计算单词在数组中显示的次数？

Question

我正在使用array_push来添加到一个数组，其中卡的数量是多少。

$array = array(); 
foreach($aiarray as $card) { 
    $cardss = card($card); 
    array_push($array, $cardss); 
} 

asort($array); 
print_r($array); 

这给了我我需要的，但现在我该如何搜索数组和说;

伪

if (*array contains > 2 of the same word) { 
    find out what word; 
    does the array contain more than one?; 
} 

Answer 1

这个怎么样？使用

if (in_array($word, $array)) { 
    $array_keys = array_flip($array); 
    $number_of_words = count(array_keys($array_keys, $word)); 
    if ($number_of_words > 1) { 
    echo "array contains word more than once"; 
    } 
} 

功能：in_array，array_flip，并array_keys

Answer 2

Array Count Values然后PHP Get Highest Value from Array

只是做

$count = array_count_values($array); 
$max_times = max($count); 
if ($max_times > 2) { 
    $word = array_search($max_times, $count); 
    .... whatever you need 
}
