php - 是否可以在我的函数中循环遍历 html 输出

Question

function star_bar( $data = array( ) ) {

    $output = "<b>Rating:</b> ";

    if ( $data["rating"] == 1 ) {

        $output .=

正如您所看到的，这非常不整洁，是否可能存在某种循环？这将使用从 mysql 数据库中提取的整数输出星形条。

Answer 1

代码

function star_bar($data = array())
{
    $output = "<b>Rating:</b> ";
    for ($i = 1; $i <= $data["rating"] / 2; $i++) {
        $output .= "<span class=\"star-icon full\">☆</span>";
    }
    if ($data["rating"] % 2 == 1) {
        $output .= "<span class=\"star-icon half\">☆</span>";
    }
    for ($i = 1; $i <= (10 - $data["rating"]) / 2; $i++) {
        $output .= "<span class=\"star-icon\">☆</span>";
    }
    $output .= "<br />";
    return $output;
}

说明

满星的数量每两次评级就会增加:0 和 1 的满星数为零，2 和 3 的满星数为 1，依此类推。因此，您将评分除以二，即可得到满星数。

您最多有一颗半星，而且只有奇数评级。因此，仅当您的评分除以 2 余数为 1(评分不是偶数)时才添加它。

空星星的数量与满星星的数量类似，除了它基于 (10 - $data["rating"]) (它随着评级的增加而减少)。
