Question

让我们说我们有一辆价格在1000美元到5000美元之间的汽车。现在，当用户搜索开始的汽车时：

从999 $到1001 $
从1001 $到4999 $
从$ 4999到$ 5001

$rangeMin = (int)$searchedTerms->rangemin;
    //substract 10% from min range
    $rangeMin = (int)($rangeMin - ($rangeMin / 10));

    $rangeMax = (int)$searchedTerms->rangemax;
    //add 10% to max range
    $rangeMax = (int)($rangeMax + ($rangeMax / 10));

    for($i=0; $i< count($result); $i++){
        if( 
        in_array( (int)$result[$i]['price_min'], range($rangeMin, $rangeMax,1)) || 
        in_array( (int)$result[$i]['price_max'], range($rangeMin, $rangeMax,1) ) || 
        in_array( $rangeMin, range((int)$result[$i]['price_min'], (int)$result[$i]['price_max']),1 ) || 
        in_array( $rangeMax, range((int)$result[$i]['price_min'], (int)$result[$i]['price_max']),1 ) ) {
            array_push($final, $result[$i]);
        }
    }

Answer 1

简单的if语句应该有效：

return
    ($search['low'] >= $car['low'] && $search['low'] <= $car['high']) 
    || ($search['high'] >= $car['low'] && $search['high'] <= $car['high']);

见下面的测试计划here：

$car = ['low' => 1000, 'high' => 5000];

$search_positive_tests = [
    ['low' => 999, 'high' => 1001],
    ['low' => 1001, 'high' => 4999],
    ['low' => 4999, 'high' => 5001]
];

$search_negative_tests = [
    ['low' => 998, 'high' => 999],
    ['low' => 5001, 'high' => 6000]
];

function is_match($car, $search)
{
    return
        ($search['low'] >= $car['low'] && $search['low'] <= $car['high']) 
        || ($search['high'] >= $car['low'] && $search['high'] <= $car['high']);
}


foreach ( $search_positive_tests as $search )
{
    if ( !is_match($car, $search) )
        throw new Exception('(' . $car['low'] . ' => ' . $car['high'] . ') should have matched (' . $search['low'] . ' => ' . $search['high'] . ')');
}

foreach ( $search_negative_tests as $search )
{
    if ( is_match($car, $search) )
        throw new Exception($car['low'] . ' => ' . $car['high'] . ' should not have matched (' . $search['low'] . ' => ' . $search['high'] . ')');
}

Answer 2

以下内容应该可以解决问题：

header{
    width:100%;
    background-color: #607D8B; 
    color:#8BC34A; 
    font-size:200%;
    padding: 15px;
    position: fixed;
    z-index: 999;
    
}

article, aside, details, figcaption, figure, 
footer, header, hgroup, menu, nav, section {
    display: block;
}

.image{
    width: 100%;
}

body {

height: 1200px;
}

PHP检查其他int范围内的int范围
