total = 0;
foreach ($computers as $value) {
$product = explode(";", $value);
$total += (int) trim($product[2]) * (int) trim($product[3]);
}
var_dump($total);
您可能会检查一下数学是否正确。
int(27004)
