是否可以循环我的函数中的html输出

Question

function star_bar( $data = array( ) ) {

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

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

        $output .= 
        "<span class=\"star-icon half\">☆</span>
        <span class=\"star-icon\">☆</span>
        <span class=\"star-icon\">☆</span>
        <span class=\"star-icon\">☆</span>

    if ( $data["rating"] == 2 ) {

        $output .= 
        "<span class=\"star-icon full\">☆</span>

    }

正如你所看到的那样，这是非常不整洁的，是一种可能的循环吗？这将使用从mysql数据库中提取的整数输出星形条。

这是一个非常简单的css星条源[{3}}

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

每两个等级的满星数量增加：0和1你有零满星，有2和3你有一个，依此类推。因此，您将等级除以2，即可获得满星的数量。

你最多只有一个半星，而且只有奇怪的等级。因此，只有当您的评分除以2时，才会添加余数为1（评分不是偶数）。

空星的数量就像满星的数量一样，除了它基于(10 - $data["rating"])（它随着等级增加而减少）这一事实。

Answer 2

function getStars($rating)
{    
    $ratios = array();
    $result = "";

    $lastStarIndex =ceil($rating / 2) -1 ;

    //fill all  
    for($i = 0; $i < 5; $i++)
    {
        if($i == $lastStarIndex)
            $ratios[$i] = $rating % 2  ? "half" : "full";
        else if($i < $lastStarIndex)
            $ratios[$i] = "full";
        else
            $ratios[$i] = "";
    }

    for($i = 0; $i <5 ; $i++)
        $result .= "<span class=\"star-icon " . $ratios[$i] . "\">*</span>";

    return $result;
}
print_r(getStars(10));
print_r(getStars(1));
print_r(getStars(3));
print_r(getStars(6));
