比较两个array_count_values数组 - 键和值 - PHP

I am counting the elements of an array and storing the result in an array using array_count_values.

我正在计算数组的元素,并使用array_count_values将结果存储在数组中。

Let's consider this is the output for this instance, which is created from an array, which was in-turn created with the help of explode.

让我们考虑这是这个实例的输出,它是从一个数组创建的,而这个数组是在explode的帮助下创建的。

magazine = Array(
    [avatar] => 1
    [essence] => 6
    [pie] => 1
    [multiplex] => 1
    [bill] => 2
    [nice] => 2
    [pie ] => 1
) 

ransom = Array(
    [multiplex] => 1
    [pie] => 2
    [avatar] => 3
    [bill] => 1
    [nice] => 3
    [essence] => 1
)

Now, I want to check if the elements in Array ransom are available in array Magazine. The loop should exit if the element in ransom is not available in magazine. (or) If the element exists, value of that element in ransom cannot be greater than the same element value in magazine.

现在,我想检查Array Magazine中是否有Array赎金中的元素。如果赎金中的元素在杂志中不可用,则应该退出循环。 (或)如果元素存在,那么赎金中该元素的值不能大于杂志中的相同元素值。

How can I achieve this? How to use nested foreach in this case? as I cannot use a simple for loop here because of the keys.

我怎样才能做到这一点?在这种情况下如何使用嵌套的foreach?因为钥匙,我不能在这里使用简单的for循环。

$ransom_temp = "avatar essence pie multiplex bill nice essence nice bill essence essence essence essence pie"
$magazine_temp = "multiplex pie pie avatar bill nice nice nice avatar essence avatar"

$magazine = explode(" ",$magazine_temp);
$ransom = explode(" ",$ransom_temp);
$countRan = array_count_values($ransom);
$countMag = array_count_values($magazine);

print_r($countMag);
print "<br>";
print_r($countRan);

if($n > $m){
    print "No";
    return;
}

foreach($countRan as $key1=>$value1){
    foreach($countMag as $key2=>$value2)
    if($key1 != $key2) || $value1 > $value2){
        print "No";
        return;
    }   
}
print "Yes";

You only need one loop:

你只需要一个循环:

$ransom_temp = "avatar essence pie multiplex bill nice essence nice bill essence essence essence essence pie"
$magazine_temp = "multiplex pie pie avatar bill nice nice nice avatar essence avatar"

$magazine = explode(" ",$magazine_temp);
$ransom = explode(" ",$ransom_temp);
$countRan = array_count_values($ransom);
$countMag = array_count_values($magazine);

print_r($countMag);
print "<br>";
print_r($countRan);

if(count($countRan) > count($countMag)) {
    print "No";
    return;
}

foreach ($countRan as $key => $value){
    // exit if key not exists in $countMag array
    // or exit if value in $countRan[$key] greater than $countMag[$key]
    if (!array_key_exists($key, $countMag) || $value > $countMag[$key]) {
        print "No";
        return;
    }
}
print "Yes";
