Question

我有多个div，如下面的类

<div  class ="hub_categoryDeal Dubai  Healthcare BEAUTY HAIR_REMOVAL1 LASER_HAIR_REMOVAL Dubai"
<div  class ="hub_categoryDeal Dubai  Healthcare SERVICES HAIR_REMOVAL1 LASER_HAIR_REMOVAL Dubai"

类别名称如BEAUTY和SERVICES在类中。如何在简单的html find（）方法中获取它？

Answer 1

我不知道/无法为此找到正确的数组函数，但您可以获取所有类，然后过滤它们。像这样：

$html_string = '<div  class ="hub_categoryDeal Dubai  Healthcare BEAUTY HAIR_REMOVAL1 LASER_HAIR_REMOVAL Dubai"></div>"
<div  class ="hub_categoryDeal Dubai  Healthcare SERVICES HAIR_REMOVAL1 LASER_HAIR_REMOVAL Dubai"></div>';
$html = str_get_html($html_string);

$classes = array();
foreach ($html->find('div.hub_categoryDeal') as $element) {
    // push all the values inside the container
    $classes = array_merge($classes, array_filter(explode(' ', $element->class)));
}
$temp = array_count_values($classes); // check all the values
foreach($temp as $key => $count) {
    if($count > 1) { // if is repeated
        $found = array_keys($classes, $key); // get all the repeated thru their keys
        if($found) {
            foreach($found as $k) {
                unset($classes[$k]); // remove them
            }
        }
    }
}

echo '<pre>';
print_r($classes);

输出如：

Array
(
    [3] => BEAUTY
    [10] => SERVICES
)
